This is my latest project “Robotic arm that records and plays movement”, I took an IKEA Terial lamp and hacked it into a fully functional, motion recording, robotic arm. 
This project answers to a need I had: a Third hand that holds a camera while I perform a test and takes photos/videos (useful when you’re stuck at the lab late at night, and suddenly need a photographer).
The downside to a robotic arm was obvious – It needs to be programmed, and it is the last thing you want to do when you need to make a video. So I made it motion capturing device as well…
