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 robot’s forward

motion
