Probabilistic Indoor Positioning and Navigation (PIPN) of Autonomous Ground Vehicle (AGV) Based on Wireless Measurements

Vision-Based Autonomous Ground Vehicle Navigation

The Intelligent Ground Vehicle Competition (IGVC) is an international collegiate robotics competition that tasks each team to design, build, and program a fully autonomous mobile ground vehicle. Each successful entry must autonomously navigate through an outdoor obstacle course using only the sensors and computing power on-board the robot. As per the offical rules, the competition is split into...

Indoor Positioning and Pre-processing of RSS Measurements

Rapid expansions of new location-based services signify the need for finding accurate localization techniques for indoor environments. Among different techniques, RSS-based  schemes and in particular oneof its variants which is based on Graph-based Semi-Supervised Learning (G-SSL) are widely-used approaches The superiority of this scheme is that it has low setup/training cost and at the same ti...

Indoor Positioning Techniques Based on Wireless LAN

As well as delivering high speed internet, Wireless LAN (WLAN) can be used as an effective indoor positioning system. It is competitive in terms of both accuracy and cost compared to similar systems. To date, several signal strength based techniques have been proposed. Researchers at the University of New South Wales (UNSW) have developed several innovative implementations of WLAN positioning s...

Indoor Navigation Based on a Multimodal Positioning System

Daytime Mud Detection for Unmanned Ground Vehicle Autonomous Navigation

Detecting mud hazards is a significant challenge to UGV autonomous off-road navigation. A military UGV stuck in a mud body during a mission may need to be sacrificed or rescued, both unattractive options. JPL is currently developing a daytime mud detection capability under the RCTA program using UGV mounted sensors. To perform robust mud detection under all conditions, we expect multiple sensor...
