Bogie portion of the suspension links the middle wheel to the rear wheel.
Estimated Time: 30 minutes per side = 1 hour total
Parts:
- 1 * 117mm aluminum beam
- 1 * 122mm aluminum beam
- 1 * Rear steering corner
- 1 * Fixed knuckle
- 1 * Bogie pivot
- 1 * Steering knuckle
- 1 * Servo actuator module
- 11 * M3 nut installation tool for 2 nuts, 12.5mm apart
- 2 * M3 set screws
- 24 * M3x8mm bolts
- 24 * M3 washers
The 117mm extrusion connects the Rear Corner and the angled side of the Bogie Wheel part.
The 122mm extrusion connects the Bogie Wheel part on the straight side, and the Fixed Knuckle. The extrusion extends from the open side of the Fixed knuckle.
The Rear Corner should extend out away from the body when the assembly is mounted.
Repeat for other side of rover.
Sawppy v1 has a design flaw where it is easy to make the mistake of using the left side Bogie-Wheel part on the right side of the rover. (And vice-versa.) Several rover builders were caught by this, and I am contemplating several ways to improve. In the meantime please be aware: If a Sawppy rover's two middle wheels are splayed out rather than parallel with each other and aligned with the body, it is because their Bogie-Wheel parts had been installed left-right reversed from intended. (Thanks to Tim for sharing these pictures.)
