The simplest definition of a robot is any matter that has at least one degree of freedom and the robots which take the shape of a human are called humanoid. Robotics is the study of robots, making robots playing with them. Robots make our tasks easy, they can do repetitive tasks without getting bored.
They don’t need rest, they never get sick. At the best part they never complain moving on to the
fundamental blocks of a robot mechanical system, power supply systems, sensors, signal processing system and the control system.
Mechanical system comprises the chassis wheels and their placement. This system decides the locomotion of the robot. By this we can move our robot in any direction. The devices which convert electrical energy to mechanical energy and such devices are called actuators.
The most popular actuator is the DC motor. For a robot to work properly we need power supply which acts as fuel to the robot. Unless we feed the robot, it can’t work .We supply DC power which is given by a battery.
For the robot to be independent, we need a totally independent or autonomous system. Most of you will agree that it needs intelligence. This intelligence is imparted by us humans.
The robot will work with that yet it will be completely confined from the rest of the world.. For it to be interactive, implant sensors. A sensor is a device which is capable of sensing physical parameters like temperature, pressure, heat, magnetic fields, radio waves, IR waves etc.
Ascend to process the data from the sensors and allow electrical and digital signals to be processed so that the robot analyzes the situation and makes its move. For this, we introduce
electronic components to process the signal.
Every system that is present inside a robot and function can be represented in the form of a control system. Based on control robots are classified as manual semi autonomous and autonomous. Manuals are wired and wireless.
Autonomous are pre-programmed and self learning pre-programmed the example can be given as a line follower which one’s given a task to move on a black line. It keeps following a black line: self-learning is the obstacle detection robot.
Which move on their path when they detect an obstacle they move backwards and turn the position again.
Everything has advantages and disadvantages. One advantage of robots is they are faster than humans. They are automatic and we can use them where we can go like you know we can explore space we can explore minds.
We can explore volcanoes and see it’s so dangerous, but we can do that with the help of robots. The disadvantages of robots are that people can lose jobs in factories. We need more supply and need maintenance of the robots which becomes very costly.
Entrepreneurs hoping to introduce robots in their production lines/tasks face huge forthright expenses. All things considered, robots aren’t modest particularly when they’re innovative, first in class and required for a particular undertaking.
They can squeeze an association. Because of the power and labor needed to maintain robots in working control, the running costs included are high too. You need to trust that the expanded yield legitimizes the underlying speculation.
