3-Wheel Robotics Chassis

Omnidirectional 3-wheel robotics chassis: for a gentle introduction to robotics

This Actobotics chassis for 3-wheel robot features aluminium mechanical parts. There are two large heavy-duty wheels at the front and one small wheel at the rear. All 3 of them are equipped with flanged ball bearings and are firmly attached to the chassis using a combination of adapters, shafts and hubs, enabling smoother movements of the robot. Indeed, your creation can turn in all directions with flexibility.

How can you improve your 3-wheel robotics chassis?

Assembly requires 2 Allen keys. Drive motors are sold separately. You will easily find some compatible models on our site.

The chassis accepts all Actobotics components, so you can optimise it at will with sensors, a laser scanner, a 3-axis gyroscope or even a camera.
