Society of Robots has a great video of a robot arm-clocks –

The robot arm is probably the most mathematically complex robot you could ever build. As such, this tutorial cant tell you everything you need to know. Instead, I will take shortcuts and just talk about the bear minimum you need to know to build an effective robot arm. Please bear with the math . . . enjoy!

To get you started, here is a video of a robot arm assignment I had when I took Robotic Manipulation back in college. My group programmed it to type the current time into the keyboard . . . (lesson learned, dont crash robot arms into your keyboard at full speed while testing)

    Yes ! The robots are nice (and probably very expensive), but those fluorescent pieces are very pretty, and probably cheap! I can think of 10 things to do with those.
