H-Bridge with pot feedback, who makes it

Dec 03, 2004 6 Replies

Can some kind soul refresh me memory.



I know I have seen an off-the-shelf H-Bridge board that used a simple potentiometer for feedback and a standard RC servo pulse train for input. The idea was to convert any DC gearhead motor to act like an RC servo. I thought it was Active Robotics but I don't see it on their site. But now that I want one I can't find it again.



Does anyone know who makes this thing?



Any help gratefully received.

Randy, maybe you're thinking of the Bully series from Vantec?

I found this controller which would do the trick (36V 5A)

however, I do also remember seeing a different controller on one of the robotics web site like Active ot RobotStore, which doesn't seem to be there anymore.

Contact me by email if you want/need something different this.

Hope this helps.

Interesting, but not the one I am thinking of. This was a simple board and rated much lower, maybe 5 amps.

Thanks very much for the reply however, this is an interesting looking device and I will definitely file it for future reference.

Thanks again...

Lynxmotion sells the servo guts from the big quarter scale RC servos. You would only need to hook up a feedback pot to it and run the 1ms to 2ms servo pulses into it and you have the setup working like what you are talking about. These are rated at 2 amps. It is the single H-bridge controller on their website.
