a = f/m
friction force = normal force * mu
normal force = mass * gravity
a = ( mass * gravity * mu ) / mass
a = mu * gravity
so, a 30lb robot and a 180lb robot should be able to change direction equally fast.
perhaps the 30lbs and the 180lbs were distributed differently, changing the moment of the center of gravity?
