Narrated guided tour following and interpretation by an autonomous wheelchair
… concerned with is a speech-commandable robotic wheelchair operating in a home/special care environment, capable of navigating autonomously to a verbally-specified location in the environment. We address this problem by incorporating a narrated guided tour following capability into the autonomous …

Detection of dynamic obstacles out of the line of sight for autonomous vehicles to increase safety based on shadows
… in mobile robotics applications such as autonomous vehicles. In this work, we address the problem of anticipating such potential collisions by proposing a vision-based detection algorithm for obstacles which are outside of a vehicle's direct line of sight. Our method detects shadows of …

Novel techniques for improved indoor positioning and localization using HF RFID
… antenna to localise moving objects such as autonomous wheelchairs in indoor environments. Typical HF RFIDs operate at 13.56 MHz and employ passive tags which are excited by the magnetic field radiated by the reader antenna. Positioning of moving objects using HF RFID systems derive location …
