I have posted a short video on YouTube showing Bill Powers’ Little Man 2 demo in operation. The URL is https://youtu.be/t-mQTQUa8Q0
This version of the demo was written by Bill in the Delphi programming language for Windows and lacks some of the features present in his original C-language version, which was DOS based. One difference is that it lacks the Level 1 control systems for muscle length and tension. Instead of setting the references for these Level 1 controllers, the Level 2 joint-angle controllers are assumed to output joint torques directly.
