With built-in motor drive circuit on the side boards, it gives more space to install other functional modules. To reach higher speed and power, hobbyists can install different motors and motor drive.

This is a patented and well developed crawler chassis. It comes with a main base board, which can be installed with different accessories, such as standoffs, battery holders, sensor modules and additional boards like a piece of PCB or breadboard.

Its rubber tracks are geared with 2 drive wheels and lined up with 16 pairs of bearings serving as idlers so that the chassis will not have the problem of track-slip.

Its patented MC-2 speed measuring system is more precise and reliable than the encoder measuring system that is commonly applied to other kinds of chassis. This crawler chassis is operated by 2 gear motors and each of them is matched with a L9110 IC, which generates much higher power with easier heat dissipation.

Power can be supplied either by the pitch 2.54mm connectors via crimped jumper wires or from the system via shorting blocks.
