dToF measures light travel time directly, while iToF infers distance from phase shift. dToF often suits longer unambiguous range; iToF often suits dense close- to medium-range depth. The better choice depends on sunlight…

iToF estimates depth by comparing the phase of emitted and reflected modulated infrared light. It can create dense depth maps at useful frame rates, but accuracy is shaped by multipath, ambient light, reflectivity, motio…

A multi-zone robot mower should support the number of working areas your yard needs, navigate the passages between them, store or edit maps clearly, and leave enough coverage margin for real mowing conditions. Disconnect…

ROS vSLAM combines camera-based motion estimation with simultaneous mapping, then exposes the result through ROS topics, transforms, and nodes. Reliable performance depends on camera choice, IMU fusion, calibration, sync…

GNSS is the satellite-positioning framework, GLONASS is one GNSS constellation, and RTK is a precision correction technique that uses carrier-phase observations plus reference data. Under good satellite visibility and co…

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…
