Cheap 2D LiDAR can help indoor navigation if the robot also has encoders, IMU and sane expectations.
Cheap LiDAR is useful for scanning walls and obstacles, but it does not magically make a robot autonomous. The robot still needs odometry, motor control and a navigation stack.
Buy LiDAR after your rover drives repeatably. Otherwise you will debug mapping and bad mechanics at the same time.
Room scan and obstacle map
Motion estimate
Heading support
Mapping and navigation compute
Prevents USB and sensor resets
LiDAR, encoders and slow indoor rover.
Use LiDAR for stop zones without full SLAM.
Treat the generated output as a prototype plan, not a certified product. Body-adjacent, high-voltage, optical-energy and mobility builds need qualified review before real-world use.
Yes in simple indoor spaces, if odometry and compute are stable.
Very noisy sensors with poor software support.
For 2D geometry indoors, often. Cameras provide richer but harder data.
LiDAR vs ToF sensor for robot builds: compare cost, range, mapping use cases and beginner-friendly choices.
