Resilient Navigation for Autonomous Farm Robots by Leveraging Jerk-Augmented Models with IMU-Only Disturbance Rejection

Precise state estimation for navigation of autonomous agricultural robots is often compromised by sensor outages (GNSS/LiDAR/Visual) and high-frequency vibrations inherent in off-road environments. This paper proposes a robust navigation algorithm based on a jerk-augmented Extended Kalman Filter (EKF) integrated with a Multiple Tuning Factor (MTF) adaptation method. Unlike standard EKF approaches that assume constant measurement noise, our method dynamically adjusts the measurement covariance matrix in real-time, allowing the system to cope with sudden disturbances and sensor outliers. We evaluate the algorithm using real-world data from a Salin247 autonomous robot. Results demonstrate that jerk-augmentation combined with MTF adaptation significantly reduces 3D position Root Mean Square Error (RMSE) compared to baseline EKF models, providing superior dead-reckoning capabilities.

A deep learning based solution for construction equipment detection: from development to deployment

This paper aims at providing researchers and engineering professionals with a practical and comprehensive deep learning based solution to detect construction equipment from the very first step of its development to the last one which is deployment. This paper focuses on the last step of deployment. The first phase of solution development, involved data preparation, model selection, model training, and model evaluation. The second phase of the study comprises of model optimization, application specific embedded system selection, and economic analysis. Several embedded systems were proposed and compared. The review of the results confirms superior real-time performance of the solutions with a consistent above 90% rate of accuracy. The current study validates the practicality of deep learning based object detection solutions for construction scenarios. Moreover, the detailed knowledge, presented in this study, can be employed for several purposes such as, safety monitoring, productivity assessments, and managerial decisions.
