compliant shuffler mechanism 003

This was the third iteration of a compliant shuffler mechanism for a walking combat robot.

The feet are printed in TPU and held to the top panel with a small #4 plastite screw.

The general concept worked, but there is room for optimization.

• Far too much friction between the feet.
• Cam was to soft to maintain position on shaft. It started to free spin eventually.
• Compliant section of the foot was too thin and prone to breaking.
• Foot could over-rotate and become bound if spun to fast.
• Foot traction area was not well optimized.
