We’ve been making slow, intermittent progress on firmware for the Brushbot.  We reached a new milestone in November, however.  We now have simultaneous IR code transmission and reception working, both between bots as well as within a single bot to use for obstacle detection.

Cat uploaded a video she took of my dual brushbot avoiding / attacking objects, during the November 15 group project meeting.  See the PARTS flickr pool.

We had a great time at the November meeting watching and discussing a number of different robot-related videos.

Here are links to most of them:

Scott Dixon will fill in details of how to use it.  Enjoy!

Announcement: the rules for the new PARTS Indoor Challenge are posted. Get your robots ready for the April 3rd Meeting!

After the main meeting, the group build of the BrushBot controller will take place.  Those not participating in that may want to go watch the rest of the Autodesk Oregon Regional FIRST competition at the Memorial Coliseum.

Owing to the lack of meeting space (TechShop closed, bRainSilo being renovated) as well as the fact that Monty won’t be ready for us to do a group build of the BrushBot PCB, we’re going to cancel today’s meeting.

Instead, this would be a great time for people to contribute to the Wiki and start writing code for the BrushBot.

If you are active in the group project, please sign up for an account at http://colab.portlandrobotics.org. We’ve been tweaking the permissions for new users, so hopefully you will be able to edit and contribute to existing group project pages. If you have trouble, please contact me.

I’m starting a summary of experiments we’ve done with the $2 brushbots.  Please contribute here.

Looks like Monty got two versions of the simple brushbot controller ordered through the Dorkbot PCB fab group order.  Can’t wait to try them!

Be sure to check out the group projects pages as well as the list of topics for chalk talks.  If you join this site, you’ll be able to contribute to this site.
