Shadow Robotic-Leg 2005
The leg was made for the Shadow Robot Co. as part of a contract from North Carolina A & T University.
Design and construction by David Buckley - 2005.
The prototype, constructed mainly from mdf, shows the range of movements of the leg.
The actuators are Shadow Air muscles, a development of the McKibben artificial muscle.
The leg was designed to hang from a frame and mimic the movements of a human control leg.
As usual, the weather was against outside photography and room was limited on setup at Shadow, so similar photographs of the final leg were never taken!

  • 2016 - enhancement to enable the leg to walk.
