This is our end product. The robot will have to separate coloured pens added to the motor which acts like a see-saw. The robot will detect yellow or red coloured cards and this will form the robot to react and zigzag acting as a representation of a touch rugby player. The characteristics of this robot seems to always rely on 2 wheels and a analog type, that has a ball in the centre that deceases the friction and increases the speed/rotation of the robot.
