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
• Drawbacks
• Code, Weight, Spacing, Intrinsic mechanics

14
Hinge Design

• Passive Method
• Operates by utilizing the robots forward motion
