Introduction
Robotic technology is at the forefront of the fourth industrial revolution, transforming industries, enhancing human capabilities, and reshaping the way we live and work. From automated factory lines to autonomous delivery drones and robotic surgeries, this field merges computer science, mechanical engineering, and artificial intelligence to create machines capable of carrying out tasks with high precision, efficiency, and autonomy.
A Brief History of Robotics
The concept of robotics dates back centuries, with early ideas traced to ancient civilizations. However, the real journey began in the 20th century:
- 1950s–1960s: The first programmable robot, Unimate, was introduced in General Motors factories for die-casting and welding jobs.
- 1970s–1980s: Robotic arms like the PUMA and SCARA were used in industrial applications.
- 1990s–2000s: Robots started entering medical and consumer domains. Sony’s AIBO and iRobot’s Roomba gained popularity.
- 2010s–present: With AI, sensors, and big data, robots evolved from static machines to intelligent agents capable of learning, adapting, and interacting with humans.
Core Components of Robotic Technology
1. Mechanical Structure
- Acts as the body of the robot.
- Includes joints, actuators, wheels, and limbs, depending on the robot’s design and use.
2. Sensors
- Provide data about the robot’s surroundings or internal state.
- Examples: LIDAR, cameras, pressure sensors, GPS, infrared, and ultrasonic sensors.
3. Actuators and Motors
- Enable movement by converting energy into mechanical motion.
- Common types include servo motors, stepper motors, and hydraulic actuators.
4. Control System
- The “brain” of the robot.
- Executes programmed instructions or decisions based on real-time sensor data.
5. Artificial Intelligence and Machine Learning
- Allow robots to learn from data, recognize patterns, and make decisions autonomously.
- Integral to self-driving cars, conversational robots, and smart drones.
