What sensors are commonly used in robot navigation?
Common sensors include LIDAR, ultrasonic sensors, cameras, and IMUs (Inertial Measurement Units).
How does LIDAR work in navigation?
LIDAR uses laser beams to measure distances by calculating the time it takes for the light to return after hitting an object.
Are there any advantages of using cameras over LIDAR?
Yes, cameras can provide rich visual information and are often cheaper, but they may struggle in low-light conditions.
What role do ultrasonic sensors play?
Ultrasonic sensors help in detecting nearby objects and measuring distances, especially in close-range navigation.
Can robots navigate without GPS?
Yes, robots can use other sensors like LIDAR, cameras, and IMUs for navigation in environments where GPS is unavailable.
