Using research results from the Humanoid Research Group of the Intelligent Systems Research Institute of AIST, two start-up companies approved by AIST — General Robotix Inc. and Moving Eye Inc. — working together with Pirkus Robotix Inc. and Dai Nippon Technical Research Institute, have developed a humanoid robot called “HRP-2m Choromet,” or “Choromet,” for short.
Chromet is 35cm high, weighs 1.5kg, and has 20 of freedom. It has triaxial force/torque sensors on its legs and accelerometer, gyroscope on its trunk, and a small, energy-saving controller developed at AIST that is driven in real-time by Linux (ARTLinux). Also developed at the same time at AIST was the base software that runs on the Linux system.
Choromet was developed to be small and inexpensive. For this reason, it uses a servomotor for hobby robots. Moreover, its link structure allows it to be made with metal plates, but designed so that there would be as little offset as possible in the joint axes. The rigidity of this robot has reached the level where the effectiveness of its motion patterns can be tested at the same level as movement patterns for humanoid robots.
