Robots utilize sensors to navigate their environment by collecting data about their surroundings, which informs their movement and decision-making processes. These sensors can detect obstacles, measure distances, and identify changes in terrain or conditions. By processing this data, robots can create a detailed map of their environment, allowing them to make decisions such as path planning and avoiding hazards. This sensory feedback is essential for autonomous operation, enabling robots to perform tasks in various domains such as manufacturing, exploration, and healthcare.
