I’ve got 7 VEX IQ motors at home. 6 of them are about 5 years old and I don’t know about the other because I got it from a coach. For some reason 6 of the motors are slow and lack power, while one is much faster and powerful. For example, I’ve tried building robots on YouTube before and for the drive train I use the same ratios and they refuse to turn, or move very slow unless I use the good motor. Do I need to buy 5 new motors (they’re expensive!) or is there anything else I can do? Please help.
have you checked the friction on the setup? idk much about vex iq but friction can always play a role in things like power loss
Yes, the drivetrain isn’t the problem I’ve checked it many times. It’s just the motors, one moves way faster than the other 6.
if it’s not a mechanical problem, and not a problem with your code
you’ll likely need to just buy new motors unless you can fix the current ones. they sound kinda dead lol
You’re probably right. Just thought I’d post something to make sure because I’m reluctant to spend money on motors. 5 motors is over $100.
just wait till vrc lol it gets even worse
$40 per + extra cartridges
Yikes. I’m doing VRC next year
But by then I won’t have to pay for things. I’m doing my own team this year with my brother because of coronavirus.
robotics is not a cheap hobby unfortunately
If those are non-competition motors you can consider repairing by cleaning and re-lubricating them yourself. This topic talks about opening IQ smartmotors:
