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 ...

Crankshaft Change: With a piston fixed to its connecting rod and moving parallel to the cylinder walls, the Wiseman engine has lower friction than a conventional internal combustion engine. To convert ...

Rotary actuators produce oscillating power by rotating an output shaft through a fixed arc. They are compact, simple, and efficient. They produce high instantaneous torque in either direction and ...

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.) • ...
