This is one of the most commonly used robots in industry today (many examples can be found from legged robots or industrial robots). Articulated robots can range from simple 6 Degree of Freedom structures to systems with 10 or more ...
Britain had become the world centre of autogyro development. A crash in February 1926, caused by blade root failure, led to an improvement in rotor hub design. A drag hinge was added in conjunction with the flapping hinge to allow each blade to move fore and aft and relieve in-plane stresses, generated as a byproduct of the flapping motion.
For purposes of air conditioning, the Han dynasty craftsman and engineer Ding Huan (fl. 180 CE) invented a manually operated rotary fan with seven wheels that measured 3 m (10 ft) in diameter; in the 8th century, during the Tang dynasty (618–907), the Chinese applied hydraulic power to rotate the fan wheels for air conditioning, while the ...

Milling is the process of machining using rotary cutters to remove material [1] by advancing a cutter into a workpiece. This may be done by varying directions [ 2 ] on one or several axes, cutter head speed, and pressure. [ 3 ]
The Peaucellier linkage generates a true straight-line output from a rotary input. The Sarrus linkage is a spatial linkage that generates straight-line movement from a rotary input. The Klann linkage and the Jansen linkage are recent inventions that provide interesting walking movements. They are respectively a six-bar and an eight-bar linkage.
