Build a robot arm

Want to build a robot arm yourself?  This video by Jacobk42 shows you how to easily make a DIY robot arm:

Using some assorted pieces of wood, springs, string and some odds and ends will allow you to make a cool looking Robot Hand! Looks like William Jakespear has lots more cool demonstration of what he makes on his Facebook Page. The hand straps to your wrist and your normal sized hand can then operate the huge robot hand. The springs that were scavenged form a bunch of pens allow the fingers to return the the straight position when you relax them.
