@bigguy55100 Sounds reasonable :) somebody did go with tracks earlier in the year, and the only problem they had was a difference in forward thrust. In a head-to-head the wheeled robots tended to push the tracked robot back, so in terms of brute strength the tracks weren't as good as what one would expect.
The key to a good sumo robot is mostly in the ramp, although a low centre of gravity would surely be helpful.
@bigguy55100 I got them to experiment with gearing, but not all of those taking part could manage it the same. So for the sumo robots they all went straight drive from the motors and their focus was on building reliable frames for flipping and trying out different programs. I don't have the video but one of the kids developed a seeking program using the ultrasonic sensors: the robot would spin on the spot and then charge when it saw the other robot. Quite effective actually :)

@holyhell5050 oh yeah,did they go straight drive from the motors or did they lower the power and gear it down?

@darren1998s They did come up with some great ideas given the limited time they had to build their robots :)
