"Could I bother you for a BOM ? I am very interested in mapping large areas outside in fields. This looks like the application that would fit my need. Thank you"

"Dear Ed. Although we are currently not working on a commercial product, I can tell you that all the components here are low-cost. They are cameras, LEDs, IMUs, embedded electronics (custom-built) and the only thing that increases the price is the…"

Autonomous Exploration inside Dark Tunnels

Posted on October 26, 2017 at 7:30pm 8 Comments

Dear community,



In these two videos you will see some recent results on autonomous exploration of tunnels in visually-degraded (dark) conditions. Both localization and mapping, as well as path planning and control are handled completely autonomously. …

Open-source: Localization Uncertainty-aware Exploration and Mapping Planner

Posted on June 2, 2017 at 1:30am 4 Comments

Dear community members,

During this ICRA we presented our work on "Uncertainty-aware Receding Horizon Exploration and Mapping using Aerial Robots".

This work is now accompanied with an open sourced ROS toolbox available at:…

Robotized Radiation Mapping

Posted on April 25, 2017 at 6:26pm 0 Comments

Dear community members,

This is very preliminary work on aerial robotic radiation detection in real-time and in a GPS-denied manner. The robot localizes based on visual-inertial data and integrates a deferentially installed 2-radiation detectors solution to exploit their polarity characteristics. Most of the research is ahead but we…

Autonomous Exploration and Mapping in Darkness

Posted on March 7, 2017 at 2:00pm 3 Comments

We would like to share two of our recent and ongoing results related to autonomous exploration and mapping in darkness. As opposed to approaches that rely on localization based on LiDAR systems, the videos below rely on visual-inertial localization with LEDs illuminating the scene appropriately. For the first case, visible-spectrum cameras are…

Autonomous Exploration and Inspection Using Flying Robots

Posted on January 28, 2016 at 10:53pm 11 Comments

Hi all, 

We recently released this video on autonomous exploration and inspection. Have a look!

Summary: 

The robot employs its visual-inertial navigation system in order to localize itself in the environment and simultaneously map it and 3D reconstruct it. Based on the newly proposed "Receding Horizon Next-Best-View…
