Error detection for painting robots

With the help of log data, two concrete error patterns are modeled and a procedure for identifying the errors is developed.

Challenge

A software house plans to expand the monitoring software of painting robots of a machine manufacturer to include a component for the early detection of errors. To prove the functionality of early detection in a proof of concept, the software vendor needs working detection models.

Solution

A use case workshop is conducted together with the software vendor’s data science team. In this process, significant variables for the error patterns are developed on the basis of the log data (feature engineering). Afterwards, classification models for the detection of error patterns and evaluation of the methods are estimated. On this basis, the steps required for the implementation are described.

Result

The customer can demonstrate the performance of the component to his machine manufacturer using the proof of concept. The software developers have concrete instructions for implementing the error detection.
