Robot Camera Mount Offsets for Teaching-Free Imaging Repositioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-joint robot systems where multiple robots cooperate, changing the camera's attachment position requires significant operator effort due to changes in the positional relationship between the robot and camera, necessitating repetitive teaching processes.
Innovation Solution
A robot system that allows the camera's position on a multi-joint robot to be changed to multiple predetermined positions, with offset information stored in a memory device, enabling the control device to adjust the robot's arm based on this information for accurate imaging without operator intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera attachment position is changed to avoid interference with other robots, then the imaging capability is maintained, but the teaching process must be repeated which increases operator labor
Solution Approach 1:
Offset information between the robot arm and camera is measured and stored in advance for multiple predetermined camera attachment positions. When the camera is attached to a different position, the control device simply retrieves the corresponding pre-stored offset information and automatically adjusts the arm position, eliminating the need for repetitive teaching operations.
2Adaptability or versatility
If the camera attachment position is changed, then the positional relationship between robot and camera changes, but manual re-teaching is required which reduces productivity
Solution Approach 1:
Offset information for multiple camera attachment positions is pre-measured and stored in the memory device. When camera position changes occur, the control device automatically retrieves the appropriate offset data and adjusts the robot arm accordingly, reducing setup time and improving productivity without sacrificing adaptability.
3Adaptability or versatility
If multiple camera positions are supported, then the system becomes more versatile, but the control complexity increases
Solution Approach 1:
All offset information for multiple camera positions is pre-calculated and stored in the memory device during system setup. The control device simply retrieves the appropriate offset data based on the current camera attachment position and applies automatic position adjustment, managing control complexity while supporting multiple positions.

AI summary
The robot system for which the position of a camera attached to the arm is changeable to multiple positions. The robot system memorizes offset information between the arm and the camera for each of multiple positions. Further, the robot system moves the arm to the position offset by the offset information corresponding to the attachment position of the selected camera. As a result, even when the mounting position of the camera is changed, the robot system can move the camera to an appropriate position when imaging and perform imaging without requiring troublesome teaching.
