Mobile robot navigation using self-similar landmarks

Abstract: We propose a new system for vision-based mobile robot navigation in an unmodeled environment. Simple, unobtrusive artificial landmarks are used as navigation and localization aids. The landmark patterns are designed so that they can be reliably detected in real-time in images taken with the robot's camera over a wide range of viewing configurations. The code for the recognition algorithm is available in the web site.

Recent Advances in Synchronous-Clock One-Way-Travel-Time Acoustic Navigation

Abstract: This paper reports recent results in the development and deployment of a synchronous-clock acoustic navigation system suitable for the simultaneous navigation of multiple underwater vehicles. The goal of this work is to enable the task of navigating multiple autonomous underwater vehicles (AUVs) over length scales of (D(100 km), while maintaining error tolerances commensurate with conventional long-baseline transponder-based navigation systems (O(1 m)), but without the requisite need for deploying, calibrating, and recovering seafloor anchored acoustic transponders. Our navigation system is comprised of an acoustic modem-based communication/navigation system that allows for onboard navigational data to be broadcast as a data packet by a source node, and for all passively receiving nodes to be able to decode the data packet to obtain a one-way travel time pseudo-range measurement and ephemeris data. We present field results for a two-node configuration consisting of a surface ship acting as a global navigation aid to a Doppler-aided AUV

Design, implementation and evaluation of a novel public display for pedestrian navigation: the rotating compass

Abstract: Important drawbacks of map-based navigation applications for mobile phones are their small screen size and that users have to associate the information provided by the mobile phone with the real word. Therefore, we designed, implemented and evaluated the Rotating Compass - a novel public display for pedestrian navigation. Here, a floor display continuously shows different directions (in a clockwise order) and the mobile phone informs the user when their desired direction is indicated. To inform the user, the mobile phone vibrates in synchronization with the indicated direction. We report an outdoor study that compares a conventional paper map, a navigation application running on a mobile device, navigation information provided by a public display, and the Rotating Compass. The results provide clear evidence of the advantages of the new interaction technique when considering task completion time, context switches, disorientation events, usability satisfaction, workload and multi-user support.

Mobile robot mapping in populated environments

Abstract: The problem of learning maps with mobile robots has received considerable attention over the past years Most of the approaches, however, assume that the environment is static during the data-acqui

Healthcare tele-robotic system with a robot that also functions as a remote station

Abstract: A robotic system that includes a plurality of robots that are linked to a plurality of remote stations. The robots have an input device and software that allows control of another robot. This allows an operator in close physical proximity to a robot to operate another robot. Each robot can be either a master or slave device.
