New AI model enhances robotic force estimation in high-frequency tasks

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a Frequency-aware Decomposition Network (FDN) to improve sensorless estimation of high-frequency forces and torques in robotic contact tasks. This method spectrally decomposes the wrench horizon into low-frequency and high-frequency components, estimating each separately. FDN demonstrated a 47% reduction in high-frequency amplitude error on real-world grinding data compared to existing methods, while also maintaining competitive low-frequency accuracy and estimating a 1,000 ms horizon within 11 ms on a single CPU thread. AI

IMPACT This AI model could enable more precise and responsive robotic control in high-speed, high-impact manufacturing and manipulation tasks.

    Frequency-aware decomposition learning for sensorless wrench estimation in vibration-rich robotic contact

    arXiv:2604.12905v2 Announce Type: replace-cross Abstract: Force and torque (F/T) sensors enable contact-aware control by providing reactive feedback, but they are often fragile and expensive. To overcome these limitations, sensorless methods estimate F/T or wrench solely from rob…
