Meeting of October 23rd 2008

Attendees: Tim Bertholet, Maurice van den Heuvel, Hans Odenthal, Dorieke Schipper, Grayson Penzo and Erik Vermeulen

New project members!

Last year, we started our project with 10 members. Since then, Jeroen, Kees-Jan, Erwin, Peter and Maurice Beelen have left the project due to several reasons, mostly lack of time.
Today, Dorieke and Grayson were present to see what our project is all about and they may be joining us. First we introduced our project by doing a quick walk through through some presentations and this blog.
After that we proceeded with our meeting as if it was a regular one.

What has been done last month?

Erik created a new nk.bin image that includes the Via VT6655 Mini-PCI Wi-Fi driver. The running image also supports a persistent file system and registry (like Tim's image) so files and registry settings survive a reboot. This is also true for the WLAN passwords. From now on, entering your WPA2 key once will do.
On the eBox’ desktop I’ve also put a new link “Listen for Visual Studio” that starts both the conmanclient.exe and cmaccept.exe in order to support remote debugging from Visual Studio. By the way, I replaced them with the ones needed for Visual Studio 2008.
Furthermore I changed the eventing demo so it works with an actual Roomba. However, during my demo the demo effect kicked in: an exhausted battery screwed up my demo :(. Better luck next time.

Maurice integrated his TCP/IP implementation into the Siimon solution. He noticed that some methods are missing on the interfaces. These will be added and implemented by Tim and Erik soon. They will meet regularly the following weeks to get this done. Our goal is to have the bottom layers implemented asap so we can start with the more challenging parts: adding some form of ‘intelligence’. Basically this bottom layer implementation is similar to the RoombaSCI library; however it will have high level events added to it (OnBumperPressed, VoltageChanged etc.).

While discussing the project we concluded that for the intelligent part, we may need more sensors. Currently there is no good way to determine the robot’s position. The following weeks we will all have a look at auxiliary sensors.

Our next meeting will be on Thursday, December the 4th 2008, starting at 17.45. See you then!
