This paper presents a novel method— asymmetric dual-user shared control method to enhance the variety of the training mode and improve the flexibility of the dual-user tele-manipulation process. Firstly, we model the novel dual-user shared control architecture with multi-dominance factors and analysis the relationship between the proposed method and the original one. Then, several performance measuring...
Time delay in bilateral teleoperation is a challenging problem from the point of view of both system stability and transparency. Traditional wave variable based teleoperation method can theoretically guarantee system passivity with arbitrary large time delay but cannot provide good position and force tracking performance. In this paper, a novel wave variable teleoperation structure is firstly proposed...
This paper studies analysis of bilateral control system with time delay based on mechanical power factor (MPF) concept. MPF is an interesting and useful performance index for evaluation of motion control systems. In this paper, first, effect of time delay and the effectiveness of a time-delay compensation method by using communication disturbance observer (CDOB) in bilateral control systems are analyzed...
This paper proposes a two channel control architecture based on impedance transmission in time delayed teleoperation system. In conventional research, bilateral teleoperation is widely researched and bilateral control is used to obtain remote force imformation. However the performance is degraded and destabilized by time delay. Conventional approaches like smith predictor, communication disturbance...
Performance indices are useful as design guidelines of control systems. One of useful performance indices for bilateral teleoperation systems is transparency. It evaluates bilateral teleoperation systems based on a definition of the ideal state of bilateral control. Since the concept is intuitive, it has been widely used in many applications. The evaluation or analysis based on transparency is usually...
Force-reflecting teleoperators in which the remote environment is kinesthetically coupled to the operator can considerably increase task performance. Wave-variable-based controllers can support the stable operation of force-reflecting teleoperators under arbitrary communication delays. Transparency in such systems is compromised in order to maintain stability. We had previously proposed a modified...
In this paper, the impedance perceived by an operator of a robot in multilateral control system under constant communication time delay is considered. The multilateral control system is one of the methods which transmit tactile sense to many remote places. Time delay possibly makes the performance of the multilateral control system worse. For example, time delay makes an operator feels large operational...
