Robot arms are described by their degrees of freedom. This is a practical metric, in contrast to the abstract definition of degrees of freedom which measures the aggregate positioning capability of a system. [3] In 2007, Dean Kamen, inventor of the Segway, unveiled a prototype robotic arm [4] with 14 degrees of freedom for DARPA.
Full motion racing simulator with all 6 degrees of freedom. A full motion racing simulator, sometimes called a full motion sim rig, is a motion simulator that is purposed for racing, and must provide motion simulation in all six degrees of freedom, as defined by the aviation simulator industry many decades ago.
In 1958 a flight simulator for the Comet 4 aircraft used a three-degrees-of-freedom hydraulic system. Simulator motion platforms today use 6 jacks ("Hexapods") giving all six degrees-of-freedom, the three rotations pitch, roll and yaw, plus the three translational movements heave (up and down), sway (sideways) and surge (longitudinal).
A single rigid body has at most six degrees of freedom (6 DOF) 3T3R consisting of three translations 3T and three rotations 3R. See also Euler angles. For example, the motion of a ship at sea has the six degrees of freedom of a rigid body, and is described as: [2] Translation and rotation: Walking (or surging): Moving forward and backward;
Video games in which the player has a full six degrees of freedom (6DOF) over the vehicle (or other element) being controlled. Note that not all video games in Category:Space combat simulators exhibit 6DOF. For example, Freespace allows full 3DOF rotations and longitudinal control, yet it does not give vertical or horizontal strafing control ...
Requirements are for Level C with additions. The motion platform must have all six degrees of freedom, and the visual system must have an outside-world horizontal field of view of at least 150 degrees, with a collimated (distant focus) display. Realistic sounds in the cockpit are required, as well as a number of special motion and visual effects.
The motion platform must produce accelerations in all of the six degrees of freedom (6-DoF) that can be experienced by a body that is free to move in space, using a principle called acceleration onset cueing, generally using the Stewart platform design.
In other words, degrees of freedom are the minimum number of parameters required to completely define the position of an entity in space. A rigid body has six degrees of freedom in the case of general spatial motion, three of them translational degrees of freedom and three rotational degrees of freedom.
