A motorized prosthetic device includes a joint member, a limb member, a pressure sensor, and a kinematic sensor. The pressure sensor indicates interaction between the motorized prosthetic device and the ground and the kinematic sensor measures torque at the joint member. A controller receives data from the pressure sensor and kinematic sensor and calculates a control signal based at least on the received data. An electrical motor receives the control signal and operates an actuator in accordance with the received control signal.
