The advances of technology in the field of robotics every day offers us a wide variety of inventions. It also provides different types of machines. These inventions have a primary purpose: to aid mechanical work in factories.

Among the most prominent machines we can specify:

The Robotic Arm

Another name for the Robotic Arm is the Mechanical arm. Engineers can program these arms, and their main functions are like those of a human arm. These mechanical arms can be independent or can also be part of a more complex robot.

Their different parts connect to make their movements of rotation and translation. They have extended uses since they allow higher speed and range of motion than the human arm. They can also perform more delicate tasks. For example, they can adjust parts or screws in many different structures.

George Devol invented the robotic arm. He applied for a patent in 1954 for a mechanical arm that he could program to repeat precise tasks. General Motors was the first to put a few hundred of these arms in its factory. The concept soon spread, and companies like Ford and Chrysler became customers. Robotic hands are accurate and can repeat the same action over and over again. Thus, companies use them for functions that are repetitive and difficult. They are also useful for applications that are boring to humans.

The manufacturers of these machines use durable metal alloys to make them. Their design allows for anchorage to a surface. Thus, robotic arms can withstand weights that far exceed what the human arm can bear. They can lift hefty metal parts. Robotic arms have become necessary installations in factories today.

Robotic Hand Abilities

This machine simulates the shape of the human hand. It fulfills the same functions, only improved.

Engineers created robotic hands for a wide variety of functions. Because they have high precision, users can adjust, weld, or rotate them.

Several models exist, which vary depending on the industry and the tasks the robot has to perform. If the tasks are very demanding or need higher precision, this hand may change its shape.

A robotic arm has some segments joined by joints, controlled by a computer, which rotates its motors. Large robotic arms use hydraulic systems. Unlike other engines, these arms move in exact increments. This range gives the computer the ability to move the arm in a precise way. Thus, it is possible to repeat movements precisely several times. The robot uses several motion sensors to ensure that it moves only as necessary.


Robotic arms have both medical and industrial applications. Many industries, from material handling, to welding, to thermal spraying, also use it. Robotic arms are also useful for drilling and painting. These arms can service nuclear power stations. They can weld and repair pipelines on the ocean floor and service utility power lines. They can also clean up radioactive and other hazardous waste. Robotic arms are a boon to the auto manufacturing industry. Most industrial robots work in auto assembly lines, putting vehicles together.

Among some of its other functions we find:

1. Use in applications that improve the quality of open environments. Cities use them to clean public roads and for the maintenance of green areas. They are also useful for the detection of explosives and deactivation, among others.

2. Use in closed habitable environments. In this field of application, there is a large population sector. It includes children, the elderly, and people with cognitive and other disabilities. These people may need more or less permanent aid. The robotic device can perform tasks such as cleaning glasses. It can also feed the patients or brush their teeth.

The future holds much in store for the robotic arm. One day it may even control delicate operations in the recesses of the human brain.
