Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flying objects face instability and high energy consumption when performing fine sensing tasks, especially at low altitudes, and are affected by vibrations during high-magnification sensing, making them unsuitable for detailed observations.
Innovation Solution
A sensing system comprising a flying object for comprehensive sensing and a ground vehicle for fine sensing, where the flying object acquires initial data, identifies target areas, and a ground vehicle moves to those areas for detailed observation, allowing for both wide-area and precise data collection without the need for low-altitude flying or high-magnification sensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a flying object flies at low altitude to perform fine sensing, then sensing precision is improved, but stability deteriorates due to ground effect
Solution Approach 1:
The sensing task is segmented into two stages: first, a flying object performs wide-area comprehensive sensing from the sky; second, a ground traveling object performs fine sensing at the extracted target area. This segmentation allows each object to operate in its optimal stability condition while achieving both comprehensive and fine sensing goals.
Solution Approach 2:
The flying object acts as an intermediary that performs preliminary wide-area sensing and extracts target areas, then guides the ground traveling object to those areas. This intermediary role eliminates the need for the flying object to perform unstable low-altitude fine sensing while still enabling fine sensing through the ground object.
2Measurement precision
If a flying object flies at low altitude for fine sensing, then sensing precision is improved, but energy consumption increases
Solution Approach 1:
The sensing mission is divided into wide-area sensing by the flying object and fine sensing by the ground traveling object. The flying object operates at stable high altitude consuming less energy, while the ground object handles the energy-intensive fine sensing task at the target area, overall reducing total energy consumption.
Solution Approach 2:
The flying object performs only partial sensing (wide-area comprehensive sensing) rather than attempting complete fine sensing, extracting target areas to guide the ground object. This partial action by the flying object combined with ground-based fine sensing reduces overall energy consumption while achieving fine sensing precision.
3Measurement precision
If high magnification sensor is used for fine sensing from sky, then sensing precision is improved, but vibration influence increases
Solution Approach 1:
The sensing function is segmented between aerial and ground platforms. The ground traveling object performs fine sensing at the target area, eliminating vibration issues associated with aerial high-magnification sensing while maintaining high precision through close-proximity ground-based observation.
Solution Approach 2:
The ground traveling object serves as the intermediary that actually performs the fine sensing task at the target area, removing the harmful vibration factor from the sensing process while the flying object continues to provide wide-area coverage and target area extraction.
4Area of stationary object
If comprehensive wide-area sensing is performed, then coverage area is improved, but fine sensing capability deteriorates
Solution Approach 1:
The sensing operation is segmented into two phases: wide-area comprehensive sensing by the flying object to cover large areas, followed by fine sensing by the ground traveling object at extracted target areas. This segmentation enables both large coverage and high precision without compromise.
Solution Approach 2:
The flying object performs preliminary wide-area sensing and extracts target areas before the ground traveling object arrives for fine sensing. This preliminary action enables efficient task allocation, allowing the ground object to focus only on areas requiring fine sensing, thus achieving both wide coverage and fine detail.

AI summary
The sensing system S extracts a target area to be subjected to short-distance sensing by the UGV 2 on the basis of the long-distance sensing data obtained by the UAV 1 in the air performing long-distance sensing on a lower place, perform movement control for moving the UGV 2 toward the target area. And then, the sensing system S acquires short-distance sensing data obtained by performing short-distance sensing on the whole or a part of the target area by the UGV 2 that has moved according to the movement control.
