How to Make a Mecanum Robot With Suspension

Mecanum Robot With Suspension, Not Limit to 360 Degree!

Mecanum wheels are often used to build a competition robot, which can do omni-directional movement. When the number of mecanum wheels is greater than 3, the wheels may be non-coplanar. That why the suspension system is invented. This instructables will show you how to build a 4WD mecanum car with independent suspension.
