Fig. 13From: The mechanical structure of mobile module for new self-configurable intelligent environmentCross-sectional view of the locked leg and station. The figures show cross-sectional views that are parallel and orthogonal with the field respectively. The gap and the incline planes of the pin make the pulling and pushing pin motions smooth. The sponge, which is adhered to the bottom of the legs of MoMo3, helps the MoMo3 to fix to the field stablyBack to article page
