Moving Body Stop Control Using Flat Surface Safety Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous moving bodies, such as drones and vehicles, face challenges in safely stopping on suitable flat surfaces, as existing technologies do not effectively assess the safety of landing or stopping locations, potentially leading to accidents due to inclined or unsuitable ground conditions.
Innovation Solution
A moving body equipped with a safety degree calculation unit and movement control unit that assesses the safety of flat surfaces based on sensor data, calculating a safety degree index to guide the movement to the most suitable flat surface for stopping, using a combination of sensor data, flat surface information, and external environment data to ensure safe landing or stopping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the moving body autonomously moves without using safety degree calculation, then the device complexity is reduced, but the reliability of safe stopping is worsened
Solution Approach 1:
The safety degree calculation unit performs preliminary assessment of the stopping surface before the moving body actually stops. It calculates safety degree based on flat surface information obtained from sensors, evaluating whether the surface is suitable for safe stopping in advance, thus preventing unsafe stops before they occur.
Solution Approach 2:
The safety degree calculation unit acts as an intermediary between the sensor that detects flat surface information and the movement control unit that executes stopping. It processes the raw sensor data into a meaningful safety degree metric that guides the movement control decisions, enabling safe stopping without direct complex sensor-to-control coupling.
2Reliability
If the moving body uses safety degree calculation based on flat surface information, then the reliability of safe stopping is improved, but the loss of information is worsened
Solution Approach 1:
The movement control unit uses the calculated safety degree as feedback to adjust the stopping decision. The safety degree calculation unit continuously monitors flat surface information and provides updated safety assessments, allowing the moving body to adapt its stopping behavior based on real-time surface conditions.
3Reliability
If the moving body autonomously selects stopping location without safety assessment, then the productivity is improved, but the reliability of safe stopping is worsened
Solution Approach 1:
The safety degree calculation is performed in advance during the movement process, allowing the moving body to identify suitable stopping locations before reaching them. This preliminary assessment enables efficient route planning and stopping decisions without requiring post-arrival evaluation or multiple retry attempts.
