A robot drawing with coloured light
This machine creates light drawings. It is more a development platform for an upcoming project than a finished robot. So I've been very surprised about the enormous feedback and dozens of blogs writing about it. Thanks a lot for this. So I suppose it's time to come up with a bit more information:
It's a three-wheeled platform that is able to draw images with coloured light using rgb-leds mounted on the top. While the robot is moving a photo is taken with a long exposure time. The graphics are created on the computer. A program then reads the image file and sends wirelessly the data to the robot which converts it into motor movements and turns on and off the light with the given colour values.
Besides from drawing my christmas greeting in 2009 it's the development platform for a succeeding model that will draw a series of "paintings" for a magazine. More about this in a few weeks.
