“Building a Lower-power Linear Actuator with Arduino: quite a few people have asked me about scaling down openDog to make it lighter and cheaper, so I thought I’d discuss the options in this ...

Most electromagnetic actuators are rotating motors, or some variation on the theme, like servos. However, it’s possible to do linear actuation with electomagnetics, too. [Adrian Perez ...

The end result is a completely sealed linear actuator that withstands dirt, debris, and moisture. The actuator has a rear enclosure that houses and seals the lead screw and bearing assembly, a bellows ...
