I have recently started as a senior researcher at the Autonomous Systems Lab at ETH Zurich. Previously I was a postdoctoral researcher at the PErceptual Robotics Laboratory (PeRL) and the Autonomy, Perception, Robotics, Interfaces, and Learning (APRIL) laboratory at the University of Michigan. My research interests are centered on decision-making under uncertainty and integrated perception, planning, and control for autonomous vehicles. At Michigan I worked on the Next Generation Vehicle (NGV) project with professors Ryan Eustice and Edwin Olson.

Research

Decision Making and Motion Planning At ETH Zurich's Autonomous Systems Lab I do research on perception and decision-making and motion planning for a variety of autonomous vehicles, with a focus on micro aerial vehicles (MAVs)—check out our YouTube channel. I am currently serving as vice-coordinator for the H2020 EU project FLOURISH, centered on ground and aerial robots collaboration for precision agriculture.

Autonomous Driving My research is currently mainly focused on the Next Generation Vehicle project, where I work on decision-making under uncertainty and integrated perception, planning, and control in the context of autonomous driving in real-world traffic scenarios. The project is a collaboration of the PeRL and APRIL laboratories at the University of Michigan, Ford Motor Company, and State Farm. We use a fleet of several autonomous vehicles equipped with INS, LIDAR and cameras, as shown in the video below. Visit the project's page to learn more.


Underwater Robotics During my time at the University of Girona, my work focused on underwater robotics. Currently I help out at PeRL with the PhD work of Ryan Eustice's students Jeff Walls and Stephen Chaves. Jeff's work involves path planning under uncertainty for cooperative localization of AUVs and Stephen's is focused on planning active SLAM for underwater visual inspection tasks.

My PhD work was centered on the problem of covering a surface of interest with a robot while avoiding obstacles, particularly in underwater scenarios. My thesis addressed 2D coverage, uncertainty-driven AUV survey planning, and autonomous inspection of 3D underwater environments using the GIRONA 500 AUV, equipped with optical imaging and sonar sensors. The automated inspection scheme proposed in the thesis goes beyond conventional AUV surveys which image the ocean floor from an overhead viewpoint. In contrast, we propose a 3D coverage path planning algorithm that enables the AUV to image the target structure from fair view points at different depths. This enables the AUV sensors to capture the full 3D information of the target structure. Beyond mere off-line planning, our algorithm adapts the inspection path in real time using sonar range information, dealing with the uncertainty present both in the low-resolution maps used to plan the path and in the AUV's localization system.

The video below demonstrates the method at sea in two different inspection tasks using the GIRONA 500 AUV. First, GIRONA 500 follows an automatically pre-planned path to inspect a concrete block on a breakwater structure at 5 m depth. Next, the AUV inspects a natural seamount ranging from 28 m down to 40 m depth. In both tasks the vehicle acquires bathymetry sonar and stereo camera data used to create 3D models and photomosaics of the inspected structures.


Visitor at Carnegie Mellon During 2012, I was for 6 months a visiting researcher at The Robotics Institute at Carnegie Mellon University in Pittsburgh, PA, in the US. As part of my PhD, I worked at the Biorobotics Lab hosted by Prof. Howie Choset.

Visitor at NURC (now CMRE) During 2011, I was for 3 months a visiting researcher at NATO's Undersea Research Centre (NURC), now called Centre for Maritime Research and Experimentation (CMRE) in La Spezia, Italy. There, I worked in target and obstacle detection using forward-looking imaging sonar under the supervision of Dr. Vladimir Djapic. Take a look at the slides of my NGCUV 2012 presentation for a summary of the work I carried on there.

Other Interests

I participated as core developer (2010) and team leader (2011) with the VICOROB-UdG team in the 2010 and 2011 editions of the Student Autonomous Underwater Challenge - Europe (SAUC-E). Our 2010 team built our torpedo-shaped robot Sparus from the ground up for the competition, and took again the challenge in 2011. We were the champions in 2010 and runner-ups in 2011.
