John Folkesson



I am an Associate Professor and Docent at  the department of Robots Perception and Learning, at the Royal Institute of Technology, and the School of Computer Science and Communications.  I was formerly a research scientist at the Massachusetts Institute of Technology , Department of Ocean Engineering.

My research is concentrated on  data fusion and world modeling for mobile robotics,  particularly for navigation.   The idea is to make machines that can learn how to find their way around without the need for guidance. 

To do this the robot needs to form models of the environment suitable to the task.  That might be simply avoiding obstacles or, more complicated tasks like finding its way back to a location previously visited.   These models need to be learned and refined based on the observations made by the robot.  It is this learning that I am focused on

Current Projects:

SSF Swedish Maritime Research Center SMARC: I am one of the participants. The project is lead by KTH and has partners SAAB Dynamic, SAAB Kockoms, MMT, University of Gothenburg and Stockholm University. We will advance underwater autonomy in Blue Growth industries, Environmental monitoring, and security.

EU Integrated Project CENTAURO: I am one of the participants of the consortium of 6 universities. The project is development of a unique rescue robot.

VINNOVA Project IQPilot: I am a participant along Scania, Ericsson, and Autoliv. The goal is autonomous driving of city busses.

Past Projects:

EU Integrated Project STRANDS: A consortium of 6 universities and two industrial partners. We worked on the problem of long term learning by robots in real world settings.

VINNOVA Project IQMatic: A consortium of KTH, Linköping University, Scania, SAAB, and Autoliv. The goal was autonomous driving of tracktor trailer trucks.

My   CV and   publications

My background includes graduate studies in Physics at the State University of New York at Stonybrook,  some work as a researcher at an electronics company in San Jose CA,  and  my own consulting business were I did statistical data analysis.

I have a Bachelor Degree in physics from the City University of New York.   And a  Masters in Computer Science from the Royal Institute of Technology in Sweden .  My  masters thesis  was entitiled Projection of a  Markov Process with Neural Networks.

I defended  Doctorial thesis on October 4, 2005.  Here is what the final version looks like  PhD thesis .

I have designed and implemented  a system for our outdoor robot, Pluto.  You can read about that here  pluto.pdf .    Pluto can  localize to a map to and goto a designated coordinate avoiding obstacles along the way.  Pluto can automatically explore and map an area using a laser range scanner to located the walls of buildings.   The robot can also investigate a parked car: approach it, extend its arm to position a camera to see under the car and then circle the car holding the camera always at the proper angle. 

Others in the lab have integrated with my system to add road  following, person following and simple arm movements.   A number of nice user interfaces have also been developed.  The work goes on but I am no longer directly involved. 

I also helped develope CURE (CAS Unified Robot Environment).  CURE  is a collection of libraries in C++ to help people working in the lab. 

I have also worked on underwater SLAM.

Also:  I play piano and have a patent for a music keyboard related invention.
