Hobbyists can develop a crawler base by using their own structure frames with the help of the sprocket wheels and rubber tracks we supply. This full set crawler base is available in our robotic base section. 

This kit consists of sprocket wheels, wheel hub adapters, rubber tracks, screws and nuts. All the key parts are made of plastic. By putting all the parts together, hobbyists can develop a robotic crawler base. The rubber track length is adjustable according to the need.
