You can YouTube videos of this and it's pretty cool. There's also a Ratheon 3 suite from USA that tracks body movement with enough speed and precision that you can see a video of it boxing. Super cool. I will link a couple videos. They are very inspirational projects. When you research the beginnings of where both these suites started they used off the shelf simple items and used medium sized motors at the joints to make it happen.
One of the first things that made me want to post is the companies name. CYBERDYNE INC , really lol ? They took their name from the Terminator movie and the movie "I Robot" took their name from a real company . SMH
