| contents | Over eleven years into its mission, the Mars Science Laboratory remains vital to NASA's Mars exploration. Safeguarding the rover's long-term functionality is a top mission priority. In this study, we introduce and test undercomplete autoencoder models for detecting drive anomalies, using telemetry data from wheel actuators, the Rover Inertial Measurement Unit (RIMU), and the suspension system. Our approach enhances post-drive data analysis during tactical downlink sessions. We explore various model architectures and input features to understand their impact on performance. Evaluating the models involves testing them on unseen data to mimic real-world scenarios. Our experiments demonstrate the undercomplete autoencoder model's effectiveness in detecting drive anomalies within the Curiosity rover dataset. Remarkably, the model even identifies subtle anomalous telemetry patterns missed by human operators. Additionally, we provide insights into optimal design choices by comparing different model architectures and input features. The model's ability to capture inconspicuous anomalies, potentially indicating early-stage failures, holds promise for the field, by improving the reliability and safety of future planetary exploration missions through early anomaly detection and proactive maintenance. |
