Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robot control systems lack an efficient mechanism for a master robot to control multiple slave robots and create obstacle-avoiding paths, limiting their ability to navigate complex environments effectively.
Innovation Solution
A master robot equipped with a communication unit, sensing units, and a control module that creates a space map to guide slave robots, allowing for efficient control and obstacle avoidance by receiving move commands and using cameras and sensors to monitor and adjust the robots' movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If one robot controls multiple slave robots, then robot control efficiency is improved, but device complexity increases
Solution Approach 1:
The control system is segmented into a master robot with full control capabilities and multiple slave robots with simplified control functions. The master robot contains the control module that creates space maps and generates movement paths, while slave robots only need to execute commands, dividing the control complexity from the execution complexity.
Solution Approach 2:
The master robot acts as an intermediary between the control system and slave robots. It receives movement commands, creates space maps of the environment, determines optimal paths, and transmits control signals to slave robots, mediating the complexity of environment perception and path planning away from the slave robots.
2Speed
If a master robot creates space maps to guide slave robots, then navigation speed is improved, but measurement precision requirements increase
Solution Approach 1:
The master robot performs preliminary actions by creating a complete space map of the environment before slave robots begin their tasks. This pre-mapping allows slave robots to quickly navigate using the pre-established map and pre-calculated paths, rather than requiring them to perform real-time mapping, thus improving navigation speed.
3Reliability
If the master robot monitors slave robot movement to avoid obstacles, then reliability is improved, but use of energy increases
Solution Approach 1:
The master robot creates a copied representation of the environment through space maps and uses this copy to plan obstacle-free paths for slave robots. Instead of requiring continuous real-time monitoring of slave robot positions and obstacle detection, the system uses the pre-created space map copy to generate safe movement paths, reducing the energy required for continuous monitoring while maintaining reliability.

AI summary
Disclosed is a master robot for controlling at least one slave robot. The master robot includes a communicator that communicates with the slave robot or a mobile terminal, at least one sensor, an inputter that inputs an image signal or an audio signal, and a controller that creates a space map corresponding to a predetermined space in which the master robot and the slave robot are located on the basis of information sensed by the sensor or information inputted through the inputter. Accordingly, a master robot equipped with artificial intelligence and a 5G communication module can be provided.
