Gliders from University of Miami. A glider or platform rocker is a type of rocking chair that moves as a swing seat, where the entire frame consists of a seat attached to the base by means of a double-rocker four-bar linkage. The non-parallel suspension arms of the linkage cause the chair to simulate a rocking-chair motion as it swings back and ...
"A glider is an updated version that’s designed to slide forward and backward rather than rock in an arc". See Four bar linkage, "parallelogram" linkage. Granted, not all gliders purely glide back & forth, some do "rock" and change the tilt angle. Likewise, some gliders have the four-arm mechanism mostly enclosed and are safer than a rocker.
Some mechanisms that produce reciprocating, or repeating, motion are designed to produce symmetrical motion. That is, the forward stroke of the machine moves at the same pace as the return stroke. These mechanisms, which are often referred to as in-line design, usually do work in both directions, as they exert the same force in both directions. [6]
Reaction control systems are capable of providing small amounts of thrust in any desired direction or combination of directions. An RCS is also capable of providing torque to allow control of rotation (roll, pitch, and yaw). [2] Reaction control systems often use combinations of large and small thrusters, to allow different levels of response.
This animation shows the working of a klann mechanism. This is a repeating animation of the legs in motion with the near legs of each set outlined in blue. A reasonable understanding of the functioning of the linkage can be gained by focusing on a specific point and following it through several cycles. Each of the pivot points is displayed in ...
A rocker bogie In motion - incorrectly shows chassis staying level; the chassis actually maintains the average of the two rockers Rocker bogie on Curiosity. The rocker-bogie system is the suspension arrangement developed in 1988 for use in NASA's Mars rover Sojourner, [1] [2] [3] and which has since become NASA's favored design for rovers. [4]
