A development of humanoid robot HRP-2 is presented in this paper. "-2 is a humanoid robotics platform, which we developed in phase two of HRP. HRP was a humanoid robotics project, which bad run by the Ministry of Economy, Trade and Industry (METI) of Japan from 1998FY to 2002FY for five years. The ability of the biped locomotion of HRP-2 is improved so that HRP-2 can cope with uneven surface, can walk at two third level of human speed, and can walk on a narrow path. The ability of whole body motion of HRP-2 is also improved so that HRP-2 can get up by a humanoid robot's own self if HRP-2 tips over safely. In this paper, the appearance design, the mechanisms, the electrical systems, specifications, and features upgraded from its prototype are also introduced 07803-8232-3/04/$17.00 WOO4 IEEE
---We have de veloped a humanoid robot HRP-2P with a biped locomotion controller, stereo vision software and aural human interface to realize cooperative works by a human and a humanoid robot. The robot can find a target object by the vision, and carry it cooperatively with a human by biped locomotion according to the voice commands by the human. A cooperative control is applied to the arms of the robot while it carries the object, and the walking direction of the robot is controlled by the interactive force and torque through the force/torque sensor on the wrists. The experimental results are presented in the paper.
In this paper we present a humanoid robot, HRP-2P, which can walk, lie down and get up. We believe that HRP-2P (154 cm height and 58 kg weight) is the first humanoid robot that is the size of a human and can lie down and get up. Biped walking is realized by a walking pattern generator using a preview control and a feedback control. The lying down and getting up motions were made possible by HRP-2P's compact body with a waist joint and a novel motion controller.
