Robot Arm Camera Teaching for Precise Remote Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robot teaching operations require direct interaction with the robot and its workspace, making it cumbersome and mentally burdensome for operators, especially when the working space is isolated or cluttered, as they need to adjust their posture and position to align the robot arm with the task object accurately.
Innovation Solution
A robot operating device equipped with a camera attached to the robot arm, a display, and an operation-accepting unit that allows operators to perform teaching operations by interacting with the image displayed on the screen, enabling them to guide the robot arm through touch, jog button, or joystick operations, allowing precise positioning and orientation of the robot arm relative to the task object without physical proximity.

Engineering Contradiction Analysis
1Measurement precision
If operators perform direct teaching operations by interacting with the robot and its workspace, then the robot can be taught motions according to task details, but the operation becomes cumbersome and mentally burdensome, especially when the working space is isolated or cluttered
Solution Approach 1:
A camera is introduced as an intermediary device to capture images of the workspace and task objects. The camera transmits visual information to a display device, allowing operators to view the workspace remotely without physical proximity. This intermediary system enables precise positioning by displaying the task object and robot arm position on screen, while eliminating the need for operators to physically navigate cluttered or isolated working spaces.
Solution Approach 2:
The camera creates a visual copy (image) of the physical workspace and task objects. This copied visual representation is displayed on a display device, allowing operators to interact with the robot teaching process by viewing the copied scene rather than the physical scene directly. The operation-accepting unit then translates operator inputs into robot movements based on this visual copy, maintaining positioning precision while improving operational ease.
2Measurement precision
If operators need to align the robot arm with the task object accurately in isolated or cluttered environments, then positioning precision can be achieved, but operators must adjust their posture and position frequently, increasing mental burden
Solution Approach 1:
The camera serves as a mediator that provides a stable visual reference of the workspace and task object position. Operators can view the aligned state of the robot arm and task object on the display without needing to physically adjust their posture. The operation-accepting unit processes operator inputs based on this visual feedback, maintaining alignment precision while eliminating time lost to posture adjustments.
Solution Approach 2:
The system transitions from direct physical observation to remote visual observation through the camera and display. This dimensional shift allows operators to view the workspace from a comfortable distance while maintaining precise alignment control. The operation-accepting unit translates operator commands into robot arm movements that achieve accurate alignment with the task object based on the visual information from the camera, reducing time loss without compromising precision.
3Ease of operation
If a camera is attached to the robot arm to enable remote operation, then operators can interact with the displayed image for teaching operations, but the device complexity increases
Solution Approach 1:
The camera is designed to perform multiple functions: capturing images of the workspace, transmitting images to the display device, and providing visual feedback for the operation-accepting unit. The display device also serves dual purposes by showing both the camera feed and operational controls. This multi-functionality reduces the need for separate dedicated components, thereby managing system complexity while improving operational ease through remote interaction.
4Ease of operation
If operators use touchscreen interface to remotely align and position the robot arm, then mental strain is reduced and precision in task object placement is improved, but the device complexity increases
Solution Approach 1:
The system replaces direct mechanical interaction with the robot arm with a touchscreen interface that provides visual feedback and control. Operators interact with the displayed image of the workspace and robot arm position through touch gestures, which are then translated by the operation-accepting unit into precise robot arm movements. This substitution reduces mental strain by providing clear visual feedback and intuitive control, while the integrated camera-display-interface system manages complexity through unified design.

AI summary
A robot operating device includes a camera that is attached to a distal end of a robot arm or a position adjacent to the distal end and that acquires an image; a display which displays the image acquired by the camera; an operation-accepting unit which accepts an operation that is performed by an operator on the image displayed on the display unit; and a controller which moves the robot arm based on the operation accepted by the operation-accepting unit.
