If the voltage regulator built into the ez-b works well I see no connection with the battery, for higher voltage just a little warmer but not the control panel of servo operation changed the battery because I do not understand.

Have you followed the modified movement tutorial? Click the Tutorials button from the top of this webpage. The modified servos connect to two ports, and the Movement Panel does the rest

thanks I just checked and it was a wireing error. It work fine now. I will from now on check my wireing before I post a question. now that is comeplete I can finally post my robot. But don't expect much. my very first robot I made wa destroyed by my dog. even though I didn't like that I jut couldn't be mad at him. The very first robot was made by chopsticks hot glued to eachother to make a wall. it was a very zen like robot but since it is nowdestroyed I have to make it again using the left over chopsticks. It's not much I know but it turned into my friend.

Awesome! All robots are amazing. There's no such thing as a boring robot

Actually I'd have to say its the highlight of my day when someone posts a robot they made.
