Currently the only bots that are allowed to enter the competitions are the ones made from the kits.

This is to stop someone (I have asked) turning up with a mag powerhouse with tracks etc.

The project is designed to get kids into engineering and give them a practical use for physics and maths and it has been felt in the past that allowing any and all enter would detract from this.

Feel free to get in contact with the guild though. I dont speak for them.
