ROBOT ARMS

 Hello ladies and gents this is the Viking telling you that today we are talking about

Robotic Arms

Researchers have classified the robotic arm by showing its industrial application, medical application, and technology, e.t.c. It has been first introduced in the late 1930s by William Pollard and Harold A. Roseland, where they developed a sprayer that had about five degrees of freedom and an electric control system. Pollard's was called “first position controlling apparatus.” William Pollard never designed or built his arm, but it was a base for other inventors in the future.

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.

Prosthetics

Before the Modern Era

The history of prosthetic limbs came to be by such great inventors. The world's first and earliest functioning body parts are two toes from Ancient Egypt. Because of their unique functionality, these toes are an example of a true prosthetic device. These toes carry at least forty percent of the body's weight. Most prosthetic limbs would be produced after there is intensive studying of a human being's form by using modern equipment.

Prosthetic limbs were used during the war too, including during the late 1480s. A German knight, who served with the Holy Roman Emperor Charles V, was injured during the war. Even though prosthetic limbs were expensive, this particular limb was manufactured by an armor specialist. Soldiers were allowed to continue their career because of prosthetics. The fingers could grasp a shield, hold reins to horses, and even a quill when drafting an important document.

Modern Era

As time passed, limb design started to focus on people's specialties as well. For example, a pianist would need a different type of mechanical arm than others. Their limbs would be widespread and their middle and ring fingers would be smaller than normal. In addition, an arm design of padded tips on the thumb and little finger would allow a pianist to span a series of notes while playing their instrument.

Technology for the prosthetic limbs kept evolving after World War I. After the war, laborers would return to work, using either legs or the arms because of its ability to grip objects. This is one of the designs that remains unchanged over the past century. People with such prosthetics would do everyday things like driving a car, eating food, and much more
