Autonomous Moving Body Obstacle Projection for Pedestrian Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous delivery systems do not effectively alleviate anxiety among persons regarding the detection of obstacles by moving bodies, such as delivery vehicles, during their movement.
Innovation Solution
A moving body equipped with a peripheral information detection sensor and a control section that autonomously travels and displays information about detected obstacles in its surroundings, including relative positions and planned movement directions, using a projection device to project images onto a road surface, allowing persons to be aware of potential obstacles and the moving body's trajectory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If autonomous traveling is implemented without peripheral obstacle display, then automation level is improved, but psychological safety of surrounding persons deteriorates
Solution Approach 1:
The system provides visual feedback to surrounding persons by displaying detected peripheral obstacles on the outer surface of the main body section. This feedback mechanism allows persons to understand what the autonomous vehicle has detected, reducing anxiety while maintaining automation.
Solution Approach 2:
The display section acts as an intermediary between the autonomous vehicle's detection system and surrounding persons. It translates sensor data into visible information that persons can understand, bridging the gap between automated operation and human awareness.
2Device complexity
If display area is limited to vehicle surface, then device complexity is reduced, but information visibility deteriorates
Solution Approach 1:
The system extends the display area from the two-dimensional vehicle surface to include the ground surface below. By projecting obstacle information onto the ground, the system effectively increases the display area without adding complex display hardware to the vehicle itself.

AI summary
A moving body includes: a main body section provided with a moving mechanism; a peripheral information detection sensor configured to detect an obstacle peripheral to the main body section; and a control section configured to cause the main body section to autonomously travel by controlling the moving mechanism based on information regarding the peripheral obstacle detected by the peripheral information detection sensor, and configured to cause information relating to the peripheral obstacle, in a direction of progress of the main body section, to be displayed in a surrounding area of the main body section.
