The qualifying term "impel" implies that the robot taking possession would need to impart some force onto the ball, in a way beyond being just a stationary obstacle in the ball's path, and change its momentum, in order to qualify for an assist.

However, if a moving robot was heading toward intersecting with a rolling ball and then intentionally stopped itself right in the path of the ball so as to redirect the ball's momentum via only the ball's rebounding off the now stationary robot, I still think this could be considered an assist. Especially if that rebound improved the path of the ball for reaching the 3rd bot in the assist chain.

I seems to me the ability of judges to establish what in fact is a "desired location or path" might be a bit tricky to determine.
