Digital Twin Driven Predictive Maintenance for High-Precision Agricultural Machinery

Joint degradation is a key factor limiting the performance of parallel kinematic robots like the Jaetrobi, developed at Leibniz Institute for Agricultural Engineering and Bioeconomy (ATB) for automatic, herbicide-free weeding using a laser. This work will focus on evaluating the long-term precision of Jaetrobi’s actuation system using a dedicated test rig with identical laser kinematics, which enables repeatable simulation of wear through defined motion patterns. Detailed analysis of joint fatigue and wear propagation will be applied toward a digital twin model that quantifies wear per movement and estimates component end-of-life. This predictive maintenance approach will support wear-optimized motion strategies, enabling synchronized joint replacement and thereby minimizing operational downtime and improving overall system reliability.
