DARPA Robot ARM Simulator

At the Smithsonian Institution's National Museum of American  visitors can play interactive games with the DARPA Autonomous Robotic Manipulation (ARM) robot, see what the robot "sees" on video screens behind the robot and learn how robots process information. The exhibit teaches visitors about how robotics can impact society and encourages young people to pursue careers in science and engineering. DARPA is also offering the public the opportunity to develop and test code to perform tasks in the robot simulator, then upload that code to an actual robot and watch it execute the task in real-time via the web.

The DARPA ARM robot is a cutting edge robot designed as a tool for researchers at leading U.S. universities and research labs to find ways to enhance the types of tasks robots can perform while minimizing the amount of human input necessary.

Google Android@Home and Cloud Robotic Apps on Wheels

Google announced at Google IO conference 2011 that they will supply Android@Home framework for home automation to developers, giving them the ability to think of "every appliance in your home" as a potential accessory for your phone. The Google team teased ideas like lights turning on and off based on calendar events, applications talking to washing machines, games automatically adjusting for mood lighting, and basically little green dudes taking care of all the menial duties in your house. One amazing demo was a concept, Android-powered device hub called Tungsten. Using RFID embedded into CD cases the device was able to detect the CD and add it to your library. Another touch and it started automatically.

Google also said it teamed with iRobot to create a Android applications for the iRobot Ava mobile robotics platform. iRobot CEO Colin Angle showed off a prototype AVA robot which will actually be on the market and available to developers later this year. The AVA robot works by grafting an Android tablet onto a mobile style of robot body that looks a lot like a pillar with a wide wheelbase. That base then attaches to a Motorola Xoom tablet that is not only the brains of the robot, but its sensor array. AVA is able to make maps of the areas that it navigates, as well as avoiding both stationary and moving objects, with a speed of up to 2 meters per second. The developers used an Android-based tablet because it had what they needed, but according to sources close to the project, that they are open to working with other types of tablet PCs. Business oriented versions of the robots are expected to go on sale in 2012.

Google + Android + ROS = Cloud Robotics

Developers at Google and Willow Garage announced a new rosjava library that is the first pure-Java implementation of Robot Operating System (ROS). This new library was developed at Google with the goal of enabling advanced Android apps for robotics. The library, tools, and hardware that come with Android devices are well-suited for robotics. Smartphones and tablets are sophisticated computation devices with useful sensors and great user-interaction capabilities. Android devices can also be extended with additional sensor and actuators thanks to the Open Accessory and Android@Home APIs. The new rosjava is currently still under active development (alpha release mode) and there will be changes to the API moving forward. For early adopters, there are Android tutorials to help you send and receive sensor data to a robot.

EU Transport Vision 2050 might boost Personal Rapid Transit (PRT)

Image: ULTra Ltd.
The European Union announced plans to ban all petrol and diesel powered cars from cities by 2050 in a draconian plan designed to reduce carbon dioxide emissions by 60 percent.
European Commission, the executive body of the EU, wants 50 percent of Europe’s vehicles to be zero emission by 2030 and conventionally fuelled vehicles to be banned from cities altogether by 2050. The Brussels directives and new taxation of fuel would be used to force people out of their cars and into "alternative" means of transportation, says EU Transport Commissioner Siim Kallas.
"That means no more conventionally fuelled cars in our city centers," he said. "Action will follow legislation – real action to change behaviour."
The measures could "dramatically reduce Europe's dependence on imported oil and cut carbon emissions in transport by 60% by 2050", says the Commission.
Key goals of the 'Single European Transport Area' (PDF) by 2050 are: no more conventionally fuelled cars in cities; 40% use of low-carbon fuels in aviation; at least a 40% cut in shipping emissions; and a 50% shift of medium distance inter-city passenger and freight journeys from road to rail and water-borne transport.
The plan also says that by 2050 the majority of medium-distance passenger journeys - those above about 300 km (186 miles) - should be by rail.
All core network airports should be connected to the rail network by 2050, with all core seaports "sufficiently connected to the rail freight and, where possible, inland waterway system".
For longer-distance travel, and intercontinental freight, air and sea travel will benefit.

Personal rapid transit (PRT)
Personal rapid transit (PRT), also called personal automated transport (PAT) or podcar, is a public transportation mode featuring small automated vehicles operating on a network of specially-built guide ways. PRT is a type of automated guideway transit (AGT), a class of system which also includes larger vehicles all the way to small subway systems. PRT offers personal, on-demand non-stop transportation between any two points on a network of specially built guide-ways’. A PRT system consists of a number of small automated vehicles (seating 2 to 6 passengers) combining the desirable aspects of the private car (private travel at any desired time) with the social advantages of public transport (no congestion and parking issues).

First Public PRT at London Heathrow Airport

In summer 2011 the first public and commercial PRT system anywhere in the world will open at London’s Heathrow Airport. Commissioned by BAA (formerly the British Airport Authority) the ULTra PRT system comprises some 4 kilometers of guideway and will link one station in Terminal 5 to two remote stations in the Business car park.
ULTra PRT (originally Advanced Transport Systems Ltd) began developing the system in 1995, in association with the University of Bristol. The ULTra system emerged from systematic engineering analysis as the optimum solution to urban transport problems. By 2001, the company had established a 1km test track in Cardiff, where it has conducted trial runs of several generations of PRT vehicles. In 2005, ULTra PRT was chosen to build the system at London's Heathrow Airport.

PRT for the world’s first carbon neutral City

In the heart of Abu Dhabi work has started on the most ambitious sustainable development in the world today. Masdar City will be the world’s first carbon neutral, zero-waste to landfill, car-free city powered entirely by alternative energy sources. Masdar City will be built on six and a half square kilometres and will grow eventually to house 1,500 businesses, 40,000 residents and 50,000 commuters.

There will be no fossil fuel cars within Masdar City. The city will be a pedestrian-friendly environment, with a Personal Rapid Transit system (PRT) available for longer journeys.  The PRT vehicles will travel at speeds up to 40km/h, with the longest routes in the city taking around 10 minutes. Ultimately there will be 3,000 PRT vehicles serving 130,000 trips/day over the 85 stations.

Turkey Signs Unmanned Aircraft System Agreement

Turkey will become an important industrial partner for a next-generation Unmanned Aerial System (UAS).
Image: Cassidian, Talarion
A Memorandum of Understanding (MoU) was signed between Cassidian on behalf of EADS Deutschland GmbH and Turkish Aerospace Industries, Inc. (TAI) to establish a close collaboration in the Talarion programme. The MoU was signed May 11th, during an official ceremony at the 10th International Defence Industry Fair (IDEF) held in Istanbul.
Signed in the presence of Murad Bayar, The Honourable Undersecretary for Defence Industries and Thomas Kossendey, Germany's Deputy Defence Minister, this new agreement further reinforces the presence of Turkey in Unmanned Aircraft System (UAS) multinational collaborative programmes.
Talarion is the European programme for a next-generation Medium Altitude Long Endurance (MALE) advanced Unmanned Aerial System (UAS) to fulfil the requirements initially placed by France, Germany and Spain for future unmanned long endurance surveillance and reconnaissance missions. The novel aspect of this approach is a modular design and the integration of the UAV in a network-enabled operations scenario.
Turkey has always advocated to participate in this major European programme with the Undersecretariat for Defence Industries (SSM) agreeing significant investment and integration in the Talarion prototype programme team by major companies of the Turkish industry led by TAI (Turkish Aerospace Industries, Inc.).
The prototype will be the first development standard following an interactive design approach. First flight of the prototype is scheduled for 2014. To achieve this goal, Cassidian has created a dedicated co-located plateau phase with engineers from France, Spain, Turkey and Germany including main suppliers. Today around 160 engineers are working in the Talarion plateau.
Being the first Unmanned Aerial System that will operate within civil airspace, Talarion can be used for a variety of security missions amongst others such as anti-piracy, drug control, border protection and ecological and natural crisis management.

Next Generation UAVs

Image: Boeing Phantom Ray

Boeing announced on May 3, that Phantom Ray unmanned airborne system (UAS) successfully completed its first flight April 27 at NASA's Dryden Flight Research Center at Edwards Air Force Base, Calif.
The 17-minute flight took place following a series of high-speed taxi tests in March that validated ground guidance, navigation and control and verified mission planning, pilot interface and operational procedures. Phantom Ray flew to 7,500 feet and reached a speed of 178 knots. The Phantom Ray is expected to have an operating altitude of 40,000 feet and a cruising speed of just over 600 mph, not so far from the speed of sound.

Disaster Robots 2011 - Report from Japan

Urgent Needs of Disaster Response Robots in Japan 2011
As reported here before disaster respond robots have been used to get the damaged Fukushima Daiichi Nuclear Power Plant under control and to support also other disaster response missions in EQ and tsumani devastated regions in Japan. According to Prof. Hajime Asama, Chairman of the Robotics Task Force for Anti-Disaster (Robotad) and member of Remote Control/Robotics Project the needs for robots is very high. At his recent ICRA 2011 Special Forum Presentation in Shanghai he listed missions for stabilization of the cooling system, containment, decommission to reduction of radiation exposure of workers. Main robotic tasks include debris cleaning, radiation survey and mapping, surveillance inside the buildings (images, radiation, temperature, humidity, oxygen concentration, etc.), shield and decontamination, etc.
Prof. Asama mentioned also the need of disaster robots for search and rescue of victims, inspection, diagnosis and recovery of plants and facilities, surveillance of coast underwater, mapping of the damaged area, power assist for heavy load tasks and also for mental care of evacuees.

Robot Operations since April 6th
Robots started operations at Fukushima Daiichi NPP April 6th, when the first unmanned construction system (UCS) such as remote controlled crawler dumps arrived.
On April 10th the first remotely controlled combat-proven Micro Air Vehicle T-Hawk of Honeywell took top view images and videos of the damaged reactor buildings unit 1, 3 and 4
On April 17th the first mobile Packbots of iRobot entered the first floor of reactor building 1, 3 and 4 and transmitted the first images and videos from the reactor inside.

The current challenge for the robot teams is to understand the dynamically changing situation at Fukushima Daiichi and to propose optimal solutions utilizing robot technology according to the day-by-day mission, tasks and working environment conditions. Technical challenges are i.e. the tolerance against radioactive environment, implementation of communication systems, measurement by sensors, mapping, battery and power supply. Other issues are operation planning and training of operators.

Disaster Robot Candidates 2011

Image: Brokk 90
There are many foreign and Japanese candidates of robots for coming operations underway such as Packbot and Warrior from iRobot, micro UAV T-Hawk from Honeywell, surveillance and reconnaissance robots Talon and Dragon Runner from QinetiQ, the remote controlled eavy-duty lifter Bobcap, and the Swedish demolition robot Brokk 90.    

Image: IRS, KOHGA3
Image: IRS, Quince
Among the Japanese robot candidates are Yamaha's RMAX - the worlds most advanced non-military UAV, mini rescue robot KOHGA3 from Kyoto University and the most advanced rescue robot Quince developed by Chiba Institute of Technology, Tohoku University, and IRS.
For the moment, the taskforce is recommending the use of the compact Japanese-made Quince robot, which has two main caterpillar tracks and four smaller protruding ones which can be angled up or down to enable it to climb over debris and up stairs.

Moni-Robo developed by Japan's Nuclear Safety Technology Centre to operate at lethal radiation levels.
UMRS and the snake-like robot Soryu developed by IRS, the monster robot Enryu from tmsuk, the NBC anti-terror robot FRIGO-M from Mitsubishi, but also therapy robot Paro.

But before these robots can be mobilized many technical and operative issues have to be considered and investigated. Mobilizing a robot without any consideration could complicate the situation and may even hinder work. The first step is to extract in detail the missions and tasks for the robot system to do and to investigate the environmental conditions such as working space, debris and obstacles, temperature and humidity, lightning condition, radiation level.
The next step is to propose a solution including selection of robot technologies, reinforcement, modification and implementation. Planning includes estimation of radiation dose, access route, optimization minimum operation time. Important is also conflict resolution of radio frequency.
Before robot operations can start operators have to be trained, a operation room has to be setup, reservation of parking and decontamination space for robots is needed. Power supply and communication cables have to be in place as mapping facilities.
The final stage is the robotics operation including monitoring of radiation dose and life time estimation, decontamination, battery replacement, maintenance, management of operators´radiation exposure.

Lessons learned so far and future issues are the examination of the political strategy to sustain technology developed for nuclear disasters. An organization for quick response to emergency and disaster is needed as  international cooperation framework for mutual technology support.


Japan has learned that a nuclear disaster can happen even in Japan and that sometimes military robots are needed to cope with extreme disaster conditions. Today Japan is prohibited to make military robots and therefore dependent on foreign support.

Parallel-wire Robot for Solar-Thermal Plants

Credit: Fraunhofer IPA

Researchers from German Fraunhofer Institute for Manufacturing Engineering and Automation (IPA), have developed a parallel-wire robot that might pave the way for an innovative concept for automation solutions to handle extreme requirements. One application might be lifting 7 tonne solar collectors, consisting of dozens of parabolic mirrors, for the Desertec consortium whose big idea is the building of gigantic solar-thermal plants in the desert. Desertec has calculated that if just 1% of the Sahara was devoted to solar energy production, enough electricity would be generated for the entire world at current annual levels of consumption.
IPAnema demonstrator robot
The IPAnema demonstrator robot consists almost entirely of cables and winches. The winches are fixed to movable square metal scaffolding. Held between the cables, which are controlled by the winches with the aid of a computer, is the tool, known as the end effector. In the past, it was hard to predict what the result would be when the actuators were moved, but now commands to the winches can be given in a completely synchronised way, thanks to computer modelling.
Compared with conventional industrial robots, the IPAnema wire robot boasts a large working area (2 m x 2 m x 1.5 m), high speeds up to 10 m/s and extreme acceleration >10 g and a wide payload range from 1 kg to 400 kg. These characteristics can also be adjusted in line with a specific problem: The working area can be up to 100 m x 100 m x 30 m depending on the application. The efficient transfer of force through the wires means each wire can support a payload of several tonnes. The robot is controlled by a real time-capable NC control system which can be programmed easily via the tried-and-tested G-Code (DIN 66025). A programmable logic controller (PLC) can be connected as an option, enabling existing plant to be integrated easily.

Intutitive Robot Control

Credit: IPA
In the future robots will learn how to move by imitating human movements. Researchers at the German Fraunhofer Institute for Manufacturing Engineering and Automation IPA in Stuttgart, have developed a new intuitive robot controlling system based on movement imitation. With help of handheld sensor device that contains various movement sensors, also called inertial sensors, the user can control a robot arm by only moving its own arm. The researchers have developed special algorithms that fuse the data of individual sensors and identify a pattern of movement. That means the device can detect movements in free space. The new system has also numerous applications in medicine such as gait analysis and control of active protheses.  Fraunhofer will presented the new system at the Sensor+Test trade fair from June 7 – 9 in Nurenberg, Germany.

Floating Telepresence Robot


Sony CSL has developed a floating avatar system that integrates a blimp with a virtual avatar to create a unique telepresence system. Our blimp works as an avatar and contains several pieces of equipment, including a projector and a speaker as the output functions. Users can communicate with others by transmitting their facial image through the projector and voice through the speaker. A camera and microphone attached to the blimp provide the input function and support the user's manipulation from a distance. The user's presence is dramatically enhanced compared to using conventional virtual avatars (e.g., CG and images) because the avatar is a physical object that can move freely in the real world. In addition, the user's senses are augmented because the blimp detects dynamic information in the real world. For example, the camera provides the user with a special floating view, and the microphone catches a wide variety of sounds such as conversations and environmental noises.

From Stealthy Helicopter to Stealthy Robot

The attack on Bin Laden used stealthy helicopters that had been top secret according to The New York Times, refering to aviation analysts, who studied news photographs of the surviving tail section revealing modifications to muffle noise and reduce the chances of detection by radar. The commandos blew up one of the helicopters after it was damaged in a hard landing.

U.S. Stealthy Helicopter Program

The U.S. military first started its helicopter stealth program in the 1980s, with AH-6 Little Bird attack helicopters. In the 1990s, U.S. Special Operations Command reportedly began working with Lockheed-Martin and Boeing to take some of the stealth technology used on the F-117 Nighthawk attack aircraft, and apply it to MH-60 Black Hawks. In 2004 the stealthy Comanche helicopter project was canceled after billions of dollars in cost overruns. With the lack of anti-aircraft threats in Iraq and Afghanistan, Army officials decided that full-scale production of stealth copters was not worth the cost.

Researchers at Lockheed Martin Advanced Technology Laboratories (ATL) are working also on future military robotics systems that will be expected to perform with the same context understanding and impact awareness as their human counterparts. These capabilities will be required for both specific missions such as reconnaissance and surveillance as well as in everyday operations. In 2010 ATL has launched a research effort that focuses on developing a robot that could dynamically determine the path of least detection and audibly detect threats. To operate robustly, robots must be capable of perceiving various aspects of the world and reasoning over an integrated world model. Lockheed Martin ATL has developed a multi-layered world model representation that combines obstacles, threats and light sources to create a complete indivisilility model that can be used for planning in complec environments.

The robot is capable to covert robotic movement for reconnaissance, real-time audible detection and avoidance of threats, provides situation awareness via video and still imagery, extends the awareness of the warfighter while reducing risk.

The bot listens for sounds of human activity and the based on those sounds, and some clever programming, makes a guess as to where the humans might be looking. Then, if it needs to, the robot will find itself a dark hiding spot. The robot is equipped with a 3D laser scanner that allows the bot to create detailed maps of the building or area it is in. Along with a set of acoustic sensors that allow the robot to localize footsteps and voices, it can make a fairly accurate predictions about where you are on the map. When the robot sense a human is near it takes its pre-determined escape route to the dark and waits for the danger to pass, which means it may not be so stealthy in places lacking darkness or escape routes.

Swedish Demolition Robots Arrive at Fukushima Nuclear Plant

Credit: Brokk
Swedish Brokk, the world´s leading manufacturer of remote controlled demolition machines, is delivering two Brokk 330 Diesel robots and a brand new larger robot to Fukushima nuclear plant in Japan. 
The first task for the machines is to provide access to highly contaminated areas and clean up contamination. “One key difference between Brokk’s demolition robots and other robots currently on site is that our machines are capable of carrying out multiple different and tougher tasks, such as tearing down concrete structures and take care of heavier contaminated materials” says Martin Krupicka CEO of Brokk. 

The first contact with Brokk and its Japanese partner BGE Company Ltd was taken soon after the accident at Fukushima, as Brokk demolition robots are known globally for decommissioning and material handling in radioactive environments. 
Brokk has successfully delivered robots for demolition, decommissioning and disposal of radioactive material to the nuclear industry for over twenty years, including to the USA, France, Great Britain, Russia and Japan. Brokk machines have for example been used for decommissioning and cleanup at Chernobyl in Urkraine. Brokk was chosen for this extremely challenging work by Taisei Corp, which works for TEPCO at Fukushima, because of  our extensive experience in the nuclear industry. Brokk has over two hundred machines at various nuclear sites worldwide.
