Drive dropping voltage of battery

Does anyone know how to stop the drive from dropping the voltage of the battery?

greetings,
This could be caused by several things. How long is your robot? If you have fairly grippy wheels, there may be too much force on the wheels to turn easily. However, going up the ramp shouldn't be too bad. a couple of things come to mind:
1. you have inefficiencies in the drivetrain (gearboxes aren't put together properly, lack of lube, chain/belt over tensioning, you get the idea)

2. Your gear ratio may be too large for the 10" wheels you are using. (please post again with this info)

3. Electrical resistance in you system. If you have a bad connection or wire and draw more current when going up the ramp or turning, the higher resistance will cause a significant voltage drop.

I think it's time to do some serious trouble shooting. let me know what you find out!
