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.
Robot Patent
The Robot Patent is an English-language scholarly term for the imperial decrees (patents) in the 1700s abolishing compulsory labor (robot) of serfs, issued by Joseph II, Holy Roman Emperor, who had carried out a register of all land with a division between peasant and noble holdings.
Joseph II outlawed the buying of 'rustic' land by the nobility and at the same time giving the rusticalists security of tenure. His motive was to prevent the increase in 'dominical' land, which paid fewer taxes to the government. This led to the survival of the peasantry, with rustic land still having the robot. In 1789 it was abolished by Joseph II, however Leopold II restored it when his brother Joseph II died in 1790. The abolition of robot during the Revolutions of 1848 broke the last legal tie which held the peasants to the land, and was seen as a great victory by the peasants.
