In Carnegie Mellon University’s CyberScout project, we are developing mobile robotic technologies that will extend the sphere of awareness and mobility of small military units while exploring issues of command and control, task decomposition, multi-agent collaboration, efficient perception algorithms, and sensor fusion. This paper describes our work on robotic all-terrain vehicles (ATVs), one of several platforms within CyberScout. We have retrofitted two Polaris ATVs as mobile robotic surveillance and reconnaissance platforms. We describe the computing, sensing, and actuation infrastructure of these platforms, their current capabilities, and future research and applications.
