Actually, you could get 15 points under the trial rules with no motors. Any inert object that fit in the robot square got the 15 points for not knocking down the scoring jugs under the trial rules. That WILL be changed for next year.

You could just deduct points for knocking them over, instead. Or you could just say that knocking them over is its own penalty.

From those who have seen these at competitions, what systems have you seen for building these? For example, Lego NXT or Vex or a custom built one?

yeah, we learned our lesson on that one when a team at the Ohio State tournament this year submitted an old shoe with a rolled up magazine stuck in it as their 'arm' and almost won the event because of this and the way the tiebreakers were setup.
what place did they get?
this wont fly when it is an actual event with more competition as it would be like submitting a mousetrap as your mission possible

Is the arm allowed to move the goals from their orriginal position, provided it doesn't tip them over, without any penalty?

With last year's published trial rules, there would be not penalties for doing that.

Are you allowed to use an adhesive to "grab" the objects, or must a physical grasping mechanism be used?

I've been reading up on programming and imagining design ideas, but I wouldn't suggest buying/building anything because the rules could be very different, though I've been playing with legos to test ideas

Do you know a programming software that is easy to use?
