Robot Losing Communication when strafing right

[Joe Ross]

I suspect that your digital sidecar isn't properly powered. It gets some power through the DB-37 cable, but not enough to send a full speed PWM to 4 motors. Assuming that your right motors are inverted in code, a left turn is minimum PWM to all motors and a right turn is full PWM to all motors.

Disconnect the DB-37 cable from the digital sidecar and make sure that all 3 power LEDs are brightly lit.

Have you solved your mechanical problems from your previous thread?

Okay, Tuesdays and Thursdays are days left for labor intensive homework so no we have not solved the mechanical issues yet. The mechanical one is harder to fix than the wiring one so we will try the wiring tomorrow after school gets out. Thank you!

As to luckof13, yes the voltage regulator is correct, the voltage drops from ~12.43ish to ~11.5ish then spikes back up to the original voltage.

All 3 LEDs are powered on.
I wouldn't say that losing communication is the best way to describe it. It just stops moving. The driver station is all green and the robot is all green. Jaguars are blinking. It doesn't take any inputs after it "dies". We need to disable teleop and then reenable teleop to get it to take inputs. The Dashboard is showing that the joystick is still giving an input after the "death".

perhaps your code is crashing ? check netconsole and try to find a minimal test case.

I wouldn't know why the code would be crashing? We loaded a WPILib built mecanum program. I'll check later.
Would I need to use a filter capacitor or two to get rid of glitches if that's the case?

Well the problem was that we inverted the motors mechanically and it hurt the robotdrive.
We inverted it in code and it works fine.
