State of the Art: Prosthetist defines knee damping Otto Bock C-Leg
Virtual Prosthetist Virtual Biomechanist The MIT Knee: A Step Towards Autonomy
How The MIT Knee Works: Mechanism
Knee Position Axial Force Bending Moment Measured Local to Knee Axis (no ankle or foot sensors) How The MIT Knee Works:Sensors Amputee can use vertical shock system
Controlling Force, not Position Weight: 2.5 lbs. Stroke: 3 in. Max. Force: 300 lbs. Force Bandwidth: 30 Hz
Towards the Future: Distributed SensingMeasuring User Intent with Bions
Summary Advances in the science of legged locomotion, bioactuation, and sensing are necessary to step towards the next generation of O&P leg systems
