Solution Overview

Problem

The time-consuming and labor-intensive process of teaching robotic arms to handle multiple plate positions in automated workflows, particularly those requiring high precision, necessitates a more efficient method for acquiring teaching results across multiple operation stations.

Innovation Solution

A robot teaching method that determines target operation stations, acquires a first teaching result, and calculates a second teaching result for other stations based on the first result and arrangement information, reducing the need for repetitive manual teaching by using linear regression formulas and multivariate methods.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the robotic arm is taught to accurately handle each plate position individually, then the precision of grabbing and placing actions is improved, but the teaching time and effort increase significantly

Engineering Contradiction:
Improveprecision of grabbing and placing actionsVSAvoidteaching time and effort
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent segments the teaching process into two parts: first teaching the robotic arm the motion trajectory from the initial position to the target position (common path), and then separately teaching the grabbing and placing actions at each plate position. This segmentation allows the common motion path to be taught once and reused, reducing overall teaching time while maintaining precision for each individual plate position

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent performs preliminary teaching of the motion trajectory and path planning before teaching the specific grabbing and placing actions for each plate position. By establishing the common motion framework in advance, the system reduces the amount of repetitive teaching needed for each individual plate position while ensuring accurate positioning

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If the robotic arm operates at a large number of plate positions, then the automation capability is improved, but the teaching workload increases significantly

Engineering Contradiction:
Improveautomation capability for multiple plate positionsVSAvoidteaching workload
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent creates a universal teaching framework where the motion trajectory, path planning, and coordinate transformation methods can be applied to any number of plate positions. By teaching the robotic arm to understand the relationship between the initial position, target position, and plate positions along the motion path, the system achieves versatility for handling multiple plate positions without proportionally increasing teaching workload

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A robot teaching method and apparatus, an electronic device, and a storage medium. The method is used for teaching a robot of which the operation range can cover a plurality of operation stations, wherein the plurality of operation stations are configured to store operation objects. The method comprises: determining target operation stations specified by a user, wherein the target operation stations are some of the plurality of operation stations; teaching the robot on the basis of the target operation stations to obtain a first teaching result; and according to the first teaching result and arrangement information of the plurality of operation stations, obtaining a second teaching result of the other operation stations different from the target operation stations among the plurality of operation stations. After teaching is performed for some of operation stations, a teaching result of the other operation stations can be calculated, thereby effectively reducing the workload of robot teaching and the consumed time, and improving the efficiency of robot teaching.
