Revision as of 13:13, 3 June 2009
Purpose
- Community. Keep everyone updated as to what other work is going on in the lab
- Research. Cross germination. Get feedback. Get help on problems. Get ideas.
- Admin. Lab administration.
Format
- Presentation & Discussion (30 - 50 mins)
- Work you have been doing
- Reading you have been doing in the context of your work
- Other reading on something you are passionate about
- Swarmanoid internal meeting (0 - 50 mins)
Try and make your session as involving as possible for everyone:
- Send round material to be read beforehand.
- Ask people before the meeting what aspects of your work / reading they would like to know about or discuss.
- Think about implications of what you are presenting for the research direction of the lab as a whole - methodologies, technologies etc.
Timing & Attendance
The weekly meetings take place on
Unless:
- A given Wednesday is a public holiday, or
- Something very important (like a Ph.D. defense) is overlapping.
If either should happen the meeting is postponed to the next day.
Please indicate on this wiki page if you are not going to be able to attend a meeting (no later than the Friday before).
If you forget to note your absence in advance you will be severely punished and will be forced to buy a nice, big cake for the following meeting.

- Interference Reduction through Task Partitioning
The talk is about the use of task partitioning as a way to reduce interference in a spatially constrained harvesting task. Interference is one of the key problems in large cooperating groups. We present a simple method to allocate individuals of a robotic swarm to a partitioned task, and study how this task partition can increase system performance by reducing sources of interference. The method is experimentally studied, both in an environment with a constrained area and an environment without the constraint.

Agenda
- Presentation
- Phat-bot Assembly and Navigation
- The behavioral toolkit
- Internal Meeting / Discussion
- Swarmanoid Project: To be defined
Abstract: In this talk we will present the work we have been doing on the phat-bot assembly and navigation. All the controllers were implemented with a new architecture in mind, which made the modularity of the behaviors possible in ARGoS. We call this architecture "Behavioral Toolkit" and we will present it also during the talk.

- Local social influence mechanisms for collective decision making: A swarm robotics experiment
- Internal Meeting / Discussion
Abstract: In human societies, groups are often perceived as superior decision making entities than individuals. When an important decision has to be made, groups are formed to decide on the issue. Examples include referenda, elections, and juries. When individuals are part of a decision making group, they are subject to social influences that can affect their perception and/or their opinion on the issue. Our work is inspired by this fact and we investigate whether local social influence mechanisms can make a population of robots choose the best of two competing alternatives.
In our experiment, a swarm of robots is faced with a binary decision problem: go foraging to the left, or to the right; or push or pull a family of objects, for example. Associated to each choice there is a cost which is the time it takes for a group to perform the task. I will show you preliminary results that suggest that simple local decision rules can make an uninformed population (or even a negatively biased one) choose the best strategy (in terms of task completion time).

- A Reliable Distributed Algorithm for Group Size Estimation with Minimal Communication Requirements
- Internal Meeting / Discussion
- The ARGoS Constitution
Abstract: In this talk I will present a method that lets individual robots in a group estimate the size of the group in a distributed manner. The process is loosely based on the signaling behavior of fireflies and crickets. Melhuish et al. first devised a method based on local robot signaling to estimate the group's size. Each robot emits a signal and can perceive the signals of neighboring robots in close proximity. Following the approach of Melhuish et al., our robots count the number of emitted signals over a suitably defined period of time. Experiments show that the estimates calculated with Melhuish et al. method display a great deal of noise. We modify their method so as to sensibly stabilize the output. We assess the quality of our method through extensive simulation-based experiments.
