Robochallenge arena... they do all the uk champs so its there you want to use the full potential...

few tests from 540 when i first built it with magnets;

Driving verticle



Owning as a pusher... can see how it drove like it was on rails, and when other robots hit it, its like they drove into a brick wall... infact if i put the robot down on the floor... i physically couldnt push it sideways it had that much grip...also shows how the drive motors used to react to so much traction;



The next video shows how planted it made the robot when hitting into NST... doesnt budge at all... unfortunetly this is a good/bad thing... as all the force goes into making him fly off / straight into the body... which caused the armour to jam into the wheels;



The last video i found kinda wierd... it was due to the fact the magnet was so close to the drive motor i think (around 10mm away from a speed 900) or maybe it was so close to the esc...

Either way i had to ground out the magnets effect in the end as shown in the video by attaching a piece of hardox to the magnet, which in turn was held onto the removeable lid of the machine.... if i didnt do this id totally loose power to one side of the drive.



so in summary... make sure you balance out the size of your magnet to the power of your drive... if i built 540 again, id probably use a similar size magnet (50x50x20..BIG) but id go with a square wheel base with 4 off RS775 banebots on 16:1 with 75mm wheels or similar... would make for a pretty awesome pusher...

...but pushers are lame and still get owned by 720
