Final Design



The function of the Tālārius is to assist in the mobility of its user and replicate human movement without human intervention.  The motion of the prosthesis will be operated by a motor that moves on a hinged threaded rod.  The threaded rod will be on a pin connection to the arch part of the foot.  On the other end of the threaded rod the motor will be free to move along the threaded rod to change the orientation of the prosthesis with respect to the ground.  The part will be able to sense the ground using pressure sensors throughout the length of the foot that will record data on the circuit board and then send a signal to the motor to adjust the foot, so that it satisfies the criteria of two-thirds body weight on the heel.  This process was set to take one second to perform a step and one second for the foot to return to its original position.  The part where the heel meets the arch of the foot is designed to perform as a hinged support.
