Introduction: 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.

Step 1: The Frame

Picture of The Frame

Parts list:

4 x Beam 0824 - 320

2 x Beam 0824 - 080

8 x Thread drive beam M4x40

4 x Plate 45°

8 x Nylon spacer

The chassis consists of a frame and 4 motor-wheel modules. Let's finish the frame first.

Step 2: The Motor and the Parallel Four-link

do mecanum wheels work on slopes like 60 and 90 degrees..???
like on stairs.
if so do you tried it..???
please suggest me.
i'm waiting for your reply.

sorry for the late reply.

Mecanum wheel can work on slopes less than 45 degrees.
