Tighter spacing=more friction=more strain on your motors
Oh yah that’s a problem…
While there are many I would have to say the one that tops the charts is me in 8th grade going to a tournament with a robot that had no bearings on it. When asked about it, “what are those for?”
facepalm
In January, me and my team made a double flywheel in two hours, and tried to mount it using standoffs and long screws of different heights to get an angle. Obviously, the bot couldn’t shoot much more than 2 feet downwards and we still managed to be finalists.
I don’t exactly see your problem here… did you have a low gearing or something because you should be able to shoot 2 feet with no angle at all.
Perfect example of how the vex match making works… 
Fortunately the RobotC autosave is really primitive and you can find all the previous saves in the Recycle Bin.
I forgot to mention that my teammate downloaded a program that would make the wheels stop every 2 seconds for about 0.5 seconds, which was why we couldn’t shoot more than two feet.
Edit: Again, I forgot to mention that the program and flywheel were built the night before the competition, and the mounting was done at 5 AM before hand.
Accidentally set flywheel to reverse on autonomous… a ball even hit me 
unfortunately I forgot what division we were in. I agree it was not bad but making it fit within the 18x18x18 box was quite a sight.
Leaving a battery on our robot, unplugged, only to have it fall not the path to our car. I had to walk back to the pit area to retrieve a jacket, and saw a battery that resembled ours, and I was devastated when I saw it was super ripped and beat up from people and vehicles running over it.
Last year in Skyrise, we had a robot with a flip out skyrise claw. I forgot about the flipping out part. I am holding the robot during inspection, and the inspector turns on the autonomous and I get whacked in the face… I could have sworn I got a black eye.
Stripped every single screwdriver, yay me.
Letting all of the chargers charge already full batteries on fast for an hour. Welp… There goes or robot and batteries.
Made flywheels controlled by aceelerometer. You press a button and the angle of the remote is the distance of the ball. Seems good right? Well think again. Put remote aiming up which makes flywheels at full speed, then jolt the remote facing down, absolutely killing all 4 motors.
On a different subject, does anyone know how to program the accelerometer that is built into the controllers in easyC?
Yes, here is an example I built, it might not be properly correct, but I will try. It is supposed to be for driving the VEX Clawbot using the accelerometers.
task(main);
{
while(1==1)
{
motor[leftmotor] = vexRT[AccelY] + vexRT[AccelX];
motor[rightmotor] = vexRT[AccelY] - vexRT[AccelX];
}
}
Do you know easyC? I don’t know robotC
