Introduction To Robots And Robotics – Understanding The Basics! 

A robot is a programmable machine capable of performing tasks autonomously or semi-autonomously. Robotics, on the other hand, refers to the study and development of robots and automation. Robots come in various levels of autonomy, from human-controlled machines to fully autonomous systems that operate without external input.

At its core, a robot is a programmable machine capable of executing a task. The term robotics refers to the field that concentrates on creating and improving these robots and their automation. Robots exhibit various degrees of autonomy, ranging from human-controlled robots to fully autonomous machines operating without external intervention.

Robotics has evolved significantly since its inception. In 2005, 90% of all robots were predominantly employed in automotive factories, performing tasks like welding or fastening car parts. 

Today, the scope of robotics has broadened to include robots that explore extreme environments, assist law enforcement, simplify surgical procedures, and conduct rescue missions.

 

The Fundamental Features of Robots

Despite the diversity in their designs and functions, robots typically share a few common characteristics:

  • Mechanical Structure: 

    • Robots have a mechanical structure that enables them to perform tasks in their designated environments. For instance, the Mars 2020 Rover’s motorized wheels, made of titanium tubing, allow it to traverse the harsh terrain of Mars.
  • Electrical Components: 

    • Robots require electrical parts to control and power the machinery. Typically, an electric current, like a battery, powers most robots.
  • Computer Programming:

    •  A programmed set of instructions is crucial for a robot to perform its tasks. Without this programming, a robot would be just another piece of machinery.

 

Unveiling the Etymology and Types of Robots

The term ‘robot’ is derived from the Czech word ‘robota,’ meaning ‘forced labor.’ It first seems in the 1920 play R.U.R., referring to mass-produced workers incapable of creative thinking.

Robots come in various shapes, sizes, and designs, each tailored to perform specific tasks efficiently. 

They are categorized into five types:

1. Pre-Programmed Robots: 

    • These robots operate in a controlled environment, performing simple, repetitive tasks. An example would be a mechanical arm on an automotive assembly line.

2. Humanoid Robots:

    •  Humanoid robots resemble humans in appearance and behavior, performing activities like running, jumping, and carrying objects. Sophia by Hanson Robotics and Atlas by Boston Dynamics are examples of humanoid robots.

3. Autonomous Robots:

    •  Autonomous robots operate independently without human supervision. They use sensors to perceive their environment and make decisions accordingly. The Roomba vacuum cleaner is a classic example of an autonomous robot.

Main Components of a Robot:

1. Control System:

  • Think of it as the robot’s brain. The control system houses the CPU, which acts as the central processing unit, receiving information from sensors, interpreting it, and sending commands to the actuators.
  • It’s the decision-maker, determining how the robot reacts to its environment and executes its tasks. It can be pre-programmed with specific instructions or use AI algorithms for more dynamic behavior.
  • Imagine a robot vacuum cleaner. Its control system analyzes sensor data like floor type and obstacle location, then directs the actuators to navigate and clean efficiently.

2. Sensors:

  • These are the robot’s eyes and ears, providing vital information about its surroundings. Different sensors detect various things:
    • Vision sensors: Cameras capture visual data, allowing robots to “see” their environment.
    • LiDAR sensors: Emit laser pulses to measure distances and obstacles.
    • Touch sensors: Detect pressure or contact, crucial for object manipulation and collision avoidance.
    • Temperature sensors: Monitor environmental temperature, important for tasks like cooking or firefighting.
  • The control system uses sensor data to make informed decisions and adjust its actions accordingly.

3. Actuators:

  • These are the robot’s muscles, responsible for movement. They convert electrical energy from the power supply into mechanical motion. Different types of actuators exist:
    • Motors: Electric motors power robot limbs, wheels, and other moving parts.
    • Servos: These controlled motors offer precise positioning and angle control.
    • Hydraulics/Pneumatics: Fluid pressure drives actuators for tasks requiring high force or speed.
  • Actuators work in conjunction with the control system, translating its commands into physical actions.

4. Power Supply:

  • This is the robot’s energy source, providing the juice to keep everything running. Options include:
    • Batteries: Common for portable robots, offering flexibility but requiring charging.
    • Electrical Grid: Industrial robots often plug directly into the grid for constant power.
    • Solar Panels: Eco-friendly option for robots operating in sunlight, like lawnmowers or drones.
  • The power supply needs to be sufficient for the robot’s tasks and operating time.

5. End Effectors:

  • These are the tools at the end of the robot’s arm or other manipulators. They’re essentially the robot’s hands and allow it to interact with its surroundings and perform specific tasks. Examples include:
    • Grippers: Used for grasping and manipulating objects of various shapes and sizes.
    • Welders: Specialized tools for high-temperature welding tasks.
    • Surgical instruments: Delicate tools for minimally invasive procedures.
  • End effectors are designed specifically for the robot’s intended purpose and are crucial for its functionality.

These five components work together in perfect harmony, forming the core of any robot. They enable robots to sense their environment, make decisions, move around, and interact with the world in ways that were once unimaginable. As technology continues to advance, these components will become even more sophisticated and powerful, paving the way for even more amazing robots in the future.
