Distance-measuring drone with enhanced horizontal stability during surveying tool movement

Surveying drone that maintains stable hovering by adjusting its center of gravity with telescopic, rotating thrust arms

This technology features a surveying drone equipped with a built-in sensor module for stable hovering, a surveying position adjustment mechanism consisting of a horizontal guide and a support pole, and a laser surveying tool that moves along the support pole to measure the target distance from a reference point. The drone body is equipped with rotating and telescopic thrust adjustment mechanisms that automatically balance the aircraft by shifting the position of the propellers at the ends.

When surveying equipment is mounted on a drone and moved, the center of gravity shifts. Conventional drones have fixed propeller positions, forcing them to compensate solely by adjusting motor RPM. This leads to unstable hovering and rapid battery depletion, as motors must run at high speeds for extended periods to maintain balance.

This technology uses a horizontal controller to manage the rotation range, length, and motor RPM of the thrust adjustment mechanism based on the center of gravity shift caused by the movement of the surveying tool. It consists of first and second motors, a threaded rotating shaft, a telescopic adjustment unit, and a telescopic arm that repositions the propellers, supported by an anti-sagging member. Ideal for precision surveying drones, industrial multicopters carrying heavy equipment, and inspection or surveillance missions requiring long-duration hovering, it ensures stable, vibration-free flight while reducing motor load to extend battery life.

Key Features:

• Surveying position adjustment mechanism including a horizontal guide installed across the drone body and a support pole mounted vertically to move along the guide
• Thrust adjustment mechanism installed on a drone body capable of stable hovering via built-in sensors, featuring rotating and telescopic arms with propellers at the ends
• Horizontal controller that manages the rotation range, length, and motor RPM of the thrust adjustment mechanism based on center of gravity shifts caused by the movement of the surveying tool
• Telescopic adjustment unit coupled with the rotating shaft of the second motor, performing linear forward/backward motion as the shaft rotates, and connected to a telescopic arm equipped with a motor at the end
