The TF8 actuator system, developed by Matt Carney, Tony Shu, and others is a powered prosthetic joint system. It was designed for use as a both an ankle, as well as knee prosthesis. However, previous testing had not used the TF8 system as a knee prosthesis. Over the course of several months, Tony Shu and I worked to transition an existing TF8 system to knee configuration and are currently evaluating the system on a variety of subjects.
I was responsible for physical integration of our Verdin electronics stack onto the new device and for designing end-of-travel stops to simulate a human knee. This involved designing a robust electronics mounting system and experimenting with a variety of end-of-travel stop designs and materials.
Please see the attached presentation for more details the TF8 upgrades.
