Simple educational robot for learning how to use various sensors (light, line, distance...) with Arduino UNO.

It features the CRM-Shield and a four-CNY70 board for reading a line on the floor.


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

Good day sir can you provide me the code

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?

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 :)

Good day sir can you provide me the code

Yeah, that is another advantage of the Printbots: you can re-use the staff you already have ;-)

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

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
