Re: Pushing Power?
Truck Town does not get pushed, they only allow their partners to assist their movement.
Though I find it odd that their best year ever (IRI win, national finalist) was a year where they had the same traction as everyone else...
Pushing is limited by either torque or traction. You really don't want to have a torque limited drivetrain (without shifting) as that can lead to extremely high current draws in pushing matches, and once you become traction limited you're "done" as far as increasing pushing force goes assuming an at weight robot. Ideal pushing force = high traction wheel + drivetrain gear ratio / motor combination to cause traction to be the limiting factor + 120 lbs.
Someone correct me if I'm wrong, because then I have a robot to tweak...
