Paper Abstract

Deploying robotic devices for Web-based teleoperation is currently the domain of academic researchers, commercial enterprises and a small group of dedicated hobbyists. Before more people can deploy their own devices, a number of difficult issues need to be addressed. In previous work, we presented a reusable framework for Web-based teleoperation of robotic devices and attempted to address some of these deployment issues. However, a number of problems still remain, including how to support communication with a mobile remote device. Any remotely operated device requires some form of communication channel to its operator. In many current systems, this communications channel is composed of a long-haul network connection as well as a short-range connection between the device and a base unit. For a mobile device, one traditional solution for this short-range connection has been tethered operation. Tethered operation imposes a number of undesirable limitations on mobile devices however, so many researchers have turned to wireless communication as an alternative. As both the monetary and power costs associated with wireless communications continue to decrease, it becomes more viable as a general solution to the problem of providing communication between a base unit and a mobile device. We present an overview of the current state of the art in commercially available wireless communications and its implications for Web-based teleoperations. We also discuss how the requirements and implementation of our existing reusable framework will be modi ed in response to the new requirements imposed by wireless communication.
