A slider-crank mechanism is a typical design which converts rotary motion into linear motion. It is achieved by connecting a slider and a crank with a rod. Figure A depicts a mechanism utilized as a ...

RC servos are handy when you need to rotate something. You can even modify them to rotate continuously if that’s what you need. However, [Roger Rabbit] needed linear motion, but wanted the simple ...

Roller-pinion systems are a better option than rack and pinions where accuracy and a minimum of friction are important. • Roller pinions can provide accurate positioning up to ±30 µm (±0.00118 in.) • ...

Stepper motor linear actuators (SMLAs) combine a stepper motor, precision lead screw and nut in one compact envelope, providing a highly configurable, customizable and robust system for linear motion.
