The World of Robotics: Understanding Its Capabilities and Limitations

The world is now how busy even we are not getting the time to do some tasks. and every day in every country they are doing there own research and designing some device/machine which helps humans to do their task so that we can get more time to think something different and can change the world as we think. So that instead of wasting time let’s go think about the machine.

Here I have planned to design something so that we can play with the micro-controllers as how to design a machine like a human who can do the human work. If you are thinking about what to do and how to do it, then let’s go-to design the machine.

What is a MACHINE?

The Machine is a device made by a human using different substances or parts to perform the human task commanded by the human to help the human.

Different Types of Machine

Basically, there are two types of the machine as according to their functionality compared to human such as:

Static Machine.
Dynamic Machine.

What is Static Machine?

The Machine which can’t move from one place to another place and needs human help to move to do the human task known as a static machine.

A static machine is a machine or device that does not rely on any external source of energy or motion to perform its function. A static machine is designed to use the forces acting upon it to generate the desired movement or output, without the need for an external power source.

What is a dynamic machine?

The machine can move like a human and do the human job known as a dynamic machine. Whenever we started to think about the dynamic machine and who can more smart and intelligent and can also think as a human then the new revolution came to the world with the advanced engineering technology as robots.

What is a Robot?

The robot is an electro-mechanical mobile machine that performs the operation according to the command or instruction given by the machine.

ypically include a combination of hardware components, such as actuators, sensors, and control systems, and software algorithms that enable them to perform their tasks.

Robots can be used in a variety of applications, including manufacturing, healthcare, agriculture, and domestic settings. They can perform tasks that are repetitive, dangerous, or difficult for humans to perform, such as welding, painting, and assembly.

What is Robotics?

The robotics is the technology that is used to design the most advanced dynamic machine to do human work efficiently.

Why we need a Robot?

In one sentence we can say to save human efforts. I have wondered what it would be like if there were no machines in the world to help us. Then let’s go discuss all the reasons why we need Robots?

To perform a task accurately and sufficiently.
To perform a task safely.
To avoid mistakes.
To perform the task without getting tired.
To achieve high throughput.

Actually, if we are discussing why we need robots, then there is no end to complete the discussion so let’s go discuss the history of Robotics.

History of Robotics:

The robotics is intertwined with the histories of technology, science, and the basic principle of progress. The technology used in computing, electricity, even pneumatics and hydraulics can all be considered a part of the history of robotics. The timeline presented is therefore far from complete. The Robotics currently represents one of mankind’s greatest accomplishments and is the single greatest attempt of mankind to produce an artificial, sentient being. It is only in recent years that manufacturers are making robotics increasingly available and attainable to the general public.

I am not going to discuss more history or any non-technical concepts here. So let’s go learn how to design a robot. The first thing we have to think when a baby getting birth he/she doesn’t know anything. parents are gradually teaching about all the parts of the body and then elaborating on what can he/she do with these parts means functions. Like this, we have to think about how to design a Robot who can do our job and also gradually can also think like us which is the latest technology as Artificial technology, Sixth sense technology, and Machine learning.

So to do all these we have to take a microprocessor or microcontroller where we can write some program and we can interface the sensors and actuators as human having legs, hands, eyes, ears, etc. If you want to know about the sensors and actuators then you can learn from my other blogs or can search in the search option.

To do this let’s go take any of the microcontrollers where all the features are available to do these. You can read different types of micro-controllers and there features in my processor menu. Among them, I am taking an AVR family microcontroller as a reference where we are going to design the robotics machines for startup learning. Here I am taking the example of an 8-bit AVR microcontroller as ATMEGA-8.

Basically to design a robot we need the different sensors as input and actuators as output. so for this here we are going to use the IR sensors and D.C. Stepper motors for the movement of the robot-like human.

Different Types of Robots

There are several types of robots, which can be classified based on their design, functionality, and application. Some of the most common types of robots include:

Industrial robots: These robots are used in manufacturing and industrial applications to perform tasks such as assembly, welding, and material handling. They are typically designed to perform specific, repetitive tasks, and are often highly specialized.
Service robots: These robots are designed to interact with humans and perform tasks such as cleaning, security, and delivery. They often have advanced sensors and navigation systems to allow them to operate in complex environments.
Humanoid robots: These robots are designed to resemble human form and movements, and are used for research and entertainment purposes. They often have advanced sensors and control systems that allow them to mimic human movements and interact with their environment.
Military robots: These robots are designed for use in military and defense applications, and are used for tasks such as surveillance, reconnaissance, and explosive ordnance disposal.
Medical robots: These robots are used in healthcare applications, such as surgery, rehabilitation, and diagnostics. They are designed to enhance the precision and accuracy of medical procedures and to improve patient outcomes.
Agricultural robots: These robots are used in agriculture to perform tasks such as planting, harvesting, and monitoring crops. They are designed to improve efficiency, reduce the cost of labor, and improve the quality of crops.
Domestic robots: These robots are designed for use in homes, and are used to perform tasks such as cleaning, cooking, and entertainment.

Working Principle of Robots

Robots work by using a combination of hardware components, such as actuators, sensors, and control systems, and software algorithms to perform their tasks.

Actuators: These are the components that produce movement in a robot. They can include motors, hydraulic cylinders, and pneumatic actuators, among others. Actuators are used to control the movement of the robot’s arms, legs, or other appendages.
Sensors: These are the components that allow a robot to perceive its environment. Sensors can include cameras, microphones, touch sensors, and proximity sensors, among others. The data collected by these sensors is used by the robot’s control system to make decisions about how to perform its tasks.
Control system: This is the brain of the robot, which consists of a microcontroller or computer and associated software. The control system uses the data from the sensors to make decisions about how to act, and then sends commands to the actuators to cause the robot to move.
Software: This is the set of algorithms that control the robot’s behavior. The software can include task-specific algorithms, navigation algorithms, and machine learning algorithms, among others. The software enables the robot to perform complex tasks, such as recognizing objects, navigating through its environment, and making decisions based on its experiences.

When a robot is activated, it uses its sensors to perceive its environment and its control system to process that information. The control system then sends commands to the actuators to cause the robot to move and perform its tasks. This process is repeated continuously, allowing the robot to carry out complex tasks automatically.

Advantages of Robots

Robots have several advantages, which include:

Increased efficiency and productivity: Robots can perform tasks faster and more accurately than humans, which can lead to increased efficiency and productivity.
Improved quality: Robots can perform tasks with a high degree of precision and repeatability, which can lead to improved product quality.
Reduced labor costs: Robots can perform tasks that are dangerous, difficult, or repetitive, which can reduce the need for human labor and lower labor costs.

Disadvantages of Robots

Robots also have several disadvantages, as below points:

High initial cost: Robots can be expensive to purchase, install, and maintain, which can be a barrier to entry for some companies.
Lack of flexibility: Robots are designed to perform specific tasks, which can limit their flexibility. They may not be able to adapt to changing conditions or perform tasks that are not part of their programming.
Job loss: The use of robots can lead to job loss, as they can perform tasks that were previously performed by humans. This can have a negative impact on the local economy and lead to unemployment.
Technical difficulties: Robots can be complex systems that are prone to malfunctions and technical difficulties. This can lead to downtime and decreased efficiency.
Lack of creativity: Robots do not have the ability to think creatively or solve complex problems in the same way that humans can. This limits their potential in certain industries.
Dependence on electricity: Robots rely on a constant source of electricity to operate, which can be a problem in the event of power outages or other disruptions.
Ethical concerns: The increasing use of robots raises ethical concerns, such as privacy and safety. There is also a risk that robots could be used for malicious purposes, such as espionage or cyberattacks.
Limited sensory capabilities: Robots have limited sensory capabilities compared to humans, which can limit their ability to perceive and respond to their environment.
