11. 3 Wheel Actuation

12. Rock Collector Lifting Fixture
Problem
Creating space for the Rock Collector to pass over objects

13. Solutions Pulley System or Gearing System
Use actuators or motors to raise height of Rock Collector
Drawbacks
Weight, Spacing, Interference with other components
Modify a Transmission for the use of one motor for two functions
Code, Weight, Spacing, Intrinsic mechanics

14. Hinge Design Passive Method
Operates by utilizing the robot’s forward motion
