Uh, shouldn't a 1:3 gear ratio make the output rpm greater than 12600, assuming 4200rpm at the output shaft of the motor?

Actually you have them reversed. A three to one gear ratio would triple the speed of the robot and a one to three gear ratio would increase the torque of the robot by a factor of three. I believe your confusing the speed ratio and the torque ratio which simply enough are inverses of each other.
