Basics of a robotic arm
If you see a human body, then one of the most distinctive parts that makes us able to be different than most other species is the arm. It is the part of the body that we use to do most of the work.
The human arm is a very complex mechanism of joints and muscles that work in tandem to give it the dexterity that we know it for. Take an example of our shoulder joint. If you pay attention, then you will notice that it has the ability to move up and down, right and left, and even rotate on its own axis, and all this while it just has one single joint, which we know as a ball joint.
When we talk about a robotic arm on a robot, we are undoubtedly talking about a complex arrangement of actuators with the body, otherwise known as a chassis, to get the desired motion in a three-dimensional space.
Now, let's understand some of the basic parts of any robotic arm. The first parts are the actuators. We can use motors to control the robotic arm; however, as we have studied earlier...
