Linear Actuators, Servos, and Motion Devices

By Tom Carroll    View Digital Edition  

In last month's column, I reviewed the typical rotary servos that we are so familiar with — those used as actuators for model airplane control surfaces or as drive motors for smaller tabletop robots. I also reviewed a few very large servos such as the Invenscience Torxis monster servos and a few tiny servos that weigh only a few grams each. This month, I would like to review a type of servo or actuator that not many of us ever implement into our robotic creations: linear servos and actuators.
