Autonomous Loading of Fragmented Rock: Admittance Control for Robotic Digging
An admittance-based controller for autonomously digging in fragmented rock piles was developed and tested by using a 1 t surface loader, and a 14 t Atlas Copco Load-Haul-Dump (LHD) vehicle. This admittance-based Autonomous Loading Controller (ALC) had superior consistency over both digging at …

Realization of dynamixel servo plant parameters to improve admittance control for a compliant human-robot interaction
In theory, admittance control offers a very effective method of implementing smooth human-robot interaction. It allows the user's applied force to control the movement of a powerful robot as if the robot were a small, passive mass. However, the real-world application of admittance control faces …

Green's function derivations for specific acoustic admittances and impedances
Impedance and admittance relationships in acoustics are commonly given in their frequency-domain representations. This is done for many reasons including the simplicity of the mathematics used to compute frequency-domain impedance functions. However, although the frequency-domain representations of …

Piezoelectric active sensor and electric impedance approach for structural dynamic measurement
… structural information by measuring the electric admittance of the sensors. Because of the electromechanical coupling, the electric admittance is mechanically modulated by the structural dynamics through the piezoelectric effect. The structural dynamic characteristics can then be extracted using a …
