Virtual Reality Based Multi-Modal Teleoperation Using Mixed Autonomy, Muthukkumar S. Kadavasal, Abhishek Seth, James H. Oliver Aug 2008

Virtual Reality Based Multi-Modal Teleoperation Using Mixed Autonomy, Muthukkumar S. Kadavasal, Abhishek Seth, James H. Oliver

Mechanical Engineering Conference Presentations, Papers, and Proceedings

A multi modal teleoperation interface is introduced featuring an integrated virtual reality based simulation augmented by sensors and image processing capabilities on-board the remotely operated vehicle. The proposed virtual reality interface fuses an existing VR model with live video feed and prediction states, thereby creating a multi modal control interface. Virtual reality addresses the typical limitations of video-based teleoperation caused by signal lag and limited field of view thereby allowing the operator to navigate in a continuous fashion. The vehicle incorporates an on-board computer and a stereo vision system to facilitate obstacle detection. A vehicle adaptation system with a priori ...


A General Architecture For Distributed Vr Interfaces, Thomas Batkiewicz, Abhishek Seth, Bryan Walter, Jared Knutzon, James H. Oliver Aug 2008

A General Architecture For Distributed Vr Interfaces, Thomas Batkiewicz, Abhishek Seth, Bryan Walter, Jared Knutzon, James H. Oliver

Mechanical Engineering Conference Presentations, Papers, and Proceedings

This paper describes a software architecture useful in creating new virtual reality interfaces across a clustered network of computers. The architecture takes advantage of a concept common to desktop application development, the event loop, and provides a method by which it can be shared effectively between nodes in a cluster. This method improves upon the common replication approach to cluster synchronization by creating a single, simple object to share, as well as by supporting node specialization in a generic cluster. The method is designed to be easily added to existing applications as well as speed the development of virtual reality ...
