Powered prosthetics, bionic systems, and robotic devices being developed in the research laboratory are becoming quite sophisticated. These robotic systems are made possible thanks to advancements in microprocessors, batteries, sensors, and intelligent controllers, and will increase the offering of prosthetic systems in the commercial market. We are often asked the question, “Why should I choose a powered ankle device over the recent advancements in energy-storing carbon-fiber keels?” By highlighting some of the ongoing research and some of the advantages we have observed and reported on, we hope to answer that question.
