Researchers propose an Adaptive Gaussian Mixture Models-based Anomaly Detection system for Cable-Driven Parallel Robots without additional sensors.
The system uses motor torque data to detect anomalies that could affect robot performance during load manipulation tasks with predefined toolpaths.
An adaptive, unsupervised outlier detection algorithm based on Gaussian Mixture Models is employed, showing high accuracy in detecting anomalies with minimal latency.
Validation tests demonstrate a 100% true positive rate, 95.4% average true negative rate, and increased robustness compared to other detection methods.
