so basically, any time I move my robot (say, to a standing position from its sitting down position when its off) it whites out the ezb. I have the ezb running at 12v and a splitter also running at 12v. Any ideas whats happening? It works until I move more than 2-3 dynamixels at once.
What is the amperage of your battery and what is the amperage rating of your servos?
the dynamixels can run from 9v-12v (im running twelve) and the v4 is currently hooked up to a wall socket (with a 12v plug for the splitter AND the ez-b)
So what is the power supply amperage rating that is plugged into the wall?
the splitter runs at 1800mA and the ez-b runs at 600mA.
I suspect that attempting to operate three servos at the same time is exceeding the amperage that the wall wort can provide.
I don't know which servos you're running but even the small ones use about 1 amp to operate.
an ideas on whar I can do to run them all at once?
1800mha wall outlet? I doubt it is able to provide 1800mha of hardware required current (i.e. motors). A wall outlet is usually made for transistor applications (i.e. computers, routers, etc) and not able to power motors - specifically when they are moving back and forth often, like a servo.
Switching Power Supply adapters are the only recommended wall outlet converter I can recommend.
PS, Dynamixels are pretty hungry for juice because they're tough little guys!
You would need to calculate the total amperage of all your servos and then either locate a 12 volt battery pack that can supply the needed amperage or as DJ mentioned a switching power supply with a amperage rating higher than what is needed to operate your robot.
