is 2 amp in current low or much for the ezbv4? i found the guy whit the lazers my idea was to use 4 big servo's from here.for moving the head up&down. mount the camera on the left choulder (predator) and ontop of the camera, 3 lazers,they are 6 volt one red two blue.i will use the blue just, for tracking red baloons,ones the robot spotted blue goes out and red goed on. thats 2 amps for one lazer x3 is 6 amps just gessing
alan magi smoke for the lazer or ezbv4? whats a tip120 circuit?

oh boy in the video it looked all simpel
Nomad,
Blue smoke from Lasers, not EZ-B. They will burn up if given too much voltage.
A TIP120 (or 122) is a circuit that uses a transistor to switch the ground on and off on a higher voltage circuit using the low voltage signal wire on the EZ-B. They are so cheap and easy to make, you can't buy a commercially made one. An Arduino Relay board would also work if you don't want to make a circuit.
Here is a link to how to make a TIP120 circuit. Just a transistor, a resistor, and some wire. https://synthiam.com/Community/Questions/3050 (the tutorial also has header pins and strip board, but I have made them "inline" without the header and strip board. Just laid it out on a breadboard first to make sure I had everything right.

thank you
Not just the tracing but the incoming power diode is rated at 5 amps , so beyond that magic smoke appears.
