I don't see how sharing would give away any potential competitive advantage since it has no effect on the race to the target... and see great advantage to helping a fast minibot that could be your alliance partner stay intact enough to benefit your team as well...

When a DC motor backdrives, it acts like a generator and generates electricity. To slow the backdrive, add a load onto the system by isolating the motor from the battery and shorting the two motor leads together after the Minibot reaches the top of the pole. The Minibot will then roll down the pole slowly.
