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 ...
The manufacturing environment is defined by its ability to manufacture and/or assemble goods by machines, integrated assembly lines, and robotic arms. Automated environments are also defined by their coordination with (and usually their systematic integration with) the required automatic equipment to form a complete system. [5]
Victor Scheinman's MIT Arm, built for MIT's Artificial Intelligence Lab ca. 1972, the first arm designed with a 321 kinematic structure 321 kinematic structure is a design method for robotic arms ( serial manipulators ), invented by Donald L. Pieper and used in most commercially produced robotic arms.
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 ...
The Unimate 1900 series became the very first produced robotic arm for die-casting. During a very short period of time, had been produced at least 450 robotic arms which were being used. It still remains one of the most significant contributions in the last one hundred years. As years went by, technology evolved, helping to build better robotic ...
First, to fix the substrate and move the cold spray gun/nozzle using a robotic arm; the second one is to move the substrate with a robotic arm, and keep the spray-gun nozzle fixed. There is also a possibility to combine these two approaches either using two robotic arms [1] or other manipulators. [2]
Soon, robotic arms were exploding within the large-scale manufacturing industry and several new companies came into existence including Kuka in 1973, Nachi in 1969, Fanuc in 1974, Yaskawa in 1977, ASEA in 1977, and several others. By 1980, it is estimated a new major robotics company entered the market every month. [4]
The acronym stands for selective compliance assembly robot arm [1] or selective compliance articulated robot arm. [ 2 ] By virtue of the SCARA's parallel-axis joint layout, the arm is slightly compliant in the X-Y direction but rigid in the Z direction, hence the term selective compliance .
