Exactly... There are a lot of open source robot arms on thingiverse and youtube. Some of them are $100 dollar proof of concepts with basic RC servos [1] to full blown awesomeness like the BCN arm [2] with many flavors in between.

It would be super cool to get the prices of the control boards down, standardize the software stacks that run these things, and really integrate them into everyday life. For now, I suppose we have to watch a group of people reinvent the ARM every few months.
