Field Robot Event 2009
EasyWheels robot took part into Field Robot Event 2009 in Wageningen. It performed fairly well, the result was in 2nd place in overall competition and 2nd place in freestyle. As a freestyle the team demonstrated quick changing of axel module in a pitstop.
EasyWheels 2010 took part in Field Robot Event 2010, with a completely new software and refurbished electronics.
The team consists of students from two universities at Helsinki area. The team has six members from Helsinki University of Technology, of whom three are studying Automation and Systems Technology (TKK/AS), and three Mechanical Engineering (TKK/K). The team has also two students from University of Helsinki (UH), Department of Agrotechnology.

The details of the robot are described in final report EasyWheels_finalreport.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.
- standard Tamiya TXT-1 chassis
- 4 wheel steering
- two ultrasonic rangers
- 2D compass
- standard RC-servos
- ATmega128 microcontroller
- CMUcam3 embedded camera
- mechanical weed destroyer
