Continuous Rotation Servo Tutorial

by ghostrider03z | December 14, 2013 | (12) Posted in How To

Hello all of the people in the world that happen to be reading this!

So there are pretty much hundreds of videos on youtube on how to make a servo rotate continuously, but they pretty much all suck. Either they don't speak English or they record with a potato and make no sense.

So the first step is to take the bad servo appart.

Then you are going to remove the gears and pop out the potentiometer.

De-solder the wires off the potentiometer

Take appart the good servo and locate the potentiometer

De-solder the wires off of the potentiometer but keep the good servo's potentiometer in the servo

Solder the wires coming from the good servo's board to the bad servos potentiometer you removed earlier

Remove that tab from the top gear of the good servo

Put it all back together, set it neutral and bam! You have a continuous rotation servo!

Also I picked up a Zoom H1 microphone so the audio is better, if you want a video on that a bit I could do that also.

Let me know if you want to see a rover video. I hope you found this useful or a good refrence.

Yea, since I just got it built really recently I haven't had much time to play with it but what I actually plan to do is put some fpv gear on it, sit in my garage or house and drive it outside on some trails in the snow. It should be fun and I made some small test trails and it goes over it really nice! Im amazed that it doesnt sink through the snow since it is really fluffy, considering the thing is so small and carrying a battery and full gopro when I did the tests!

Really? wow, it doesn't really look like it would do that well especially on fluff... Anyway awaiting vids! Also, do you know how much weight it will carry?

Well, I should correct myself. carved out paths in the snow yesterday and they drifted in a bit again overnight and it easily crawls over that. When you say how much it can carry, do you mean how much it can carry before the servos want to blow up?

Yes, I guess. Like how much weight when you want it to live for more than one run.

Ok, I'll test it tomorrow after school. Or maybe tonight if I feel like it.

Lol sorry for the reply as slow as this rover. I just tested it and it was able to carry a 1600mah 3s and about 20oz extra, still running nicely. With that much weight though, the servos probably wouldn't last very long.

Ok, so basically keep it light then? Do you think the FPV thing will work after all or will you have to keep thinking and improving?

Ok, that sounds bad. I put a 3 pound weight on and it still drove, it was just pretty bogged down. 20oz max PAYLOAD is a light estimate. FPV, Gopro, and fpv tx wont weight nearly that much. But the heavier it is, the crustier the snow has to be to hold it. I'm still going to put fpv on it, it wont even notice it. Its just finding time to do it for me, pretty much as soon as i get home from school, its dark.

Awsome idea!!!! And so simple !! I been wanting to build an F-14 Fighter with sweeping wings . My problem was getting an internal moving battery tray to move accordingly with the wings for proper CG. This will do great for the job! Thanks for the Idea.
