Although it can be used with a variety of robotics platforms, the JetBot Chassis Kit V2 is the official chassis for the SparkFun JetBot AI Kit. The ABS plastic used to make the chassis plates is 3.5 mm thick and has numerous mounting holes for sensors, servos, controllers, power, and other components. It is easy to assemble; all you need are the few included screws for construction, and you will have a sturdy 2WD robotics chassis. An excellent cost-effective choice for desktop robots. Two motors, two wheels, frames, a ball caster, and all the necessary assembly supplies, including screws and standoffs, are included in the JetBot chassis kit. Additionally, the materials needed to add an optional camera mount to your chassis are included. Note: A motor controller is not included in the JetBot Chassis Kit.
