Rocker Bogie

With this model I want to demonstrate the Rocker Bogie Suspension of the Mars Rovers. The Rocker Bogie Suspension is the de facto standard construction for a mobility system for rough terrain. It was used by the Mars Rovers "Spirit" und "Opportunity" and by the older "Pathfinder".
The special features of this construction:
  • no springs or suppresors are required
  • if all wheels are driven, even obstactles can be climbed that are largen than the wheels
