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.
Robert Williams (robot fatality)
His family sued the manufacturers of the robot, Litton Industries, alleging "that Litton was negligent in designing, manufacturing and supplying the storage system and in failing to warn [system operators] of foreseeable dangers in working within the storage area." In a 1983 jury decision, the court awarded his estate $10 million and concluded that there simply were not enough safety measures in place to prevent such an accident from happening. He would go down in history as the first recorded human death by robot. The award was raised to $15 million in January 1984. Litton settled with the estate of Williams for an undisclosed amount in exchange for Litton not admitting negligence.
