I have two identical box designs with EV3 bricks. When I upload the same programs to both, one moves about twice as fast as the other.
Is there a reason that this might be happening? Is there anything I can do to update it?

3Have you checked the batteries? Maybe one has almost-dead batteries?– Alexander O'MaraNov 20, 2017 at 19:45

I have fully charged both batteries and they are both reporting full batteries. I will try to swap out the batteries but right now it's not easily accessible from the design I've got, so I was just curious if this was expected or not.– LoriNov 20, 2017 at 19:59

1Can you post your program, or at least the part with the Move blocks?– David LechnerNov 20, 2017 at 20:11

1It's noticeable on a standard steering block - say at 75 power and going for a few rotations - on one brick that move may take a second, on the other, 2 seconds. i'll run and time it later today and post specific times, wheel diameters and rotations.– LoriNov 20, 2017 at 20:53

Are you sure the problem is with the ev3 bricks? Have you tried switching the motors? Maybe one is defective?– Phil B.Nov 21, 2017 at 13:18

Some possible reasons:
- A motor is defective
- One of the brick has lesser battery charge
- Firmware problem: make sure both bricks have latest firmware
