Re: Door lock actuator shift?

We've been experimenting with door lock actuators for a couple of years now but haven't had one on the competition robot yet. It's hard to resist a 3/4" throw electric linear actuator for $5.

They definitely provide enough force for shifting (in our experience) but tolerate being stalled about as much as a RS-550, meaning not well. We have not tried detecting stall and backing off on the command to maintain position yet. These actuators backdrive easily and even the accordion boot over the shaft is enough to return the throw to roughly center position.
