The MIT Knee: A Step Towards Autonomy : The MIT Knee: A Step Towards Autonomy
Slide13 : How The MIT Knee Works:
Mechanism
How The MIT Knee Works: Sensors : How The MIT Knee Works: Sensors Knee Position
Axial Force
Bending Moment
Measured Local to Knee Axis (no ankle or foot sensors)
Amputee can use vertical shock system
