US OPEN!!!

Hello everybody! So sorry for the lack of blogging. The US Open page is now up and running just in time for the competition.

In the US Open 2012 tab (up right), scroll down to the very bottom of the page. You will find a link to the live stream and the schedule. We will try to keep the scores updated there and in our posts as well.

Hope you can join us at Watson Arena or on the webcast!

Why are we so slow?…. Oh yeah…

So when we finally got a working robot back from Aldebaran’s Nao Clinic, we put it on the field and set it off walking. To our horror it immediately started shaking as it walked. At first we were very confused; some were thinking, “What have we done to our code?” Others were convinced, “Aldebaran did it!”  But after some quick timing of our processes, we found that the DCM was taking an unusual amount of time, 35 milliseconds to be exact. And that’s very significant if we want to be running at 33 milliseconds per image we get from our camera. The DCM essentially lets us control the robot’s body. It turns out that because of the DCM, we were instead running at around 75 milliseconds per frame. After some digging in the code, Jack found a few commands that told the DCM to wait for some number of milliseconds. And it happened to be 5, 10, 20 (5 + 10 + 20 = 35) hmmmm…. Thanks Joho…. On the plus side, we’re pretty sure we are the only team here that has doubled their frame rate in 15 minutes. Good start we think.

Home Sweet Istanbul!

 

We made it! All together and in one piece. Here’s a selection of photos from our first night before we hit the code running and only see daylight scarcely. Happy 4th to everyone back home!
