Robots can be defined as programmable machines capable of carrying out a series of actions autonomously or semi-autonomously. There are several types of robots, including:

• Industrial robots
• Service robots
• Humanoid robots
• Autonomous vehicles
• Medical robots

The historical advancements in robotics began with simple mechanical devices, but significant milestones such as the introduction of programmable logic controllers (PLCs), artificial intelligence (AI), and machine learning have propelled the field forward. Sensors play a crucial role in these advancements; they enable robots to gather data about their surroundings, which is essential for performing tasks like navigation, object recognition, and interaction with humans and other machines.

III. The Role of Sensors in Robotics

Sensors are devices that detect and measure physical properties in the environment, converting these inputs into signals that can be processed by a robot’s control system. They function by utilizing various principles of physics, such as light, sound, and pressure. The types of sensors commonly used in robotics include:

• Proximity sensors: Used to detect the presence of nearby objects without physical contact.
• Vision sensors: Cameras and imaging technologies that allow robots to “see” and interpret their surroundings.
