Mechanical arm
Other robotic arms were invented in 1961 by Unimate, evolving to the PUMA arm. In 1963, the Rancho arm was designed, along with many others in the future. Even though Joseph Engelberger marketed Unimate, George Devol invented the robotic arm. It focused on using Unimate for tasks that are harmful to humans. In 1959, a 2700 pound Unimate prototype was installed at the General Motors die-casting plant in Trenton, New Jersey. The Unimate 1900 series became the very first produced robotic arm for die-casting. During a very short period of time, it had produced at least 450 robotic arms were being used. It still remains one of the most significant contributions in the last one hundred years. As years went by, technology seemed to evolve, helping to build better robotic arms. Not only companies invented different robotic arms, but so did colleges. In 1969, Victor Scheinman from Stanford University invented the Stanford arm, where it had electronically powered arms that could move through six axes. Marvin Minsky, from MIT, built a robotic arm for the office of Naval Research, possibly for underwater explorations. This arm had twelve single degree freedom joints in this electric- hydraulic- high dexterity arm. Robots were initially created to perform a series of tasks that humans found boring, harmful, and tedious.
History of robots
The P3 humanoid robot was revealed by Honda in 1998 as a part of the company's continuing humanoid project. In 1999, Sony introduced the AIBO, a robotic dog capable of interacting with humans; the first models released in Japan sold out in 20 minutes. Honda revealed the most advanced result of their humanoid project in 2000, named ASIMO. ASIMO can run, walk, communicate with humans, recognise faces, environment, voices and posture, and interact with its environment. Sony also revealed its Sony Dream Robots, small humanoid robots in development for entertainment. In October 2000, the United Nations estimated that there were 742,500 industrial robots in the world, with more than half of them being used in Japan.
