Here is a list of the projects with links I have come across so far. Am I missing anything good? Some of these are designed for animatronics, some as prosthetics, some as research tools, etc. If I couldn't find a name for the project, I tried to use the designer's name. I'm leaving out a number of proprietary expensive prosthetic hands, but they are generally not appropriate as robot hands. Maybe those can be the topic of a separate thread.
