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.
I, Robot (short story)
The story is about a robot's confession. Some weeks earlier, its builder, Dr. Charles Link, built it in the basement. Link teaches his robot to walk, talk and behave civilly. Link's housekeeper sees the robot just enough to be horrified by it, but his dog is totally loyal to it. The robot is fully educated in a few weeks, Link then names it Adam Link, and it professes a desire to serve any human master who will have it. Soon afterwards, a heavy object falls on Dr. Link by accident and kills him. His housekeeper instantly assumes that the robot has murdered Dr. Link, and calls in armed men to hunt it down and destroy it. They do not succeed; in fact, they provoke the robot to retaliate, both by refusing to listen to it and by accidentally killing Dr. Link's dog. Back at the house, the robot finds a copy of "Frankenstein", which Dr. Link had carefully hidden from the robot, and finally somewhat understands the prejudice against it. In the end the robot decides that it simply is not worth killing several people just to get a hearing, writes its confession, and prepares to turn itself off.
