Hey guys, I can’t quite make a mechanism that can lift the polycarbonate sheet up and down according to what me and my team want so we need some help with that.
Welcome to the forums!
Okay. We need a little more information. Though. What are you trying to do? Pictures will help too.
I am confused is it Iq or V5
It sounds like V5.
If pictures weren’t available, could you describe exactly what this means?
If I had to guess, I’d say he’s talking about the top of the hood deploying at the start of the match.
Do you think you could provide some pictures so we can better understand what you are trying to do?
I would like to jump on this topic just to ask a question. Can I use the polycarbonate sheets to build the back and hood for our bot? It says a limited amount in the rule book but this would be the back attached to 1x5 structure and the hood attached with a hinge. In other words is that everyone else is using for their hoodbot?
Mostly, I think. Other people will use rubber band rollers on the back, too, or you can use plate too, but Polycarbonate does well. Just make sure you are only using the amount you are limited too!
I would say to drill holes in the edges of the sheet based on where you want it (the holes should be slightly larger than the screw you want to use) and screw the sheet into the robot
Where would you want the polycarbonate sheet to be?
You can use it anywhere as long as the total amount of non-shattering plastic isn’t larger then the size limit (as described in the manual). I personally have seen a lot of teams using it for their hoods this year, as have teams in years past (NBN & TP).
Yes, with the non-shattering plastic I would say “If it feels like a lot, it might be a lot”, essentially being pretty darn big.
Here is the exact rule:
(R10) A limited amount of custom plastic is allowed. Robots may use non-shattering plastic from the
following list; polycarbonate (Lexan), acetal monopolymer (Delrin), acetal copolymer (Acetron GP), POM
(acetal), ABS, PEEK, PET, HDPE, LDPE, Nylon (all grades), Polypropylene, FEP; as cut from a single 12” x
24” sheet up to 0.070” thick.
a. Shattering plastic, such as PMMA (also called Plexiglass, Acrylic, or Perspex), is prohibited.
b. Plastic may be mechanically altered by cutting, drilling, bending etc. It cannot be chemically treated,
melted, or cast. Heating polycarbonate to aid in bending is acceptable.
It can go anywhere on the robot as long as it starts within the sizing requirements.
