Per Gary V. "Doesn't appear to be legal per <G27> - it would be herding while in possession of another ball."

Per Definitions: HERDING: Controlling the position and movement of a TRACKBALL while the TRACKBALL is not supported by any ROBOT (i.e. supported by the TRACK or other TRACKBALLS) shall beconsidered HERDING. Both continuous and intermittent contact between the ROBOT and
TRACKBALL are permissible methods of HERDING. E.g. bumping, plowing or dribbling a TRACKBALL around the TRACK are all considered forms of HERDING.

I am still debating this one. "Controlling the position and movement" Hiting a trackball with another trackball (in your possession), my question about this is whether or not I could really have any control over where the hit trackball would end up, no doubt I would be causing the trackball to move from a resting position, this makes me think I should agree with the conclusion quoted. "Both continuous and intermitant contact" makes me think you have to hit it at least twice to be considered herding and that one hit would be OK.

How about number four try for legal means: why not catapult a trackball from your less than six foot high robot, at most it would be considered herding?
