PDM28E Small Intelligent Robot Lawn Mower Electric Robot Lawn Mower Satellite Navigation Automatic Robot Lawnmowers Lawn Mover

GNSS satellites can locate terminals on the earth by relying on a three dimensional coordinate system. Satellite positioning has errors. Errors come from both inside and outside the system. For example, errors are caused when
satellite signals penetrate the ionosphere and troposphere, errors caused by the Doppler effect caused by high-speed satellite movement, multipath effect errors, channel errors, satellite clock errors, ephemeris errors, internal noise
errors, and so on. Some of these errors can be completely eliminated, while others cannot be eliminated or can only be partially eliminated, which affects the accuracy and reliability of the system. In order to better eliminate errors
and improve positioning accuracy, industry experts have developed a more powerful positioning technology, which is RTK, which reduces the error unit from meters to centimeters.

With advanced algorithms, the PDM28E can autonomously plan the optimal mowing route. Its systematic mowing pattern covers every corner of the lawn, ensuring high coverage and minimal missed areas. The PDM28E has a lower repetitive mowing rate and higher efficiency than traditional mowers. In addition, it also has an edge trimming function to ensure that the lawn is perfectly trimmed after each task.

With advanced algorithms, the PDM28E can autonomously plan the optimal mowing height. If the grass is too high, the electric cutter disc automatically adjusts the mowing height.

The full-frequency RTK-GPS module enhances positioning accuracy and stability in large lawn environments. Coupled with the intelligent navigation algorithm and powerful hardware performance, the PDM28E is able to handle large lawn areas more efficiently, and mowing tasks can be easily completed in as little as 24 hours for an area of up to 4,000 square meters.

Multi-Area Mowing Tasks

If you have multiple separate lawn areas, don’t worry, with the Kowoll app, you can easily create multiple mowing areas and add connecting paths and keep-out zones. The PDM28E will automatically perform multi-zone mowing tasks according to your settings.
