Frequency-aware Decomposition Learning for Sensorless Wrench Forecasting on a Vibration-rich Hydraulic Manipulator

Researchers have developed a Frequency-aware Decomposition Network (FDN) to predict force and torque without physical sensors in robots performing rapid interaction tasks that induce high-frequency vibrations. This advancement is crucial for developers as it enhances the accuracy of sensorless wrench forecasting, especially in challenging environments like grinding operations, by leveraging spectral decomposition and adaptive filtering techniques.
