Electrostatics: Good for Robot Grippers, and Lots More

I've had a lot of fun with electrostatics, but never thought to use it on a robotic gripper before. That's awesome!

Here's a video of some stuff stuck to my walls. https://www.youtube.com/watch?v=o3knDxQpPRo

I was playing around with a high voltage ion generator, and was able to stick things to my walls. I was thinking of using it for helping to hang posters so they can be re-positioned prior to using more permanent methods.

I was even able to hang a phone book on the wall once by sticking pages down one by one.
