Robotic arms are simply manipulators which are made to behave just like the human arms. With the introduction of high end robots, the requirement for the robot parts is rising day by day. The new robotic arms are programmable and they are able to carry out functions just like a human arm. The links of the robotic arms are connected with the help of joints in such a way that it possesses the rotational movement and linear movement at the same time. Hence in this way, the robotic arms are able to carry out many functions.
Links, which are used to make the arms, can be compared to a kinematics chain. The chain is arranged in such a way that it looks like a human hand. One end of the chain, which is known as the business end is also called the end effecter. This part of the robotic arm is able to carry out a number of tasks based upon the programs. It can weld, it can grip any object and at the same time it can also spin any desired object. The working factor will be the requirement which means that it will do work according to your wishes. They are utilized in a number of places to perform a variety of tasks like welding in an assembly line.
There are numerous other applications of the robotic arms which are much advanced than the other tasks. They are used in space shuttles under the name of the SSRMS and they are a good example of the robotic arms. They have freedom in a number of directions and thus it could be said that they are superior to the human hands. They perform a number of important functions including the task of inspecting the space shuttle with the help of cameras and the sensors. These are attached to its business end i.e. end effecter.
We can clearly see that a number of advancements have taken place in the robotic arms, now it is up to us to use it. Robotic arms are usually automatic but in some cases they are manually controlled as well.
