This paper studies the transparency of client/server-based haptic interaction with simulated deformable objects. In the considered remote interaction scenario, the server simulates the computationally expensive finite-element-based object deformation at a low temporal update rate and transmits the result to the clients. There, the received deformation data is applied to the polygon mesh, which is...
Bilateral teleoperation systems with haptic feedback allow human users to interact with objects or perform complex tasks in remote or inaccessible environments. Communication delays in teleoperation systems jeopardize system stability and transparency, leading to degraded system performance and poor user experience. In this paper, we provide a survey of the model-mediated teleoperation (MMT) approach,...
In this paper we describe a client-server architecture for haptic interaction with simulated deformable objects. The computationally expensive object deformation is computed on the server at a low temporal update rate and transmitted to the clients. There, an intermediate representation of the deformable object is used to locally render haptic force feedback displayed to the user at the required rate...
We propose a perceptual haptic data reduction approach for teleoperation systems which use the time domain passivity approach (TDPA) as their control architecture for dealing with time-varying communication delay. Our goal is to reduce the packet rate over the communication network while preserving system stability in the presence of time-varying and unknown delays. Compared to the existing wave variable-based...
