[Chris] writes in to let us know about his latest animatronics tutorial, this time on robotic eyebrows! The tutorial takes us through the process of using a fairly simple PIC circuit to display ...

Stepper motors resemble servo motors in that both types are characterized by an ability to rotate a partial turn and then stop for any interval with or without holding torque. In addition, both motor ...

The MG995 servo motor is a workhorse in the world of robotics, RC vehicles, and automation. But what’s hidden inside its datasheet that makes it so reliable? Let’s peel back the layers of technical ...

Hobby servos are great, but they’re in many ways not ideal for robotic applications. The good news is that [Adam] brings the latest version of his ServoProject, providing off-the-shelf servos with ...

Making sense of servo couplings How does coupling selection affect productivity in today's automation environment? Bill Rexnord: Selecting couplings for Bill • Rexnord: Selecting couplings for servo ...
