Robotic Arm
A robotic arm is a type of mechanical arm, usually programmable, with similar functions to a human arm; the arm may be the sum total of the mechanism or may be part of a more complex robot. The links of such a manipulator are connected by joints allowing either rotational motion (such as in an articulated robot) or translational (linear) displacement. The links of the manipulator can be considered to form a kinematic chain. The terminus of the kinematic chain of the manipulator is called the end effector and it is analogous to the human hand. However, the term "robotic hand" as a synonym of the robotic arm is often proscribed. Types * Cartesian robot / Gantry robot: Used for pick and place work, application of sealant, assembly operations, handling machine tools and arc welding. It is a robot whose arm has three prismatic joints, whose axes are coincident with a Cartesian coordinator. * Collaborative robot / Cobot: Cobot applications contrast with traditional industri ...

STS-3 Canadarm Captures PDP
STS-3 was NASA's third Space Shuttle mission, and was the third mission for the Space Shuttle ''Columbia''. It launched on March 22, 1982, and landed eight days later on March 30, 1982. The mission, crewed by Jack R. Lousma and C. Gordon Fullerton, involved extensive orbital endurance testing of ''Columbia'' itself, as well as numerous scientific experiments. STS-3 was the first shuttle launch with an unpainted external tank, and the only mission to land at the White Sands Space Harbor near Alamogordo, New Mexico. The orbiter was forced to land at White Sands due to flooding at its originally planned landing site, Edwards Air Force Base. Crew Commander Jack R. Lousma previously flew as pilot of the second Skylab crew ( Skylab 3), staying aboard the space station for 59 days from July to September 1973. Lousma had previously been selected in 1978 as Pilot for STS-2, which was then scheduled as a Skylab reboost mission. When delays in the Shuttle's development prevented ' ...
