LiDAR vs cameras & structured light
The sensor list on a product page can sound like a hierarchy — more sensors must mean a better robot. In practice, each sensing system solves a slightly different problem and the implementation matters at least as much as the label.
The useful versionChoose for the behaviour you need: reliable mapping, small-object avoidance, privacy, or a low body that fits under furniture.

What actually matters
LiDAR is usually excellent for fast, repeatable mapping and works without needing a brightly lit room. A top-mounted LiDAR turret can make a robot taller, though. Cameras and structured-light sensors can help recognise smaller objects such as cables, shoes and pet mess, but real-world avoidance varies a lot between models.
- LiDAR is particularly useful for fast room mapping and repeatable navigation, including in low light.
- Camera or structured-light systems can add object recognition, but they do not guarantee perfect cable, toy or pet-mess avoidance.
- A raised LiDAR turret can increase robot height; low-profile designs may use alternative sensing layouts.
