Rolling-ring drives are friction drives that convert the constant rotary motion of a plain shaft into a traversing action that moves an attached carriage. Used in positioning and reciprocating ...
An achromatic linear polarization rotator based on a tandem-2Ï•-twisted nematic liquid crystal cell (tandem-2Ï•-TNLC cell, where 2Ï• represents the total twisted angle) is theoretically analyzed 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.) • ...
A cam is a rotating piece that converts rotary motion into reciprocating motion in the follower. Think of it like a spinning shape pushing something up and down. Eccentric/off centre cam: this is the ...
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.
OTTO is an open-source automated liquid handler that can be fabricated at a cost of $1,500 using off-the-shelf and 3D-printable parts as an alternative to commercial devices. Open-source approaches ...
Monitoring takes the form of sensors and intelligent devices connected to a digital processor. These monitored values are used for computing and then controlling some sort of real-world action. Many ...
