Product Description

This is the perfect chassis kit to get started in robots. The chassis features four gearmotors with four 65mm wheels. The chassis plates are cut from plywood with a wide variety of mounting holes for sensors, controllers, power, etc. Simply bolt the two pre-cut platforms together, attach the motors and wheels and add 4 motor drivers and controller. This kit includes all of the parts needed to assemble the chassis as well as a 4xAA battery holder.

Please note that 4 gear motors require 4 motor drivers (H-bridges).  For a simpler first robot many prefer the Basic Chassis with gear motors and wheels.

Note: The chassis requires assembly.  Wires and connectors must to soldered to the motors (wires and connectors not included).  The battery holder requires that a connector be soldered to the wires (connector not included).
