I’m currently trying to build a robot dog with Arduino Uno. It’s my first robotics project, but I’ve run into issues with the servo driver. I have 10 MSg90 servos connected to the driver but have been moving them one at a time so far.
When I try to move one of the legs, the servo connected to it shakes violently until I hold it steady to stop it. The servos were working for about a day, but when I tried again today, only the first programmed movements worked. After that, they stopped responding completely.
I had to switch to a new servo driver to get them working again, but the legs were still shaking. After testing, I think it may be a power issue. I’m not sure if it’s too much power or too little. I know servo shaking can happen from low power, but I also think too much power may have damaged the first driver.
My current setup: • Servo driver power port connected to a 6V 2000mAh Ni-CD battery • From the driver pins, I have GND, 5V, and analog pins connected
I also tried using a 5V 5A DC adapter, but nothing happened when using that. I don’t think the issue is wiring, so I’m not sure what to do next. Any ideas?
