Two time-of-flight sensors can both report depth yet behave very differently at long range, in bright light, or around reflective objects. The reason is that dToF times returning light directly, while iToF interprets pha…

A depth camera may look accurate indoors and then become noisy beside a bright window or on a glossy surface. That change is often tied to how the sensor interprets returning infrared light rather than a simple “range” l…

A front lawn, side strip, backyard, and shaded garden may belong to one property but behave like four different mowing jobs. Passages can be narrow, some areas may be disconnected, and each zone may need its own schedule…

A robot can publish clean camera images in ROS and still drift, jump, or lose its map after a fast turn. In many projects, the weak point is not the core algorithm but timestamps, calibration, coordinate frames, motion b…

An RTK receiver can show a fixed centimeter-level solution in an open field and then lose that precision beside trees or a building. Understanding why requires separating three ideas that are often mixed together: GNSS i…

When a robotic mower follows a lawn edge accurately on one pass but drifts toward a flower bed on the next, the problem is rarely the RTK specification alone. Trees, walls, antenna placement, and an unstable correction l…
