I need help fixing a problem, the arm of the claw bot on Vex exp keeps dropping. I don’t know if it is because of the weight of the arm, I also don’t know if I need to fix it through coding.
Well, we need quite a few more details in order to help you. For example:
- Could you show us a picture of your claw or a video of it? (One overall view and one near where the motor shaft and gears are)
- Could you show us your code?
- Have you modified your clawbot in any way than the instructions instructed you to?
- What color cartridge are you using for your arm motor?
Sometimes problems like this happen because the motor is set to “coast,” when you might want it on “hold,” which makes the arm not fall.
This line of code should fix it: (c++)
Motor1.setStopping(hold);
or if you use block code:
if it doesn’t work, then it might be the cartridge

Try either what @Mr_Blockman said or make sure the motor is a red cartridge.
How far does the claw go up until it drops (all the way, partially, or barely any)?
or you can counter tension the weight using rubber bands, but don’t put too many or the arm will just stay up.
