Method and Apparatus for Controlling the Movement of Multiple Robots Based on a Wireless Network

This technology is a multi-robot control system based on a WPAN wireless network that performs auto-spacing and cooperative localization through a master-slave architecture. The master robot receives commands from a central controller and retransmits them to slave robots or issues self-generated commands, while the slave robots control their real-time movement based on the received commands and distance information.

When controlling multiple mobile units simultaneously in environments with poor communication infrastructure, such as disaster sites, there have been challenges regarding communication range limitations, radio frequency interference, and ensuring the sequentiality and accuracy of control signals.

This technology utilizes the WPAN (IEEE 802.15.4a) wireless protocol to establish a network between multiple robots and implements a distance-based control algorithm that measures distance information from other robots in real-time upon receiving an auto-spacing command, executing movement commands only when the distance exceeds a set value. It can be applied to industrial robots and automated systems, improving the control of multiple mobile units by enabling efficient communication and coordination between the robots and the central controller.

Key Features:

• A device that moves based on a wireless network, characterized in that a movement control unit executes a movement command when the received distance information is greater than the auto-spacing setting.
• A transceiver unit that receives commands for controlling the movement of a slave robot as wireless network communication data
• A command preprocessing unit that extracts commands from the decrypted wireless network communication data
• A network control unit that decrypts the received wireless network communication data
