While working on my first robot I ran into this problem. So I decided to make a quick second one just to keep me in the flow with all that new robotic-topics to learn. Inspired by an art installation I created the Gwünderer. This bot hangs on the wall inside a frame and shows up as soon as somebody passes by. Gwünderä stands for being curious about something. It is a Swiss dialect word. I thought it is a good match to what is the purpose of life of this little robot.
