Ok,  what about this?  To make the robot roll a ball that
totally encases it:

Make the wheels on the robot permanently attach to the ball.
Like have two wheels on the robot, bigger than the robot so 
that the robot can spinn freely if the wheels are held stationary.
Then make the robot quite heavy so that the motors can't generate
enough torque to spin the robot.  Then the robot would spin
the ball instead.

So,  will this work?
