What is a Robot?
When we think of a robot, we often imagine a futuristic machine with the ability to think, act, and perform tasks autonomously. Indeed, robots are extraordinary creations that have the power to accomplish complex actions without direct human involvement. They possess a remarkable combination of mechanical components, sensors and intelligent algorithms that enable them to interact with their environment and carry out specific functions.
The mechanical parts of a robot are just like our arms and legs, providing them with the ability to move and manipulate objects. These parts can vary widely depending on the robot's intended purpose. For instance, some robots have wheels that allow them to move across different surfaces, while others may have legs for moving across uneven terrains or even wings for aerial movement. These mechanical components are often accompanied by actuators, which are devices responsible for generating and controlling the robot's physical movements. Actuators can be motors, hydraulics, or pneumatics that convert electrical or hydraulic signals into precise mechanical actions.
In order to interact with their surroundings, robots rely on sensors that act as their senses. These sensors collect data from the environment, providing information about distances, shapes, colors, sounds, and more. Just as we use our eyes, ears, and other senses to perceive the world, robots are equipped with cameras, microphones, infrared sensors, touch sensors, and other devices that allow them to sense and interpret their surroundings. This sensory input is crucial for robots to make informed decisions and carry out their tasks effectively.
The decision-making process of a robot is governed by intelligent algorithms and control systems. These algorithms analyze the sensory data received from the environment and enable the robot to make decisions based on predefined rules or even learn from experience using artificial intelligence techniques. By processing the information gathered by its sensors, a robot can determine the most appropriate actions to take, whether it's picking up an object, navigating through an obstacle course, or performing a complex surgical procedure. The algorithms also govern the coordination of the robot's mechanical parts and actuators to execute precise and coordinated movements.
In simple words, a robot is a machine in which hardware and software work efficiently in sync so that it can perform tasks and actions without human assistance. And Botted is there to make you ready for building your own robots.

Mechanical components form the foundation of a robot's hardware. These components include motors, linkages, actuators, grippers, end effectors, wheels and other mechanical parts responsible for the robot's physical movements. To make a robot’s mechanical design, we may take help of software's such as creo, onshape, solidworks, etc.
The Electronics of a robot includes all its PCBs including the brain of the robot i.e microcontroller. It also comprises of the power supply , motor drivers, memory and storage devices. To design energy efficient circuit boards, we may take the help of software's such as easyEDA, eagle, CAD, etc.
Sensors play a crucial role in a robot's ability to gather information from its surroundings. They are the robot's eyes and ears, enabling it to perceive the world. Different types of sensors are used depending on the robot's purpose and environment. For example, proximity sensors detect the presence of objects in the robot's vicinity, while cameras capture visual information. Other sensors can measure distance, temperature, force, or sound, allowing the robot to gather relevant data about its surroundings.
Once the sensors collect information, they send it to the robot's "brain," which is a computer or microcontroller(Arduino, ESP, STM etc.). This brain serves as the central processing unit of the robot, responsible for interpreting the sensory data and making decisions based on pre-programmed instructions or artificial intelligence algorithms.
The computer programs or software running on the robot's brain determine how it should interpret the sensor data and respond to different situations. Programming is basically giving commands to your robot. Just like we communicate using languages, we can communicate with the robot with the help of programming languages like Python, C++ etc.
The most popular tools for programming robots are Arduino IDE, ROS. Programming binds the robot’s mechanical, electronics and sensors so that they work in sync.
The processing of sensor data involves various algorithms, such as image recognition, object tracking, or sound analysis. These algorithms enable the robot to understand its environment, identify objects or obstacles, and extract meaningful information from the raw sensor data.
Based on the processed information, the robot's brain generates commands that are sent to the actuators and motors, initiating the robot's physical movements and actions. For example, if a robot detects an obstacle in its path, its brain will generate instructions to adjust its trajectory or stop to avoid a collision.
Workflow of a Robot:
The workflow of a robot involves several key steps and processes that allow it to perform tasks and interact with its environment. Here's a simplified explanation of how a robot typically works:

3. Decision-making: Based on the processed information, the robot's control system makes decisions and generates appropriate commands. This control system can be pre-programmed instructions, a rule-based system, or an advanced artificial intelligence algorithm that enables the robot to make intelligent decisions.
4. Actuation: The commands generated by the control system are sent to the robot's actuators. Actuators are mechanical devices responsible for converting the generated commands into physical motion. Electric motors, hydraulic systems, or pneumatic systems are commonly used actuators in robots.
5. Movement and Manipulation: The actuators drive the mechanical parts of the robot, such as joints and linkages, to perform desired movements. By controlling the actuator's motion and power, the robot can navigate its environment, manipulate objects with grippers or end effectors, or perform specific tasks.
6. Feedback and Iteration: Throughout the robot's operation, sensors continue to provide feedback on the robot's actions and the state of its environment. This feedback allows the robot to adapt its behaviors', adjust its movements, or modify its decision-making process to accomplish tasks more effectively.
7. Repeat: The robot repeats this cycle of perceiving, processing, deciding, actuating, and receiving feedback in a continuous loop, allowing it to interact with its environment, perform assigned tasks, and make real-time adjustments as necessary.
It's important to note that the working of a robot can vary significantly depending on its design, purpose, and complexity.
