This motion was smoothed by an oil-filled dashpot, one for each of the three servos. [42] The entire ABS sat within the stabilised frame that was powered by the servos. The platform had fairly wide range of motion, between 20 and 25 degrees off horizontal. [43] This allowed it to track properly through a wide range of motions.
Range of motion (or ROM) is the linear or angular distance that a moving object may normally travel while properly attached to another. In biomechanics and strength training , ROM refers to the angular distance and direction a joint can move between the flexed position and the extended position. [ 1 ]
The masseter muscle itself is often divided into superficial, lateral, and medial components, allowing for a wide range of jaw motion, particularly the anteroposterior or propalinal movement (front-to-back chewing motion) characteristic of rodents.
A manipulator can move an object with up to 6 degrees of freedom (DoF), determined by 3 translation 3T and 3 rotation 3R coordinates for full 3T3R mobility. However, when a manipulation task requires less than 6 DoF, the use of lower mobility manipulators, with fewer than 6 DoF, may bring advantages in terms of simpler architecture, easier control, faster motion and lower cost.

A similar system was planned to be installed on the Blue Devil blimp, a spy blimp developed for the US Air Force. [17] However, the Blue Devil was cancelled in 2012. [14] In 2006, a similar wide-area surveillance system, Constant Hawk, was being tested by the US Army.
[4] [5] [6] A kinematics problem begins by describing the geometry of the system and declaring the initial conditions of any known values of position, velocity and/or acceleration of points within the system. Then, using arguments from geometry, the position, velocity and acceleration of any unknown parts of the system can be determined.
When passive range of motion is applied, the joint of an individual receiving exercise is completely relaxed. At the same time, the outside force moves the body part, such as a leg or arm, throughout the available range. Injury, surgery, or immobilization of a joint may affect the normal joint range of motion. [7] Active range of motion is the ...
The virtual displacements, δr k, are by definition infinitesimal changes in the configuration of the system consistent with the constraint forces acting on the system at an instant of time, [22] i.e. in such a way that the constraint forces maintain the constrained motion. They are not the same as the actual displacements in the system, which ...
