Assistive robot systems require a robot to interact closely with people and to perform joint human-robot tasks. Interaction with humans comes with additional challenges to those in other real-world scenarios. Robot plans must be especially flexible and take into account human abilities and preferences. For providing this level of flexibility, we propose a framework for transformational reactive...

recently a method has been developed to decouple the equations of motion for multi-rigid body systems. in this paper, the method is first studied, then the equations of motion for a planar two degree-of-freedom robot with flexible joints are carried out using lagaranges equations and kanes equation with congruency transformations. finally, the results obtained from both methods are throroughly ...

this paper studies the effect of flexible linear torso on the dynamics of passive quadruped bounding. a reduced-order passive and conservative model with linear flexible torso and springy legs is introduced. the model features extensive spine deformation during high-speed bounding, resembling those observed in a cheetah. fixed points corresponding to cyclic bounding motions are found and calcul...

In this paper we present a new approach for joint trajectory tracking of a single-link flexible robot manipulator. Firstly a distributed parameter dynamic model is derived using extended Hamilton Principle. Based on this model a new moment feedback trajectory tracking control scheme is designed for a single-link flexible robot manipulator having a payload at its free end. The control scheme is ...

-A flexible, real-time motor control system consisting of a DC motor and an incremental optical encoder is proposed. The system allows complex real-time control algorithms to be implemented with hardware control excepting PC-based software simulation. A motion control processor is used to bridge the Target PC and the robot joint through I/O devices. Simulink/Real Time Workshop (RTW) are the sof...

The upper limb exoskeleton rehabilitation robot can realize the partial functional compensation of and complete various types training for each joint limb. However, existing robots are lack flexible reconfigurability, which difficult to meet diversified patient objects needs, have some problems, such as insufficient motion compliance, poor portability, wearing comfort. To effectively solve abov...

Minimally invasive surgery systems typically involve thin and cabledriven surgical instruments. This introduces link and joint flexibility in the slave robot of a master-slave teleoperation system, reducing the effective stiffness of the slave and the transparency of teleoperation. In this paper, we analyze transparency under slave link and joint flexibility (tool flexibility). We also evaluate...
