Guide Robot Path Projection for Pedestrian Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Guide robots face issues such as unpredictable obstacle avoidance leading to collisions and inefficient path selection due to lack of visible movement direction, and sudden movements causing accidents with unaware individuals.
Innovation Solution
A guide robot equipped with a signal receiving unit, controller, and light emitting module that calibrates its moving region by determining region calibration parameters based on movement instructions, using light displays to visibly indicate its movement path and trend, thereby preventing collisions and improving navigation efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the guide robot uses sensor-based obstacle avoidance, then it can automatically avoid obstacles, but it causes unpredictable avoidance direction leading to multiple mutual avoiding events and extended operation time
Solution Approach 1:
The patent applies preliminary action by displaying the robot's movement trajectory in advance through light emitting modules before the robot actually moves. This allows pedestrians to see the future path and avoid the robot proactively, preventing multiple mutual avoiding events. The trajectory display is configured ahead of time based on the navigation path, enabling pedestrians to take preventive action rather than reacting to sudden robot movements.
2Productivity
If the guide robot moves suddenly from static state, then it can reach destination efficiently, but it causes collision with unaware pedestrians
Solution Approach 1:
The patent displays the movement trajectory using light emitting modules before the robot begins moving. This preliminary visual warning allows pedestrians to become aware of the robot's intended motion and adjust their behavior accordingly, preventing collisions while maintaining efficient movement. The trajectory is calculated and displayed in advance based on navigation instructions.
Solution Approach 2:
The patent uses different light colors to indicate different movement states and trajectory information. The light emitting modules can display various colors to represent different aspects of the movement path, such as warning zones, safe zones, or different types of obstacles, providing intuitive visual information to pedestrians about the robot's intentions and helping them avoid collisions.
3Object-affected harmful factors
If the guide robot displays movement trajectory in advance, then it prevents collisions and improves safety, but it requires additional light emitting modules and control complexity
Solution Approach 1:
The patent makes the light emitting modules serve multiple functions: they display the movement trajectory, indicate warning zones, show navigation status, and provide visual feedback about the robot's state. This multi-functionality reduces the need for separate components and justifies the added complexity by consolidating multiple information delivery functions into a single system.
Solution Approach 2:
The light emitting modules act as an intermediary between the robot's navigation system and pedestrians. Instead of pedestrians directly observing robot movements or receiving complex sensor data, the light modules translate navigation information into intuitive visual displays that pedestrians can easily understand and react to, simplifying the interaction while improving safety.

AI summary
The disclosure discloses a method of calibrating a moving region of a guide robot. The method includes: detecting and receiving, by a signal receiving unit, a movement instruction, and sending the received movement instruction to a controller; determining, by the controller, region calibration parameters corresponding to the received movement instruction according to a predetermined mapping relation between the movement instruction and the region calibration parameters, wherein the region calibration parameters include a pending moving region of the guide robot, a light display parameter in the pending moving region, and a driving parameter corresponding to the pending moving region and the light display parameter; driving, by the controller, the light emitting module to carry out light display calibration in the pending moving region according to the determined region calibration parameters. The disclosure further provides the guide robot and a computer storage medium. The technical solution of the disclosure enables the guide robot to display a marked region to be passed and provide a visible movement trend prompt so as to avoid a phenomenon of collision or multiple times of avoiding between people and the robot.
