Pi Noon – the Robot vs Robot Duel


Time limit

3 minutes

Control method


Aim of the challenge

Robots will face off against each other in a non-destructive battle which will test the driving skills of the operator and the manoeuvrability of the robot. Robots will be armed with a pin on the end of a metal wire and must use this pin to burst balloons attached to the other robot.

The contests will take place inside an arena with a short wall around the edge to prevent robots from leaving the arena.

Special rules

Your robot must be able to hold a wire 2.5mm in diameter, 1cm off the ground. The method of attachment (shown below as the ‘fixing contraption’) can be done with something as simple as gaffer tape.

PLEASE NOTE: The wire must be attached either on the front or the back of your robot, in the centre. If it is on the front, nothing should be further forward than it. If it is on the back, nothing should be behind it. Please also note that the wire must remain as static as much as possible.

  • the wire will be about the weight of half a coat hanger
  • the wire will be provided to you on the day
  • the wire only needs to be on the robot during the duels in which you take part
  • if the wire falls off the robot then you will be allowed to re-attach it up to a maximum of 3 times.
  • if the wire falls off a 4th time, you will be judged to have lost the round.

In the event of neither robot winning outright after 3 minutes, the challenge judge will make a decision based on control and “aggression”.

Intentional damage to another robot will result in disqualification. It is up to the driver of each robot to ensure that no damage is caused.

The decision of the judge is final. Please don’t argue – remember, this is supposed to be fun.

Due to the number of competitors, some robots may receive a ‘bye’ to the next round. This will be at random and announced well in advance of the competition.


  • The winner of each round will be awarded 10 points.
  • 25 bonus points will be awarded to the winner of the grand final.
  • 5 points will be awarded as a result of a ‘bye’.
