Wednesday 29th March 2006 - Alexandre

Agenda

  1. Presentation / Discussion
    • The presentation is about the results of my experiments on negotiation of direction for cooperative transport.
    • I'll explain the experiments, present and discuss the results, and also ask your opinion about future work.
    • The (say) ten last minutes I'll present you the next work I plan to do.

Open document presentation (openoffice2) available : http://iridia.ulb.ac.be/~acampo/various/nego021.odp The same as a pdf : http://iridia.ulb.ac.be/~acampo/various/nego021.pdf

Wednesday 1st March - Shervin

Agenda

  1. Presentation / Discussion
  • Shervin would like to rehearse the talk he will give next week at the IAS-9 conference. The talk is very similar to the one given in October, so for those who already followed it by then it might be quite boring to hear the same stuff again....

Wednesday 1st Febuary - Elio

Agenda

  1. Presentation / Discussion

This week I am going to give a "VERY INFORMAL" (please note the "informal") presentation on some work I'm currently doing on the evolution of signaling using Evolutionary Robotics methods. Note that, the meeting will be strictly focused on the description of my experiments (which, unfortunately for me, they are not very successful at the moment). So, if you are not interested in listening my sorrowful talk, you can certainly miss it.

Wednesday 11th January - Alexandre

Agenda

  1. Presentation / Discussion
  • I will introduce a new experiment that involves a group of robots trying to estimate collectively

the direction of the nest, whereas they can not see it anymore.

  • After a quick description of the experiment I'll introduce a set of simple behavioural rules devised to produce the desired collective behaviour.
  • Then I'll present some simulation results, and describe how the group of robots manages to estimate the direction

of the nest, and how it behaves in varying conditions (noise of the system, number of robots, duration of the experiment...).

  • Lastly I will discuss some tradeoff problems : robots estimate better the direction

of the nest if they are numerous, but on the other hand they have difficulties to synchronize for achieving a collective prey retrieval.

  • And I will discuss some scalability and bifurcation features of the system
  • If I have some time, but it is not likely, I will present you my latest results on optimal foraging

and improvements I did, following the suggestions of many of you.

  • Anders: Robotics room server
    • There is a new computer in the arena. It needs to be installed and configured. For people who do not have laptops and for the overhead camera, etc.
  • Anders: s-bot status (Rehan is going to kidnap the robots?)
    • Rehan is (maybe) going to take all the s-bots to Switzerland the final week of January.
  • Anders: BibTeX file for robotics conferences and journals.
    • A common BibTeX DB is already on the way. In a months time we should be able to test it.
  • Marco: Who takes care of the e-pucks?.
    • The e-pucks will arrive soon. Noone volunteered to test them. Marco will pick one at random.
  • Marco: NASA wants to cooperate with us.
    • IRIDIA is likely going to sign a contract with NASA for a number of experiments, in simulation and on the real robots, for transporting (lifting) building material on the moon.

Wednesday 23rd November - Christos

Agenda

  1. Presentation / Discussion
    • Communication - some brief overview, some definitions (this was supposed to have been discussed some months ago when nobody showed up to discuss a related paper I proposed, I guess this time with some "pressure" you will all be there and super-motivated and interested, what a wonderful world...
    • I am going to talk on my work on the Evolution of Communication in cases where there is no fitness reward for signalling-reaction to the signal. What conditions seem to favour the evolution of communication?
    • An idea for extention, an intro for my next talk, maybe?

  • Coffee machine: Various options available. Ciro is taking care of calling the people in charge of the ULB expresso machine deal.
  • New wiki pages:
  • Career developement plans online: Alex is going to propose a technology for the next meeting, which allows us to have up-to-date career development plans online, but only accessible by the student in question and his/her supervisor.
  • Arena camera: Federico is going to look into camera software and hardware for next weeks meeting (for the arena, since the movies shot with the current camera are of poor quality.
  • OMiss with 2D dynamics: We all believe that having the OMiss work with a 2D dynamics engine as well as ODE would be a good idea for many experiments. It might take too much time to implement though and no one seemed too keen on actually implementing it. We will see at the next meeting.


Wednesday 26th October - Anders

Presentation / Discussion Topics

Dependability and fault-tolerance in Robotics:

  • What is fault-tolerance and dependability?
  • What has been done in robotics?
  • How could fault tolerance be implemented in a swarm robotics context?

  • General: The topics on the agenda, which are of general interest are moved to the beginning of the meeting, so that non-robotics people can attend at a fixed hour each week.
  • Coffee machine:
    • Marco buys a new one when he comes across a good, new coffee machine (suggestions are very welcome)
    • Mauro is in charge of sending the current, broken machine to someone who can repair it.
  • New Wiki-pages:
  • Wiki security: For certain parts of the Wiki it would be convenient to have access control, so that only people from IRIDIA can access those pages. Anders will look into that.
  • E-pucks: All the available info on the e-pucks will be put on the Wiki.
  • Sbot/simulator interfaces: Rehan is going to create a repository for the common sbot interface and it is going to be implemented in TwoDee.
  • OMiss simulator: Rehan is going to create a Wiki page on checking out and compiling OMiss (the new simulator based on ODE).

  • The optimization group will have their own weekly presentations, but the will invite robotics people to participate, just like the swarm-bots presentations are open to optimization people. Seminars will continue as always and presentations might be given both at weekly meetings and at seminars.
  • Anders brings his coffee machine to test it. In case it pass the Italian test, we will buy one while the super-machine is being fixed.
  • Simulators and a standard interface for simulators:
    • Rehan and Alex are going to talk to Vito and make a plan
    • Rehan proposed Halva's interface, which he is going to send to Ciro and Anders for discussion on the next meeting
