Now that I think about it, this is an actually pretty **** good robot on paper. Historically, a linkage is the fastest hanging system without using pure elastic. A scoop, so far has been the best intake this season. The shooting capabilities has room for improvement without drastically changing the design. The lift also doesn’t sacrifice control of the game pieces, but fully exploits the power behind the rubberbands. The drive train capabilities is somewhere between acceptable and perfect, if not negligible. Maintenance could be a area of improvement, but it’s not critical in a robot’s initial performance
This is robotics, not English class. 
Thank you. Jonathan should know because he was born in London…
Thanks! We spent a lot of time thinking about the design before actually building it.
It looks like that if the arm is down, it gives a constant power.
task intake() {
while(true) {
if(vexRT[Btn5U]) {
if(SensorValue[shoot]) {
setLiftSpeed(-40);
wait1Msec(500);
} else {
while(!SensorValue[shoot]) {
setLiftSpeed(127);
wait1Msec(25);
}
}
} else if(vexRT[Btn5D]) {
setLiftSpeed(127);
wait1Msec(700);
setLiftSpeed(0);
} else if(vexRT[Btn7U]) {
setLiftSpeed(-50);
} else if(vexRT[Btn8U]) {
while(!SensorValue[lift]) {
setLiftSpeed(-127);
wait1Msec(25);
}
} else if(SensorValue[lift]) {
setLiftSpeed(0);
} else {
setLiftSpeed(10);
}
}
}
Quite late here, but I never actually deployed the code in that repo. For all I know it might not work at all. I wasn’t the primary programmer but I wanted to simplify the code that was written for the bot and make it more readable. I may have missed something as I tend to make a lot of mistakes the first time around and fix everything later.
How did you guys tighten the standoffs that connect toe ach other on your intake? Ours come loose after practice all the time, even though we tighten them with two wrenches to turn the standoffs against each other. The wrenches even cause the standoffs to strip a lot but they get loose anyway…
use lock tight
Use nylon washers inbetween the connecting standoffs.
i have put washer in between mine, but the standoffs till came loose, locktighte is the best option
@skittles lover @vex2.0 Thanks guys.
What was used to create the poly-carb hooks?
Not to be cute but legal .070 poly-carbonate (lexan).
I meant what tools to cut and shape it.
We use tin snips to cut a lot of our thinner lexan and then file it down so it doesn’t have any rough edges.
I see that you guys are using your own rubber bands.
Our team wanted to test out a catapult design, but we don’t have any #64 VEX rubber bands, and the #32s weren’t strong enough.
We considered using latex tubing, but needing to tie them into loops creates variations in catapult strength when we switch them out, so we wanted actual bands that were strong.
We plan to go buy some rubber bands locally soon; Anyone know anything we should watch out for? I know in the manual says products that are identical in all ways except for color are permissible, but the website doesn’t say much about the rubber bands outside of their dimensions and that they are latex-free synthetic rubber.
Any tips would be greatly appreciated!

Can you guys release a video of shooting the cubes? You said that you could shoot two stars or a cube from closer up to the fence, but you only showed the two stars…
