Solution Overview
Problem
In remote control robot systems with multiple cameras, adjusting the camera switching timing for accurate spatial relationship understanding between the work object and robotic arm is cumbersome and requires preadjustment, making it difficult to adapt to changes in the work environment.
Innovation Solution
A remote control robot system that includes a robotic arm, a remote control device, multiple cameras, a monitor, a camera selecting device, a storage device, and an image processor, allowing for automatic switching of camera images based on operator selection or pre-stored information, enabling flexible and adaptive camera switching without prior adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple cameras are used to image the work environment, then the operator can accurately grasp the spatial relationship between the work object and the robot, but the adjustment of camera switching timing becomes troublesome and time-consuming
Solution Approach 1:
The system uses the robot's own operation state information to automatically control camera switching. The storage device stores correspondence between robot operation states and camera selections, and the image processor automatically switches cameras based on current operation state, making the system self-regulating without operator intervention.
Solution Approach 2:
The system establishes a feedback loop where the robot's operation state is continuously monitored and fed back to the image processor, which then selects the appropriate camera. This closed-loop control ensures the displayed image always corresponds to the current operation phase.
2Adaptability or versatility
If manual adjustment of camera switching timing is required, then the system can adapt to different work scenarios, but the operator burden increases and readjustment is needed when work changes
Solution Approach 1:
The system pre-stores the correspondence between robot operation states and optimal camera selections in the storage device. This preliminary preparation allows the system to automatically adapt to different work scenarios without requiring real-time manual adjustment when work changes occur.
3Ease of operation
If camera switching is automated based on robot operation state, then the operator burden is reduced and real-time adjustment is enabled, but the system complexity increases
Solution Approach 1:
The image processor performs multiple functions: it processes images from multiple cameras, determines robot operation state, selects appropriate cameras based on stored correspondence, and outputs images to the display device. This multi-functionality reduces the need for separate dedicated components.
