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
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
Parts list:
4 x 25mm Encoder Motor
4 x Plate 7x9
8 x Thread drive beam
8 x Shaft 4x80
16 x Shaft collar
Step 3: Mount the Four-link to the Frame
Parts list:
8 x Shaft 4x80
16 x Shaft collar
Step 4: The Suspension Spring and the Link Rods
Parts list:
4 x Suspension Spring
8 x Triangle plate 6x8
4 x Thread shaft M4
4 x Shaft 4x80
16 x Nylon stud
12 x Nylon spacer
4 x thrust bearing
16 x Shaft collar
8 x Rod end bearing
Step 5: Do the Last Step for 3 Times More
Step 6: The Circuit Boards
Parts list:
1 x Makeblock Orion
2 x Encoder Motor Driver
1 x Makeblock USB Host
1 x Wireless USB joypad
3 x RJ25 cable
Step 7: Do Some Magic to the Arduino-based Board ---- Makeblock Orion
The code is the same as the last project: How to Make an All-direction Vehicle with Mecanum Wheels
