Rock Collector Lifting Fixture
• Problem– Creating space for the Rock Collector to pass
over objects
![Page 13: Group 11- ASME Design Competition Final Design Review](https://reader036.vdocuments.mx/reader036/viewer/2022081505/56815b99550346895dc99e50/html5/thumbnails/13.jpg)

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

Hinge Design
• Passive Method– Operates by utilizing the robot’s forward
motion
