I don't remember, I think I asked this question B-4. I got many conflicting answers.
I am building the Omni3000 robot. So far I have purchased an H-Bridge to control the left and right motors.
DO I need an H-Bridge for each ARM? some say yes and some say no.
Where do I go to find out for sure?
Why can't I simply run the motor in the shoulders and elbos , wrist and grippers by simply hooking up to a Digital port and using a separate battery for that heavy duty servo? I WILL have a regulator hooked up regulating it to a Maximum of 12vdc. When I hook the servo up directly, it blows the fuse on the EZB. But, THIS time I have it regulated and it's own 12volt supply. So, I don't understand why it wouldn't work this way. I have not tried it.
Ok, I think I remember someone saying "If it is a motor, it needs an Hbridge." "If it is a servo it does NOT need an HBridge."
Is this correct? Please advise.
