Re: Opinion on Legality of Sharp Components
Well its a cheese grater so just running your finger on it not necessarily, while its rotating or if you pushed hard most likely.
My question is how is this different from a sprocket and chain? If I push hard or put my finger in there while moving? I am not sure I see the difference. A lot of things on robots can hurt and cut if that's the intention. That said I am looking for opinions so I do appreciate the view point. Cant ask honest opinions and then debate them away. Thanks. |

Re: Opinion on Legality of Sharp Components
Since [I04] implies that team-supplied ropes are included in the official definition of ROPE, [G15-H] may mean teams may not damage their own ropes.
Here is my Q&A question on that relationship. In hindsight it could have been better-worded, but I'd already spent a day trying to figure out how to say it in order to prevent the "the LRI will judge it..." response. It effectively calls into question what the difference between damage and wear & tear is for ropes - which applies in any climber using an abrasive design for capture. It came up for us, so I had to ask. Last edited by JesseK : 25-01-2017 at 10:12. |

Re: Opinion on Legality of Sharp Components
Quote:
When we look for sharp edges, it isn't just a cursory glance. We look for edges that could cause damage in the areas where team members are likely to put their hands - near the main breaker, under the robot where they pick it up from, access areas to mechanisms, etc. We also look for pinch points in areas where hands are likely to be. To me, a rotating cheese grater on a robot just sounds dangerous. We've all seen times in the pits where people jump back because they weren't expecting the robot to move, or where a robot jumps off it's blocks and starts driving away before someone can hit the spacebar to stop it. Accidents happen, and I, for one, wouldn't want an item like this to turn into an accident for one of my students. I'm sure you guys can find a better way to climb over the next couple of weeks if you put your minds to it! |

Re: Opinion on Legality of Sharp Components
I've been advocating for our team to have some kind of lock-out to keep the winch with robe grabbing tines from moving, unless specifically being used for testing.

Re: Opinion on Legality of Sharp Components
Regardless of how legal it ends up being or what solution you end up going with, I would definitely suggest some kind of guard to place on this kind of mechanism as a "remove before flight" sort of thing - say a piece of lexan held on with Velcro you pull off as you're leaving the field. It couldn't hurt with arguments you may find yourself in as to the safety of your mechanism, at the very least.

Re: Opinion on Legality of Sharp Components
I did see the Q&A. It seems like most are in agreement. Its not outright illegal but not the best idea. Like I said we were debating this and came to the same conclusion. We have other ideas and designs. Thanks for the feeds back from all. Its good to get a general consensus to know where you stand.
