A tale of two servos...
« on: September 08, 2010, 11:55:47 PM »
I couldn't think of an easy title.

I have two hitec HS-322HD servos. However, when I was trying to modify one for continuous rotation, I broke its circuit board. I ended up just ripping out all the electronics and now it is a two wire gearbox motor that works nicely. The other servo is unmodified and fine in and of itself. My question now, considering I want to use these two motors for two robot wheels, is whether I should just drive them differently (one with pwm, one with pwm for speed and an h-bridge), or strip down the good one and use h-bridges for both, or buy a new unmolested one and use it with the good one, leaving the DC "servo" for some other use.

I would rather not pay for another servo, but I also don't want to fall into any traps and I don't know much about all this robotics/electronics stuff. The only thing I feel sure of now is that it would be horrendous trying to get the servos working together properly if they were being driven by different mechanisms.

Thanks

Hi,

Consider the broken servo a learning expense and get a new one.
The broken servo will come in handy in some other project, or perhaps for something in your current build.

At least...  Now you know what not to do  ;D

A rather fast and fairly heavy robot with quite large wheels needs what? A lot of power?
Please remember...
Engineering is based on numbers - not adjectives

Yep, what Søren said.
