In space, the Canadarm and its successor Canadarm2 are examples of multi degree of freedom robotic arms. These robotic arms have been used to perform a variety of tasks such as inspection of the Space Shuttle using a specially deployed boom with cameras and sensors attached at the end effector, and also satellite deployment and retrieval manoeuvres from the cargo bay of the Space Shuttle.
The PUMA (Programmable Universal Machine for Assembly, or Programmable Universal Manipulation Arm) is an industrial robotic arm developed by Victor Scheinman at pioneering robot company Unimation. Initially developed by Unimation for General Motors , the PUMA was based on earlier designs Scheinman invented while at Stanford University based on ...
It is an arm-like mechanism that consists of a series of segments, usually sliding or jointed called cross-slides, [2] which grasp and move objects with a number of degrees of freedom. In industrial ergonomics a manipulator is a lift-assist device used to help workers lift, maneuver and place articles in process that are too heavy, too hot, too ...
A six-axis articulated welding robot reaching into a fixture to weld. An articulated robot is a robot with rotary joints [citation needed] that has 6 or more Degrees of Freedom. This is one of the most commonly used robots in industry today (many examples can be found from legged robots or industrial robots). Articulated robots can range from ...
The position and orientation of a robot's end effector are derived from the joint positions by means of a geometric model of the robot arm. For serial robots, the mapping from joint positions to end-effector pose is easy, the inverse mapping is more difficult. Therefore, most industrial robots have special designs that reduce the complexity of ...
Canadarm or Canadarm1 (officially Shuttle Remote Manipulator System or SRMS, also SSRMS) is a series of robotic arms that were used on the Space Shuttle orbiters to deploy, manoeuvre, and capture payloads.
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.
Delta robot kinematics (green arms are fixed length, at 90° to their blue axis that they rotate about) Over-actuated planar delta robot. The delta robot is a parallel robot, i.e. it consists of multiple kinematic chains connecting the base with the end-effector. The robot can also be seen as a spatial generalisation of a four-bar linkage. [9]
