M.Krass - yes, you have the right idea. You could also drop the voltage (PWM output) to the high torque motor when the robot is going fast, or even stop it completely - since its not engaged, its only spinning and wasting power.

The thing I like about this idea the most, you could do this without the oneway clutch (ratchet) with gears and/or chain drive , and to make it a two speed self shifting tranny, all you need to add is one moving part - the little spring loaded cog level thingy.

One extra moving part - you cant get any simplier than that! :c)
