Solution Overview
Problem
Existing control systems for mobile objects fail to accurately detect objects, particularly those like poles or fences, which are difficult to detect without changing the posture or position of distance measuring devices.

A control device and method that includes a distance measuring device, a support device, and a controller to adjust the posture or position of the device to improve detection accuracy by emitting electromagnetic waves from different angles and positions, including upward and downward directions, to comprehensively irradiate target areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the distance measuring device maintains a fixed posture or position, then the device structure is simple and stable, but the detection accuracy for certain objects (like poles or fences) deteriorates
Solution Approach 1:
The support device enables the distance measuring device to dynamically adjust its posture and position between multiple predetermined states. The controller switches the support device between these states based on detection requirements, allowing the system to adapt from a fixed simple structure to a dynamic multi-state structure as needed.
Solution Approach 2:
The system changes the physical parameters (posture and position) of the distance measuring device by controlling the support device to transition between predetermined states. This parameter change enables the device to detect objects that were previously undetectable while maintaining overall system simplicity.
2Measurement precision
If the distance measuring device changes posture or position to detect hard-to-detect objects, then detection accuracy improves, but the response time and processing time increase
Solution Approach 1:
The controller pre-determines multiple predetermined states for the support device and prepares the system in advance. When object detection is needed, the controller can quickly switch between these pre-configured states rather than adjusting the device continuously or from scratch, reducing response time.
Solution Approach 2:
The system periodically switches the support device between predetermined states in a controlled sequence. This periodic switching allows the distance measuring device to systematically sample different detection angles and positions, improving detection accuracy while maintaining a regular, predictable time pattern that minimizes total response time.

AI summary
A control device includes: a distance measuring device that detects an object; a support device that supports the distance measuring device; and a controller configured to detect a prescribed object and to control a state of the support device. When the object has been detected, the controller is configured to cause the distance measuring device to emit electromagnetic waves in a state in which the distance measuring device is supported in a first posture or at a first position and then to cause the distance measuring device to emit electromagnetic waves in a state in which the distance measuring device is supported in a second posture or at a second position to which a direction or a position of the distance measuring device changes in at least one of an upward direction and a downward direction from the first posture or the first position.
