Shore Western has developed an Ankle-Foot Prosthesis Simulator with innovative kinematics and control technology that can accurately replicate the loading profile of a walking leg. The servohydraulic two axis simulator uses closed loop displacement control for the angular movement of the tilting platform, and mixed mode control for the axial load. Mixed mode is a powerful control technique that enables dynamic and accurate load programming while using a safer and more stable displacement control. This is made possible with their proprietary "Real Time Active Control" technique; a unique and powerful optimization algorithm that faithfully reproduces the desired waveform.

● Displacement or Mixed mode control (displacement PID with load command)
● Real Time Active Control (RTAC)
● Control system robustness allows experimenting with virtual spring model constraints to simulate soft tissue and tendon reaction forces
● Flexible Limit Definition (shown with red dashed lines)
