Robot Operation Adjustment Using Synchronized Vision Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is challenging for operators to visually confirm and adjust the operation of high-speed robots, leading to difficulties in ensuring accurate operation and synchronization of robot and tool movements, resulting in potential misalignment or improper handling of workpieces.
Innovation Solution
An operation adjustment apparatus equipped with a high-speed camera and controller processes images to determine if the robot and tool operations are as intended, correcting operation commands in real-time to align with predetermined operations, ensuring accurate timing and positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the robot operates at high speed to improve productivity, then the production efficiency increases, but it becomes difficult for operators to visually observe and confirm the robot's operation state
Solution Approach 1:
The patent introduces a camera as an intermediary device to capture images of the robot's operation state. The camera system acts as a mediator between the high-speed robot and the operator, allowing the operator to observe the robot's position and operation through captured images rather than direct visual observation, thereby resolving the contradiction between high-speed operation and visual observability
Solution Approach 2:
The patent creates a visual copy of the robot's operation state through camera imaging. By capturing and displaying images of the actual robot position and operation, the system provides an indirect visual representation that allows operators to monitor high-speed operations without needing to directly observe the fast-moving robot, thus solving the observation difficulty at high speeds
2Productivity
If the robot operates at high speed, then productivity improves, but the positioning accuracy and operation precision deteriorate
Solution Approach 1:
The patent implements a feedback mechanism where camera-captured images of the robot's actual position are fed back to the control system. The control system compares the actual position with the target position, detects deviations, and automatically corrects the operation commands to maintain positioning accuracy even at high operation speeds
Solution Approach 2:
The system performs self-correction of positioning deviations through automatic feedback control. The control apparatus autonomously detects positioning errors via image processing and adjusts operation parameters without external intervention, enabling the robot to maintain precision during high-speed autonomous operation
3Productivity
If the robot operates at high speed, then productivity increases, but the operation adjustment capability deteriorates
Solution Approach 1:
The patent replaces manual operation adjustment with an automated control system that uses image processing and feedback algorithms. Instead of operators manually observing and adjusting high-speed robot operations, the system automatically captures images, processes them to detect position deviations, and generates corrected operation commands, thereby maintaining ease of operation at high speeds

AI summary
An operation adjustment apparatus includes a camera arranged so as to capture images of a robot and a hand. The robot controller includes an operation control unit that sends an operation command to the robot at a predetermined control cycle. The camera captures images at a time interval that coincides with the control cycle. A determination unit of the robot controller determines whether an operation of the hand is appropriate based on a result of image processing performed by an image processing unit. If the determination unit determines that the operation of the hand is not appropriate, a correction unit of the robot controller corrects a command statement included in an operation program so that the operation of the hand is an appropriate operation.
