I just have a quick question. What kind of AC/DC adapter should I use? I just want to be sure not to break anything. Right now I am just working off of battery which dies off quickly some times. Thanks!
Learn section to the rescue!
He has 1 camera, and 3 HD servos. I read not to go past 12 volts, or below 2 volts. Any recommendations? This is my first robot ever.
BTW... The ezb4 itself is good from about 5V to 16V, but servos are generally good around 6V to 7.4V....
My answer for power supply is quite complicated but simple - I encourage direct battery power. BUT, if you need a power supply, there are digital switching options to choose. Make sure it's enough amperage according to that tutorial I linked to.
Motors are unpredictable for power consumption because they are electro-magnetic and there's a pile of variables that are pretty much unpredictable without a degree in physics
So pick a real high amperage digital switching supply for 6-7v and use it
Most of the transformers that you will find around the house are not digital switching. They use a transformer, which is two wounds of wire at a ratio which conducts electromagnetically across the two and produces a lower voltage in respect to the wire ratio. What that means is, those transformers literally only contain a spool of wire that lowers the input voltage by a pre-defined ratio. Then a simple Diode is used to flatten one line of the AC current to produce simulated DC current.
In short, a transformer power supply is not a great selection to power a robot. A digital switching power supply is the best option - specifically one with providing between 6 and 8 volts DC current at more than 6-8 amps for your application. If you add more servos, the number of amps will need to be increased.
If you want to get crazy, use a PC power supply
This is what you need... 7.5V Meanwell power supply

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.
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! :-( ...
Thanks a lot for the tip on the documentation!
On the one hand this solution is convenient and saves energy,
on the other - forced to buy only the EZ-B servos.
