Update

ok so ive made some changes to the over all design. I was thinking about power so i thought about trains and then i thought about there front blade that they have and how much damage it could do if it crashed so i decided to add this modification to my robot or something similar to it. then i relised that it was an excellent anti-flipper device so i decided to keep it. other recent adds to the build include stregthend base for the wheels to add more traction. the next will probly be additional wheels at the back so that the main ones get even more traction

Update On Robot

Hey well ive decided to change my robot up and the design is a lil different now. So basicly it has had the front wheels removed for now because it failed it was too long for the arena not enough support in it to be effective. The other change i have made is to move the NXT brain block to above the wheels so it gets more traction. Im just going to go with free wheels for now at the front. With heaps of weight and support on the back wheels it will give it the pushing power needed to push the opposition out of the arena.

Ultimate Sumo Robots

Hi im building a Lego Mindstorm Robot for a robot tournament at school. Its pretty much a step by step progress of how its going. right then my idea have been a bulldozer type robot so it has the greater engine power over my competition as well but i want top keep it low so that the other robots who all have flipping type attachments are rendered ineffective. Thats pretty much all ive got so far.

P.S.
mine is the best in the class right now lol
