Re: Too much traction

1) Move the center wheels to change the wheelbase

2) Use a 1” wide wheel for 2 of the wheels which will reduce the friction (less wheel tread on the carpet)

3) Raise or lower the casters.

4) Install larger casters

5) Replace a wheel set for a pair of omni wheels

6) Change the wheel tread to lower friction type

7) Change the gear ratio of the drive

8) Install larger wheels on the left side of the robot (old dirt track stock car trick)

Number 8 is my personal fav cause it keeps in the spirit of the bases of this years game

1> Will work as long as the movement is to shorten the wheelbase
2> Reducing the wheel width will not gain much as Coefficient of friction has not changed
3> Will work, but be careful of reducing the contact of your wheels or you may go too far and end up with no traction on your center wheels (and end up hitting the walls).
4> Same as 3 with no adjustability
5> This wil work for turning ... but be careful if you do this with your wheels in the center of your bot as you may end up just swinging the rear out when you turn with little control at higher speeds
6> Will work, but will need some experimentation to find a good CoF wheelset
7> Will work as long as it's a slower gear ratio
8> Will make the bot difficult to drive straight.

Good luck, I'd suggest changing the center tires to ones with a lower CoF
