Stepper motor linear actuators provide thrust along a linear axis but cannot tolerate side loading. Supplemental guidance is needed to protect against external forces impacting the linear motion of ...

The current state of robotics, 3D printers, and CNC machines means any shade tree roboticist has the means to make anything move. Do you want a robotic arm? There are a dozen designs already available ...

A linear actuator combines linear-motion components and a linear shaft motor (direct drive) in one assembly. Such an actuator creates motion in a straight line, in contrast to the circular motion of a ...

Linear actuators are useful things, moving things in straight lines rather than annoying circles like so many motors. [Retsetman] recently built a linear servo actuator of his own design with accurate ...
