Swarm robots and a method for configuring them on a large scale

Swarm Robotics

This technology measures the distance between three RF nodes arranged in an equilateral triangle on the top plate of a master robot and the RF node of a slave robot. By rotating the top plate, it identifies the point where the distances between specific nodes on the master robot and the slave robot become equal, then calculates the relative position of the slave robot using the resulting geometric triangulation and rotation angle.

Conventional technologies for swarm robot localization require the installation of expensive infrastructure or complex sensing devices, such as gyro and ultrasonic sensors, on each individual robot, leading to high data processing loads and increased system costs.

This technology equips the master robot with a rotating top plate and three RF nodes arranged in an equilateral triangle, while minimizing the hardware on the slave robot to just an RF node. Based on the rotation of the master robot's top plate and the distance information between nodes, the master robot precisely calculates the slave robot's position and issues formation commands. Applicable to robot gripping, precision measurement, and automated facilities, this approach minimizes data processing and hardware requirements for a large number of slave robots, thereby reducing overall system load and construction costs.

Key Features:

• A control module that determines the position of the slave robot based on its current location.
• A current position detection module that detects the current location.
• A top plate rotation motor and rotation unit that rotates the top plate.
• A swarm robot characterized by an RF node installed at the center of the top plate that communicates with the first and second RF nodes of the master robot.
