Lock down the Joint, Please

[Hughzie]

• Use the axle to provide torsion on its own with cantilever springs controlling pitch
• Use a cantilever spring as the axle to provide pitch and a large torsion spring for roll
• Use a single flexible axle which twists and pitches according to requirements

[Hughzie]

• Using a cantilever beam coupled with a rubber (polyurethane) rod to join sections and passively actuate pitch and roll respectively
• Deflections and stresses calculated in Matlab
• CAD Models added to robot assembly
• Closing this initial design issue
