Exploration and Mapping in Visually-degraded Environments using Aerial Robots - Preliminary Results 

11/21/2016

0 Comments

 
​These are preliminary results on exploration and mapping inside a tunnel with approximate dimensions of WIDTHxHEIGHTxLENGTH = 3x4x30m. The robot navigated along half of it (approximately) and our team evaluated the capability of localization and mapping using NIR camera/IMU, as well as Laser Time-of-Flight sensors. 

For the element of VI-localization we are using ROVIO developed at ASL, ETH Zurich: https://github.com/ethz-asl/rovio 

The nightvision cameras are supported with appropriately synchronized LEDs.

This result corresponds to preliminary work in the field of autonomous exploration and mapping in visually-degraded environments.

Autonomous Robots Lab gives a demo to NSTec from the Nevada Nuclear National Security Site

11/1/2016

0 Comments

 
Our lab had a day-long meeting with NSTec from the Nevada National Security Site and gave a demo of Autonomous Exploration and Mapping in Unknown GPS-denied environments. The goal is to develop advanced robotic systems capable of addressing the challenging needs of nuclear monitoring in terms of multi-modal data, visually-degraded environments, robustness and safety.

    I try to post basic updates here! Before August 2015, all posts appear to have happened the same day. This is due to moving my website.
