A research group at Osaka University, led by Professor Arai, is developing a six-legged robot, with features of the design borrowed from insects. This robot walks on six legs, and it can use two legs as arms when needed, so it can pick things up and carry them. Robot called Asterisk. The six legs of the Asterisk each have four joints. The legs are arranged around the center at 60 degree intervals, giving the robot the same working range in all directions. There is also no distinction between the top and bottom of the robot. So if it falls over, it can get up easily by turning its legs the other way. One of original aims of researchers was to use this robot in rescue work. Also they would like it to help with things like building maintenance.
Researchers hope to develop it further, so it could be used in situations like the recent earthquake. For more information watch video below.
