This is probably the dumbest question I have asked but what is the black sheet that some people use on the back of their tilter’s called?
And what would be a good substitute for it if you don’t have access to it?
A lot of teams use lexan on the back of their trays.
But you can only use a certain amount:
Most people use polycarbonate(lexan) and any non-shattering plastic is allowed(R9). My team ordered this one from amazon:
Some teams use the flags from TP
Ok. How do you attach lexan to the back of your tray?
I thought of that but my team might not have enough flags.
A lot of people use zip ties as a better option, but you use screws and countersinks so they’re tucked in.
DO you atttaxh Lexan to the back of your tray with glue or something?
Robosource has black haircell-pattern ABS, which would be legal, too.
Actually you should start looking into how teams use lexan/polycarbonate. It is one of the most powerful resources we have, because its is one of the few items that has all of these wonderful features:
- Easily cut (hand saw, rotary saw, scroll saw, band saw, pure concentrated power of will)
- Easily drilled to put any screw or shaft anywhere you need it
- Basically a bearing as needed, like for supporting the outside of a cantilevered gear/wheel
- Low friction
- Very lightweight
- Can be permanently bent with heat, bent into an arc, or used as a bit of a leaf spring
- Can form the longest single structural component in the game The entire 24" sheet can fit diagonally in the 18"^3 space the robot occupies.
- Is clear (Looking at you vision sensor)
- and more
If you have a CNC router/engraver you can have the plastic cut to very low tolerances, but otherwise it is as useful to well funded teams as it is to poorly funded teams. It is a great equalizer.
All Hail Polycarbonate!
Any other alternatives?
If you are looking for a cheap back for your tray you can use zipties. Alternates to polycarbonate include ABS Plastic which is easier to cut(You can use a box knife with a straight edge to cut it).
