6 volt

Power Screwdriver Motor

So I bought a few power screwdrivers for the main drive motors for my new robot project. I have started creating a rocker bogie suspension system out of PVC pipe. This suspension will require 6 drive motors. The power screwdrivers run on 4 AA batteries. So the motors are 6 volt. By browsing the interwebs I figured out that one AA battery supplies about 2.4A. So I figured that each motor would require 9.6A. But since I have 6 motors I would need 57.6A. This would require a huge SLA which would weigh about 20lbs and cost around $100.

Zen Master

I'm building a robot with many different voltages here.

I have managed to avoid voltage regulation by cheating, I run the motors that are rated for 4.5 volts at 6 volts from a RC NiCd battery, and I use an RC Electronic Speed Controller that can give 5 volts to the RC receiver, the wireless camera and the Picaxe. I feared that this might be a problem and turned to the all knowing LMR forums for help. And help I got...
