Robots that work in hazardous environments, such as chemical plants or oil rigs, can perform dangerous tasks like handling toxic materials, cutting, or welding. These robots are controlled remotely, allowing humans to prevent themselves from any harm while completing these dangerous tasks.
How do robots improve safety in hazardous work environments, such as chemical plants or nuclear reactors?

A factory uses industrial robots for high-precision tasks. These robots are programmed to perform tasks like welding and cutting, ensuring consistent quality. Which feature of these robots allows them to perform these tasks with high accuracy and minimal error?

1. They are equipped with infrared sensors.
2. They operate in extreme environments.
3. They have a high degree of precision.
4. They require continuous human guidance.

Consider a robot used in military applications to handle hazardous materials like explosives. Which feature is most essential for this robot to ensure human safety while performing such critical tasks?

1. Autonomous decision-making abilities
2. High durability and strength for rough terrains
3. Sensors to detect temperature changes
4. Remote control for human operators to stay at a safe distance

Sensors are vital components of robots, enabling them to detect environmental changes. These devices gather data related to temperature, pressure, light, sound, and distance, which are used by robots to detect obstacles, navigate, and make decisions. Common types of sensors include temperature sensors, ultrasonic sensors, and proximity sensors. These sensors act as input devices, providing essential information that helps robots function autonomously in different settings.
