For example, if the part was shifted 0.25 mm and rotated 10° when picked up, the pickup head will adjust the placement position to place the part in the correct location. Some machines have these optical systems on the robot arm and can carry out the optical calculations without losing time, thereby achieving a lower derating factor.

Commercial pick and place robots. The delta robot (a parallel arm robot) was invented in the early 1980s by a research team led by professor Reymond Clavel at the École Polytechnique Fédérale de Lausanne (EPFL, Switzerland). [5] After a visit to a chocolate maker, a team member wanted to develop a robot to place pralines in their packages. [6]
Serial robots usually have six joints, because it requires at least six degrees of freedom to place a manipulated object in an arbitrary position and orientation in the workspace of the robot. A popular application for serial robots in today's industry is the pick-and-place assembly robot, called a SCARA robot, which has four degrees of freedom.
The 1961 Unimate installed at a General Motors factory differed significantly from George Devol's 1954 patented design. The Unimate was a hydraulically actuated programmable manipulator arm with 5 degrees of freedom. This contrasted with the simpler three-prismatic-link pick-and-place arm described in Devol's "Programmed Article Transfer" (PAT ...
