Autonomous navigation with deadlock detection and avoidance
(Sociedad Iberoamericana de Inteligencia Artificial, 2014-02)
This paper studies alternatives to solve the problem of autonomous mobile robots navigation in unknown indoor environments. The navigation system uses fuzzy logic to combine the information obtained from range sensors and ...
Laser Radar Based Autonomous Mobile Robot Guidance System for Olive Groves Navigation
(Institute of Electrical and Electronics Engineers, 2015-05)
This paper proposes a control strategy for a mobile robot for precision agriculture. The controller allows autonomous navigation through corridors formed by plants or fruit vines and olive trees. Furthermore, a rotation ...
Exploring smart environments through human computation for enhancing blind navigation
(SpringerCham, 2015)
In this paper the orchestration of wearable sensors with human computation is explored to provide map metadata for blind navigation. Technological navigation aids for blind must provide accurate information about the ...
Mitigating systematic errors for single frequency GPS receivers employing a penalized least squares methodology
(2006-12-27)
Among the positioning systems that compose GNSS (Global Navigation Satellite System), GPS has the capability of providing low, medium and high precision positioning data. However, GPS observables may be subject to many ...

An optical flow-based sensing system for reactive mobile robot navigation
(2007-07)
This work discusses the use of optical flow to generate the sensorial information a mobile robot needs to react to the presence of obstacles when navigating in a non-structured environment. A sensing system based on optical ...
Fona: quantitative metric to measure focus navigation on rich internet applications
(ACMNew York, 2015-09)
The Web 2.0 brought new requirements to the architecture of web systems. Web applications’ interfaces are becoming more and more interactive. However, these changes are severely impacting how disabled users interact through ...
