Is assisting the robot arm with a vacumn legal?

Is it legal to use a vacumn in the robot arm?

As long as your vacuum is powered by a legal FRC motor and the rest of your mechanism complies with the FRC 2011 Manual.

I remember a lot of vacuums back in the days of Overdrive 2008; they were cool, but pretty ineffective.

True, but think of team 25’s vacuum last year. It was a highly effective means of holding on to the soccer ball. All in all, however, I think that a vacuum takes a lot of tweaking when compared to a “grabber” that can to the same thing.

Indeed, and those soccer balls were a hell of a lot lighter than that darn track ball.

I’m fortunate enough to have one in my 19 year collection of game pieces.

I think the most common issue with engineering is that it makes people aim to produce more creative methods instead of using effective methods. Innovation is a fantastic tool for solving problems, but sometimes your problems have already been solved in a more efficient way.

What does this method add in functionality or approach? If it doesn’t alter the functionality and is only there to be cool, then it’s a waste of time and energy.

It is a cool concept, but don’t let cool factor diminish functionality.

Legal, yes, as long as it follows the specifications. However, keep some stuff in mind when dealing with suction of any sort:

  1. The surface of suction needs to be fairly flat, otherwise there’s no chance of getting a good seal.

  2. The amount of suction required could be quite a bit.

  3. The power requirement would be great. Remember, you have to carry the tube across the length of the field before you can score.

So, yes, it’d be cool to have a vacuum robot. But our team found that there were just too many issues to justify it.

When you let go of the tube, a vacuum is less likely to get caught in it.

Well if you can make the outcome just as efficient as a mechanical counterpart then the answer to my previous question is yes, it does increase functionality/efficiency.

I’m not trying to hinder any ideas from developing and flourishing further - I just wanted to give some advice. Our team has a bad habit of getting stuck on improving a particular idea - so much so that we do unnecessary things and waste time.

Right now our team is stuck between claw/rollers, vacuum/suction cup, and a pincher for the grabbing mechanism. Have any teams prototyped any of these yet?
