A legged robot "JROB-1" is developed for a robotics research platform as a result of inter-university research program on intelligent robotics supported by the Ministry of Education Grant-in-Aid for Scientific Research on Priority Areas in Japan. The JROB-1 features: 1) self-contained, 2) RT-Linux running on PG/AT processes vision and sensor processing, motion planning and control, 3) connected to a network via radio Ethernet as to utilize networked resources, 4) Fujitsu color tracking vision board and Hitachi general purpose vision processing board, 5) all parts are commercially available, and 6) it is extensible with respect to sensor, sensor processing hardware and software. JROB-1 is expected to be a common testbed for experiment and intelligent robotics research by integrating perception and motion.
