Thanks for the comments - but just so there's no confusion, the Workshop 3D
RCX Challenge isn't sponsored or run by SMART. I'll make sure that Ray sees
your comments.
By the way, I also had a blast at the last competition!

I'm not sure that changing the pucks to balls will completely solve the
problem that you see. First of all, getting a hundred balls (be they
ping-pong balls which you could easily buy in large quantities, or LEGO's
yellow foam ones, which as far as I know only come two per set, and there's
a lot of other bricks you're paying for in there!) would be quite expensive.
The pucks are already available.
But secondly, balls roll easily, and I think we'd see the majority of robots
entered would be simple herders or harvesters that just push the balls up an
incline if they needed to be off the ground.
I'm not speaking for Workshop 3D or Ray, but I think the idea for this
particular event was supposed to be that it is the toughest one to build a
robot for. The line tracking and sumo events are accessible to most people,
but puck gathering was supposed to be the complex event. And there *should*
be an event to really challenge the competitors. If the same event is used
again, I wouldn't at all be surprised if the rules are changed to involve
picking the pucks off the floor next time.
Anyway, good comments. I look forward to seeing you at the next Workshop 3D
RCX Challenge, and perhaps the SMART meeting on this Saturday.
