Multibody multipole methods [PDF]

Journal of Computational Physics, 2012
A three-body potential function can account for interactions among triples of particles which are uncaptured by pairwise interaction functions such as Coulombic or Lennard-Jones potentials. Likewise, a multibody potential of order $n$ can account for interactions among $n$-tuples of particles uncaptured by interaction functions of lower orders. To date,

Improved Motion Classification With an Integrated Multimodal Exoskeleton Interface

Frontiers in Neurorobotics, 2021
Human motion intention detection is an essential part of the control of upper-body exoskeletons. While surface electromyography (sEMG)-based systems may be able to provide anticipatory control, they typically require exact placement of the electrodes on ...

Novel SPECTA Actuator to Improve Energy Recuperation and Efficiency

Actuators, 2022
The current state of the art in compliant actuation has already good performance, but this is still insufficient to provide a decent autonomy for the next generation of robots. In this paper, a next step is taken to improve the efficiency of actuators by

A Screw-Axis Approach to the Stability of Two-Wheeled Vehicles

Applied Sciences, 2021
The stability of two-wheeled vehicles is predominantly characterized by the well-known weave and wobble vibration modes, which have been extensively investigated in the literature, mainly in terms of their frequencies and damping ratios. In this work the

An intern-sufficient cloud for large-scale multi-robot systems and its application in multitarget navigation

International Journal of Advanced Robotic Systems, 2021
Due to generally limited computing capability of an individual robot, cloud-based robotic systems are increasingly used. However, applications in large-scale multi-robot systems will be hindered by communication congestion and consequent lack of ...
