Hello, all. In my old EZ-B version 3 of the robot, I used double power. Small power proper for EZ-board = + 7.4V 2800mAh & for the rest "power units: 6 servo, Cam, MP3, Light, 6 sensores" = + 11.1V 4000mAh + step-down DC-DC regulator +5V 6000mA. What about new V4? I'm trying to find the technical details about the new V4 robot. Correct Supply voltage, current consumption in rest (hold) mode, the maximum current consumption, etc. Where can I find this information? Another option is very important to me: What the average range of wireless communication in the home and outdoors?

Thanks for your attention.

Wifi has many options to extend it's range miles, along with being able to be routed over wired networks.

Dir DJ Sures, you write about your power servo 7.4V! Does this not reduce the service life of engines? I thought that this is the maximum voltage for small servo is 6V? (how I lagged behind you for two years! :-( ...

Hello, CochranRobotics! Thanks a lot for the tip on the documentation!

The HD servos are made to run at 7.4V. If you took a servo that was made to run at 6V and ran it at 7.4V, yes, you would reduce the life of the servo. These are not 6V servos running at 7.4V though. They are made to run at 7.4V. I have many of these running for about a year and a half of normal use at 7.4V without any issue.

Thanks for clarifying. On the one hand this solution is convenient and saves energy, on the other - forced to buy only the EZ-B servos.

You don't have to run the EZ-B from 7.4V. It can be run from 6V which would allow you to then use anyone's servos. You could also regulate the power off of each of the servo wires if you wanted to go 6V. Either way, your not locked into buying servos from EZ-Robot. This is a convenience that helped them to make their revolution robots without having to regulate power inline for them to work well.

Thanks for clarifying, CochranRobotics!
