Yeah, that is another advantage of the Printbots: you can re-use the staff you already have ;-)
Haha I think it would be better to custom-desing one with smaller wheels to get all the torque from the motors :)

Will eventually try that :-P
I have uploaded all the source files. Hope you find them useful, though we will upload more detailed instructions and pictures.

Printing the wheels would be a better idea, for sure :D

This robot uses a lot of Pololu stuff because we designed it based on the components we already had. It could be much cheaper using other motors and an integrated castor ball :)

Instructions

Main features:
- Two Pololu micro-motors with Pololu wheels
- Pololu Ball caster
- Arduino UNO with CRM-Shield (which has L298 motor driver, two LDR sensors and one LED).
- Four-CNY70 board
- This shield and CNY70 boards are very likely to be used in other printbots :)
- 9V battery that connects to Arduino's power connector
- Main body is 3D printable, based on the MiniSkybot by Obijuan (http://www.thingiverse.com/thing:7989)

Designed in the "Club de Robótica-Mecatrónica, Universidad Autónoma de Madrid" by:
- Carlos García Saura
- Lucas Polo López

This wouldn't have been posible without help from:
- Juan González Gómez (Obijuan)
- Miguel Gargallo Vázquez
- Álvaro Pérez Ortega

great printbot. It would be great if you model also the wheels to be printed!!

Is the upper board home made? could you share the sources?

Add a scoop and that bot looks ready for mini-sumo
