How to Make a Mecanum Robot With Suspension
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.
The Frame
Parts list:
4 x Beam 0824 - 320
2 x Beam 0824 - 080
8 x Thread drive beam M4x40
