In robotics, a manipulator is a device used to manipulate materials without direct physical contact by the operator. The applications were originally for dealing with radioactive or biohazardous materials, using robotic arms , or they were used in inaccessible places.
A full parallel 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 ...
The Fuller calculator, sometimes called Fuller's cylindrical slide rule, is a cylindrical slide rule with a helical main scale taking 50 turns around the cylinder. This creates an instrument of considerable precision – it is equivalent to a traditional slide rule 25.40 metres (1,000 inches) long.
An example of a simple open chain is a serial robot manipulator. These robotic systems are constructed from a series of links connected by six one degree-of-freedom revolute or prismatic joints, so the system has six degrees of freedom. An example of a simple closed chain is the RSSR spatial four-bar linkage.
Such an integrated robotic system is called a "welding robot" even though its discrete manipulator unit could be adapted to a variety of tasks. Some robots are specifically designed for heavy load manipulation, and are labeled as "heavy-duty robots". [4] Current and potential applications include: Manufacturing. Robots have been increasingly ...
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.

Mobile Manipulator systems; mobile platform, robot manipulator, vision and tooling. A mobile robotic system combines the mobility offered by a mobile platform and dexterity offered by the manipulator. The mobile platform offers an extended workspace to the manipulator and more degrees of freedom to operate in. However, the operation of such a ...
Officially known as the Space Station Remote Manipulator System (SSRMS). Launched on STS-100 in April 2001, this second generation arm is a larger, more advanced version of the Space Shuttle's original Canadarm. Canadarm2 is 17.6 m (58 ft) when fully extended and has seven motorized joints (an 'elbow' hinge in the middle, and three rotary ...
