The details of the robot are described in final report EasyWheels_finalreport.pdf pdf

ReD (Remote Destroyer)

We have also another robot!

This robot is build by Ville Koivisto and Marko Niskanen (and advisor Petro Tamminen) at University of Helsinki / Dept. of Agrotechnology.

This robot was going to take part into competition for Task 1 and for freestyle. In freestyle task both robots work together. Unfortunately just before the competition start the electronics of this robot burned and it couldn't make into the competition at all.

Some facts:

  • standard Tamiya TXT-1 chassis
  • 4 wheel steering
  • two ultrasonic rangers
  • 2D compass
  • standard RC-servos
  • ATmega128 microcontroller
  • CMUcam3 embedded camera
  • mechanical weed destroyer
