Our goal is to make vehicle teleoperation accessible to all users. To do this, we are developing easy-to-use yet capable Web tools which enable efficient, robust teleoperation in unknown and unstructured environments. Webbased teleoperation, however, raises many research issues, as well as prohibiting the use of traditional approaches. Thus, it is essential to develop new methods which minimize bandwidth usage, which provide sensor fusion displays, and which optimize human-computer interaction. We believe that existing systems do not adequately address these issues and have severely limited capability and performance as a result. In this paper, we present a system design for safe and reliable Web-based vehicle teleoperation, describe an active and dynamic user interface, and explain how our approach differs from existing systems.
