@squirrelman777 Try running it with new motor controllers. Whenever we have a problem with motors not behaving we always try that first. Over the past two years, motor controllers have caused our robots to attack us and to drive away.
We really can't change motor controllers as vex has stopped shipping them and we only have around 12 all of which are on the bot.
@goofnrox Using a power expander for drive motors is just fine, just not ALL of the drive motors.
OP didn't specify if there is an expander on the robot. If there is the best wiring configuration will be to have two motors on each PTC channel. Otherwise split the motors evenly between the two PTCs in the cortex.
Cortex 1-5 is one channel
Cortex 6-10 is one channel
Expander is one channel
@AryanG how is the bot wired?
We do have a power expander specifically for the drive but it is wired on the correct cortex channels to split them between the PTC's on the cortex.
@Rick TYler 1. Too much friction
- Over-geared <and/or> overweight
- Bad motor controller
- Bad motor
- Chains that are too tight (leads to high friction (see #1)
- Other weird stuff (motor not plugged in)
Listed in order of occurrence after watching VEX robots for 12 years.
We have checked through 1,5 and 6 we are strongly suspecting it to be bad motors or MC23's. We shouldn't be too overweight as the bot is approximately the same weight as a bot with a mogo on it from itz.
