I just started working with my ez-b v4 developers kit. I got the camera working and mounted it atop two hitec HS-422 servos to provide pan and tilt capability. The two servos work fine with the ez-b. The problem is when I connect just one of the servos that came with it the kit and make it move. I briefly hear the servo move and then the ez-b reboots every time. I don't have any load on these servos, just testing one. I am powering the ez-b with a regulated 12v 1.5 amp power supply. Could it be that the servos included in the v4 kit draw more power than the board can handle? If so, then why use them. I tried each of the four included servos (not the continuous rotation servos) one by one and each time the same result, reboot. Any thoughts. Suggestions. Advice?
Also I think those servos are 6 or 7 volt servos, 12 volts is way too much voltage. You will want to consider a dc to dc switching regulator to supply less voltage to your servos.
We are unable to assist you if you do not complete the Developers Kit Course on how to use your robot.
In short, here is a summary to help you with your problem:
1) do not use 12v to power servos. They will be damaged
2) 1.5 amps is not enough for powering the servos, so your EZ-B v4 is browning out due to lack of power. Please use the battery pack that is included, or review the tutorials on recommended ac/dc power adapter
3) review the Developer Kit Course and complete the lessons for the course. Specifically, you need to read this course: Powering Your EZ-B v4. Also complete the other courses that are relevant to the EZ-Robot Developers Kit
