Sensors is a broad subcategory of hardware components responsible for collecting data from a robot's environment, mechanisms, and electronic systems. It encompasses distance, position, pressure, temperature, voltage, current, contact, and numerous other sensor types. This subcategory applies when a component is sensory in nature but does not belong to a more specific group such as LiDAR or Vision Components.

LiDAR is a distance sensor that uses laser beams to measure space and generate data about the surrounding environment. In robotics, it is used for navigation, SLAM, mapping, obstacle avoidance, and environmental perception. Depending on the model, it can provide 2D, 3D, or more advanced spatial representations. LiDAR is one of the primary sensors in mobile, autonomous, and humanoid robots.
