2 NXT's collaborating to move 3 objects from a grid

We now have a working multi-agent system. The video below shows 2 NXT's removing their respective objects from them lego grid. The video is low quality due the fact that it's hosted at google video. A high res version is available here (25,0 MB).



Our updated problem is now defined as follows:

Two teams, black and silver, of modified tribot agents are collaborating to move a number of black and silver items in a closed world back to their individual home bases (their initial postions). Only silver team tribots can remove silver items, and the black items can only be removed by the black team. If a tribot encounters an item which it is not able to remove, it must communicate the finding to the other tribots.

For all danes who did not get to read the twopage special on our project in Ingeniøren (The Engineer), here is a link to the online version with pictures.

Single agent identifying and retrieving objects

We have made a lot of progress since the last post. We have a fully functional implementation of the A*-path planning algorithm, which has been implemented in our C# agent. Also we have made a new grid with genuine lego plates, where we have put some black tape and pieces of reflective foil to make the actual grid, which allows the NXT to navigate.

We currently have a working solution that enables one NXT controlled by an agent on the .NET platform to identify and retrieve objects of a desired color. We shot a video of a run:



At the moment we are working on putting more players in the game. Hopefully we will have a working solution on wednesday.
