Nuclear spins interact weakly with their environment and therefore exhibit long coherence times. This has led to use as memory qubits in quantum information platforms, where they are controlled via electromagnetic waves. Scaling up such platforms comes challenges terms of power efficiency, well cross-talk between devices. Here, we demonstrate coherent control a single nuclear spin using surface...

This paper presents the practical implementation of an active force control (AFC) strategy to a laboratory scaled vibration isolator platform. The research was carried out to investigate the performance of vibration suppression capability of feedback controller using AFC. Two types of controller schemes were examined and compared involving the classic proportionalintegral-derivative (PID) contr...

We review the mechanical components of an approach to motion science that enlists recent progress in neurophysiology, biomechanics, control systems engineering, and non-linear dynamical systems to explore the integration of muscular, skeletal, and neural mechanics that creates effective locomotor behavior. We use rapid arthropod terrestrial locomotion as the model system because of the wealth o...

The goal of this chapter is to provide tools for analyzing and controlling nonholonomic mechanical systems. This classical subject has received renewed attention because nonholonomic constraints arise in many advanced robotic structures, such as mobile robots, space manipulators, and multifingered robot hands. Nonholonomic behavior in robotic systems is particularly interesting, because it impl...

In this paper, a passive bilateral control law is proposed for a teleoperator consisting of a pair of n-DOF nonlinear robotic systems. The control law ensures energetic passivity of the closed-loop teleoperator with power scaling, coordinates motions of the master and slave robots, and installs useful task-specific dynamics for inertia scaling, motion guidance and obstacle avoidance. Consequent...
