Robots: Curved Artificial Compound Eye

In this episode, we speak with Ramon Pericet and Michal Dobrzynski from EPFL about their Curved Artificial Compound Eye (CurvACE) published in the Proceedings of the National Academy of Sciences. Inspired by the fly’s vision system, their sensor can enable a large range of applications that require motion detection using a small plug-and-play device. As shown in the video below, you could use these sensors to control small robots navigating an environment, even in the dark, or equip a small autonomous flying robot with limited payload. Other applications include home automation, surveillance, medical instruments, prosthetic devices, and smart clothing.


The artificial compound eye features a panoramic, hemispherical field of view with a resolution identical to that of the fruitfly in less than 1 mm thickness. Additionally, it can extract images 3 times faster than a fruitfly, and includes neuromorphic photoreceptors that allow motion perception in a wide range of environments from a sunny day to moon light. To build the sensors, the researchers align an array of microlenses, an array of photodetectors, and a flexible PCB that mechanically supports and electrically connects the ensemble.

This work is part of the European Project Curvace which brings together a total of 15 people from four partners in France, Germany and Switzerland.

Robots: Senseable Robots

In today’s episode we look at some of the work done by the Senseable City Lab. We’ll be talking to Carlo Ratti, the director of the Lab, about two of the Lab’s many projects – namely Flyfire and Seaswarm.

Carlo Ratti

An architect and engineer by training, Carlo Ratti practices in Italy and teaches at the Massachusetts Institute of Technology, where he directs the Senseable City Lab. He graduated from the Politecnico di Torino and the École Nationale des Ponts et Chaussées in Paris, and later earned his MPhil and PhD at the University of Cambridge, UK.

As well as being a regular contributor to the architecture magazine Domus and the Italian newspaper Il Sole 24 Ore, Carlo has written for the BBC, La Stampa, Scientific American and The New York Times. His work has been exhibited worldwide at venues such as the Venice Biennale, the Design Museum Barcelona, the Science Museum in London, GAFTA in San Francisco and The Museum of Modern Art in New York. His Digital Water Pavilion at the 2008 World Expo was hailed by Time Magazine as one of the ‘Best Inventions of the Year’. Carlo was recently a presenter at TED 2011 and is serving as a member of the World Economic Forum Global Agenda Council for Urban Management. He is also a program director at the Strelka Institute for Media, Architecture and Design in Moscow and a curator of the 2012 BMW Guggenheim Pavilion in Berlin.

Carlo founded the Senseable City Lab in 2004 within the City Design and Development group at the Department of Urban Studies and Planning, in collaboration with the MIT Media Lab. The Lab’s mission is to creatively intervene and investigate the interface between people, technologies and the city. Whilst fostering interdisciplinary, the Lab’s work draws on diverse fields such as urban planning, architecture, design, engineering, computer science, natural sciences and economics to capture the full nature of urban problems and deliver research and applications that empower citizens to make choices that result in a more liveable urban condition.

Robots: Odor Source Localization

In this episode we revisit robot olfaction and take a closer look at the problem of odor source localization. Our first guest, Hiroshi Ishida from the Tokyo University of Agriculture and Technology is an expert in the field, whose sniffing robots range from blimps to ground and underwater robots. Our second guest, Thomas Lochmatter from EPFL talks about tradeoffs between biologically inspired and probabilistic approaches to navigate a gas plume.

Hiroshi Ishida

Hiroshi Ishida is Associate Professor in the Department of Mechanical Systems Engineering, Tokyo University of Agriculture and Technology, Japan.
The focus of his research group is to develop robots that can find sources of airborne gas plumes or underwater chemical plumes. To this end, they developed the Active Stereo Nose (see figure below), a differential gas sampling system inspired by the dog’s nose, and the Crayfish robot that mimics the mechanism used by crayfish in nature to create unidirectional water currents.

During his PhD at the Distributed Intelligent Systems and Algorithms Lab at EPFL in Switzerland, Thomas Lochmatter developed a modular odor system for the Khepera III robot. His research focused on the pros and cons of biologically-inspired and probabilistic algorithms for odor localization, while dealing with both single and multi-robot systems.

Robots: Autonomous Vehicles

In today’s episode we take a deeper look at what’s behind the hype over autonomous vehicles, and talk to two experts in the field, Alberto Broggi, leader of the Vislab Intercontinental Vehicle Challenge, and Raul Rojas, leader of the Made in Germany autonomous vehicle project.

Alberto Broggi

Alberto BroggiAlberto Broggi is the Director of the Artificial Vision and Intelligent Systems Lab at the University of Parma.

His main milestones are the ARGO Project (a 2000+ km test done on Italian highways back in 1998 in which the ARGO vehicle drove itself autonomously) and the setup of the Terramax vehicle who reached the finish line of the DARPA Grand Challenge 2005. The Vislab Intercontinental Vehicle Challenge was accomplished when the vehicle expedition recently reached Shanghai on October 28th after crossing two continents in a journey more than 3 months long.

Raúl Rojas

Raúl Rojas is a professor of Computer Science and Mathematics at the Free University of Berlin and a renowned specialist in artificial neural networks.

The FU-Fighters, football-playing robots he helped build, were world champions in 2004 and 2005. He formerly lead an autonomous car project called Spirit of Berlin and is now leading the development of the Made in Germany car, a spin-off project of the AutoNOMOS Project. Although most of his current research and teaching revolves around artificial intelligence and its applications, he holds academic degrees in mathematics and economics.

Robots: Olfaction

In this episode we look at how robots can use smell to navigate and map their environment or detect hazards. Our first guest, Achim Lilienthal from Örebro University in Sweden focuses on mapping gas clouds and localizing their source. Our second guest, Lino Forte Marques from the University of Coimbra in Portugal tells us about applications and sensors.

Achim Lilienthal

Achim Lilienthal is Associate Professor at the AASS Research Centre, Dept. of Technology, Örebro University in Sweden where he leads the Learning Systems Lab.

One of his main research goals is to use mobile robots equipped with gas sensors to map chemical clouds or localize their source. This requires making models of how gas diffuses in different environments based on many factors including wind. More unexpected however, is the use of smell for localization. For this purpose, Lilienthal who is also an expert in Self-Localization and Mapping techniques (SLAM) suggests that robots could figure out where they are by recognizing an odor previously encountered… say the smell of bacon frying in the kitchen. Finally, he discusses differences in natural and artificial smell and possibilities for 3D gas mapping.

Lino Forte Marques

Lino Forte Marques is an Assistant Professor in the Electrical Engineering Department of the University of Coimbra, Portugal, and Head of Research of the Embedded Systems Lab within the Institute of Systems and Robotics.

His research group wants to use teams of smell-endowed robots to research techniques that could be used for real-world applications like humanitarian demining, search and rescue operations, detecting fire hazards and counter-terrorism.
In order to achieve this, they have developed a cheap, small and modular odor sensing system called the kheNose for the popular Khepera III robot. An attractive feature of this system is that it is capable of odor discrimination, an ability often overlooked with other research modules that focus on detecting one particular substance in an otherwise odor clean environment. This makes it more suitable for realistic scenarios for which a clean environment is not necessarily a given.
