Robot Lady from Germany

Credit: DFKI Bremen

The lastest version of German robot lady AILA, developed at the DFKI Bremen Robotics Innovation Center, will demonstrate at CEBIT 2011 human like object handling with two arms supported by digital product memory. AILA consists of a complete anthropomorphic upper body mounted on a wheeled mobile plat-form. The upper body consists of two arms, each of them with seven degrees of freedom, a torso with four joints, and a head with two degrees of freedom. The robot is equipped with a stereo camera in the head as well as a 3D-camera on the torso used for object and scene recognition, and pose estimation two computers for vision processing and motion control, one located in the head and one in the torso the “nervous system” consists of three independent CAN-lines for communicating with the arms and torso, GigaEthernet connection for the stereo camera, and RS-485 for the servos moving the pan-tilt unit on the head.

The mobile platform consists of six wheels with two degrees of freedom each, one for the steering axis and one for driving the wheel. These are controlled by two independent CAN-lines. The steering axis can be positioned in any direction, making the mobile platform extremely versatile – it can navigate autonomously in slightly rough indoor environment because each pair of wheels is connected with the platform through a non-actuated rotary axis. Two laser scanners monitor the environment, recognize the relevant working area and therefore support a precise approach towards the objects to be handled.
