Solution Overview
Problem
Existing radiation-based guiding systems for robots are prone to signal distortions, leading to incorrect paths and potential loss of robots, necessitating manual reconnection to the base station for charging.
Innovation Solution
A millimeter-wave positioning system and transmitter are used to determine the robot's position relative to the base station and emit a directional radar guiding signal, reducing signal distortions and ensuring accurate navigation to the charging station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If an undirected radiation signal is used for guiding the robot, then the robot can be guided within a larger coverage area, but the signal is more prone to distortions and interferences causing the robot to follow wrong paths
Solution Approach 1:
The patent combines two previously separate functions into a unified system: (1) a millimeter-wave positioning system that determines the robot's position relative to the base station, and (2) a transmitter that emits directional radar guiding signals steered toward the robot's position. This integration allows the system to maintain large coverage while ensuring reliable guidance by continuously adapting the signal direction to the robot's actual position.
Solution Approach 2:
The patent transforms the static undirected radiation signal into a dynamic directional signal that is continuously steered toward the robot's current position. The transmitter adjusts the beam direction in real-time based on position data from the millimeter-wave positioning system, making the guiding signal adaptive and resilient to distortions while maintaining coverage.
2Reliability
If a directional radar guiding signal is emitted towards the robot's position, then signal distortions and interferences are reduced, but the system requires continuous position determination and signal steering
Solution Approach 1:
The patent makes the millimeter-wave positioning system serve dual functions: (1) determining the robot's position for navigation purposes, and (2) providing the positional data needed to steer the directional guiding signal. This multi-functionality reduces the need for separate systems while achieving both position tracking and reliable directional guidance.
Solution Approach 2:
The system implements a feedback loop where the millimeter-wave positioning system continuously monitors the robot's position, and this position information is fed back to the transmitter to adjust the steering of the radar guiding signal. This closed-loop control ensures the signal remains directed at the robot despite movements or environmental factors.
3Ease of operation
If the robot follows an incorrect path due to signal distortions, then the robot may get lost and require manual reconnection to the base station, but preventing this requires more sophisticated guiding mechanisms
Solution Approach 1:
The patent enables the robot to autonomously navigate to the base station using the directional radar guiding signal without requiring manual intervention. The system continuously steers the signal toward the robot's position, allowing the robot to self-correct its path and autonomously return to the base station even if distortions occur, eliminating the need for manual reconnection.
