Robotics is an area of engineering and science that encompasses electronics, mechanical engineering, and computer science, among other disciplines. This branch is concerned with the design, building, and use of robots, as well as sensory feedback and data processing. In the coming years, these are some of the technologies that will replace humans and human activities. These robots are designed to be utilised for a variety of tasks, however they are currently being used in sensitive environments such as bomb detection and deactivation. Robots can take on any shape, although many of them have a human-like look. The robots that have taken on a human-like appearance are expected to move, speak, and think like humans.
Robotics is the engineering discipline that deals with the conception, design, operation, and manufacture of robots. Issac Asimov, a science fiction novelist, claimed to be the first to name robotics in a short tale written in the 1940s. Issac proposed three principles for guiding these types of robotic robots in that scenario. Issac's three rules of Robotics were later named after these three ideas. The following are the three laws:

Humans will never be harmed by robots.

With the exception of breaking law one, robots will follow human commands.

Without breaking any other restrictions, robots will defend themselves.

Characteristics
The following are some of the properties of robots:
Robots have a physical body that they can move around in. They are maintained in place by their body's structure and moved by their mechanical components. Robots will be nothing more than a software programme if they don't have an appearance.
On-board control unit is another name for the brain in robots. This robot receives data and then sends commands as an output. Otherwise, the robot will just be a remote-controlled machine without this control device.
Sensors: These sensors are used in robots to collect data from the outside world and deliver it to the Brain. These sensors, in essence, have circuits in them that produce voltage.
Actuators are the robots that move and the pieces that move with the help of these robots. Motors, pumps, and compressors are examples of actuators. These actuators are told when and how to respond or move by the brain.
Robots can only work or respond to instructions that are given to them in the form of a programme. These programmes merely inform the brain when to do certain things, such as move or make sounds. These programmes only instruct the robot on how to make judgments based on sensor data.
The robot's behaviour is determined by the programme that was created for it. When the robot starts moving, it's easy to identify what kind of programme it's running.
