Re: Grabbing 4 Bins from the step in Auto

Grabbing recycling containers off the step in auto is not a primary goal of ours. However, we will have some capability there... We almost certainly will be able to grab one and, with a little time, might have a good play for a second. Basically, we'll be able to grab any game piece we want, but, to get to those on the step, we'll need to push landfill totes out of the way. Just how much will we be able to do in auto will be better known once the robot is finished.

As the mentor who leads scouting and tactics, I would be watching robots with long grabbing arms like this very closely. It seems to me that the level of precision necessary to be successful would make the construction of such a robot very, very difficult. Moreover, there would be some considerable risks involved in its usage:
* If something is ever-so-slightly misaligned, I could see those long arms knocking the RC's off the step in the wrong direction.
* Again, with a misalignment, should an arm reach too far and contact another robot, it could lead to a red card. (Ref discretion - a hook reaching too far could be seen as "strategic" or "egregious" if it gives a an advantage or affects the other robot.
* There would certainly be concerns with center-of-gravity. How would the robot react if another robot were to grab the same container at (or just after) your robot and pull? Could your robot fall over?

All that said, such a robot could be the ideal partner for ours... I would be watching such a robot very, very closely through preliminary rounds and wanting to know: Did they do it so well that it is the ultimate partner? or, did they miss a step, causing it to be a high risk to be a veritable disaster?
