Mochibot is a sea urchin robot with 32 legs. It is a structure in which each leg moves in a desired direction repeatedly. This kind of appearance may be more appropriate to roll than to walk. The advantage of the sea urchin robot is that it does not fall. There is a bridge in every direction, so it is unstable at all.
It is possible to draw a circle or to draw a trajectory as well as to go straight. This robot was developed by Keio University and the University of Tokyo research team. The official name is Continuous Shape Changing Locomotion of 32-legged Spherical Robot using 32 consecutive deformed legs.
The robot has a 30-sided structure, and its legs stretch or shrink in three stages like a folding telescope. The maximum length is 60cm. Using this structure can be expected to be used in planetary exploration and disaster areas. For more information, please click here .
