— If a teleoperation scenario foresees complex and fine manipulation tasks a multi-fingered telemanipulation system is required. In this paper a multi-fingered telemanipulation system is presented, whereby the human hand controls a three-finger robotic gripper and force feedback is provided by using an exoskeleton. Since the human hand and robotic grippers(More)
— Recent research focuses on developing robots that are meant to be partners of humans instead of pure machines. This makes enhanced communication necessary. Especially in scenarios embedding physical interaction between the two partners dominance is an urgent matter. To overcome one-sided dominance as in passive following or trajectory replay in favor of(More)
Recent developments strive for realizing robotic systems that not only interact, but closely collaborate with humans in performing everyday manipulation tasks. Successful collaboration requires the integration of the individual partner's intentions into a shared action plan, which may involve continuous negotiation of intentions. We focus on collaboration(More)
— Despite the great diversity of teleoperator designs and applications, their underlying control systems have many similarities. These similarities can be exploited to enable inter-operability between heterogeneous systems. We have developed a network data specification that can be used for Internet based control of a wide range of teleoperators. In this(More)
Goal-directed movements are executed under the permanent supervision of the central nervous system, which continuously processes sensory afferents and triggers on-line corrections if movement accuracy seems to be compromised. For arm reaching movements, visual information about the hand plays an important role in this supervision, notably improving reaching(More)
In the BEAMING project we have been extending the scope of collaborative mixed reality to include the representation of users in multiple modalities, including augmented reality, situated displays and robots. A single user (a visitor) uses a high-end virtual reality system (the transporter) to be virtually teleported to a real remote location (the(More)
— In a haptic teleoperation system, the incorporation of knowledge about the remote environment in the controller design can improve stability and performance. Model-mediated teleoperation adopts this idea by rendering an estimated model of the remote environment on local site instead of transmitting force/velocity flows. Thus, the user perceives locally(More)
— The concept of a mobile haptic interface for bimanual manipulations in 6 d.o.f. is presented. The design of this mobile haptic interface is based on a modular system consisting of two components: two haptic interfaces and a mobile platform. This work mainly addresses the design and control concepts of the haptic interfaces, which are planned to be mounted(More)
