Movement Path Control Device and Method

Movement Path Control Device Using Distance Difference and Sum Calculation of Boundary Signal Generators

This technology is a movement path control device that receives signals from multiple signal generators located on a boundary line to calculate the distance between an object and each signal generator, and analyzes changes in distance differences and sums to determine the object's angle of incidence and whether it has crossed the boundary.

Existing systems have struggled to maintain stable work zones because it is difficult to determine and control in real-time when an autonomous object deviates from a designated boundary.

This technology proposes a method that determines if the angle of incidence relative to the boundary is perpendicular based on changes in the distance difference between two signal generators, and detects boundary deviation based on changes in the distance sum. It can be applied to robotic lawnmowers and outdoor autonomous work machines to accurately maintain work zones without the need for physical fences.

Key Features:

• A signal receiver that receives signals from multiple signal generators located on a boundary line
• A distance calculator that calculates the distance to an object using signals received from the first and second signal generators
• A first processing unit that calculates the change in the distance difference between the two signal generators to determine the object's angle of incidence relative to the boundary
• A configuration that determines whether an object has deviated from the boundary using the change in the sum of distances between the two signal generators
