Re: Programming Servo Motors

kellermana - we noticed the same thing last year. We used a servo to power a latch holding down our spring-loaded lifting mechanism, and it would always flinch when we enabled the robot. No idea why.

To get around it, we used a combination of things. First, we increased the amount of travel needed to open the latch - the servo had to turn further before it would release the mechanism. Next, we added some rubber bands to help hold the latch closed. It wasn't anything the servo couldn't overpower, but it was enough so the flinching didn't have much of an affect.

It would be awesome if someone on here knew how to fix it so the servo didn't do this... We aren't using any yet this year (but likely will with the minibot deployment), but know it will come up again in the future.
