Hi DJ, what is the torque of the servos you used for arm movement on your Omnibot Project? I am starting to modify my bot and was wondering how strong I needed to make those. I have some that are 208oz/inch. Are those sufficient?
I can tell you that you'll most likely need to provide alternate power to the servos (i.e. direct 6 volts) rather than the Voltage regulator on the ez-b. The ez-b VR will do quite a bit of amps but the voltage is limitted to 5. And most strong torque servos like 6-6.5v
My omnibot is powered by a lead acid battery. It's the kind they use for alarms. Black and square. Kinda heavy, but powerful at 6v 4 amps. It's about 2 inches wide, 4 inches long and 4 inches high. I got it from a local battery supply shop we have. It was cheap too... I think $20
Just becareful and don't overcharge it... That acid is messy and dangerous stuff
