Modern Scientists "Gets Medieval"

OK, maybe not medieval. But it had to be a catchy title...

This guy built a "robot" from wood, string, a weight, and some wheels.

I love the part when he talks about "string programming language." The great thing about string is that it is a significant improvement of sinew 1.0, which had some big flaws...

Interesting, how big an achievement this basic machine was at its time.
