Featured Thing!

Description

GarabatoBOT or in english, DoodleBOT, is a little robot that can make simple doodles in a white-board.
It's a really simple design: 2 stepper mottors with its drivers pcb, one Atmega328 and a bluetooth modem to control it wireless.

There are two ropes linking the up corners to the pulleys. The rope is collected by the pulleys when the motors are turning.

The structure has 5 different parts: one main body, two arms and the two pulleys.

The grey bag contain the battery (2s-1A) and also is used to go down the gravity center.

The page is partly in German, partly in English.
Let me know if U need a help understanding it.

Enjoy!
Nice idea to have the motor on the gondula. We had 'em on the upper corners of the drawing board. On tip: if the marker is close to the points that the string rotates around the thing becomes much more stable. It still pendels a bit, but it pendels now around the tip of the marker. Also the mathematics gets much simpler.

We endet up using the felt tip pent as the axis itself, attaching the strings to short sections of tube that loosely fit arount the pen. And we used a 3rd tube section to attache a weight, much the same as U did with the bags for the batteries.

Nice work.
Nice use of the terrible step motors! Atleast, if those are the same motors as mentioned on: thingiverse.com/thing:18678 (28BYJ-48 step motors)

Got any more info about the software used? (I couldn't find anything about it on your site)
