Videobot is an unusual robot. It does its best to look at you, to follow and move along with you. While moving around, it tries to see who is in front of it. As participant you can help Videobot follow you, so squeaking and beeping, it can get to know you.

Bart Koppe approached me to help him with the facial recognition on Video Bot.
On a Raspberry Pi I made a python program that detects faces and then moves a screen to the same position as the detected face, it then takes a picture and uploads this to a website.
