M18E robotic lawnmower is equipped with the self-developed "single point positioning GNSS module + inertial navigation" program; Using the spatio-temporal coherence of GNSS positioning in small scale, a specific path planning algorithm was used to realize the operation of the lawn mower along the parallel route, so as to realize the doubling of the operation efficiency of 100/h; Equipped with sensors such as collision to achieve intelligent perception of the operating environment, with a certain degree of self-learning and self-adaptation of the environment.
