The Write LMR Challenge
The rules here are simple:
- Make a robot that one way or the other writes either "letsmakerobots.com", or "LMR" the way you like it.
- Shoot it on video, enter it as a robot.
- Best entries will be promoted / used to promote LMR - Fame, envy, marvel, admiration and respect is the prize!
Your robot can shape the letters in clay, burn it on your sisters dog with a laser, build them out of breadcrumbs.. or draw it with a pencil on a piece of paper. Anything goes, as long as the letters are clearly written, and the video shows the progress.
Sample code is VERY welcome - perhaps this can be done simple by a "start-here-robot" - that would be way cool, and with some simple code that others could adapt and try at home!
Make sure that you have plenty of light on the video - best shot outside in daylight - it is going to be featured, so we need it to be sunny ;)

@ Mon, 2011-08-08 16:25
Thanks.
The wires are there because i ran out of batteries, one acble is to power the arduino and one is connected to a voltage regulator to power the 3 servos. Its a mess testing it out with wires...

low geared dc morors would
low geared dc morors would probably be good enough, the servos have problems of their own, 2 servos ordered at the same time(probably from the same batch) of the same brand and same specs does not move the same..... :)
