We are getting ready to order some gear motors and wheels for
the HBRC 2013 Club Bot class. As I mentioned at the HBRC meeting
on Wednesday, we are going to allow people who wish to tag along
with the order to do so. If you are in the class, your robot kit
fee already includes the needed motors and wheels. This offer is
I ran into the Open Hardware Mobile Manipulator project from Northeastern
It looks like an interesting project. Has anyone else seen this? Thoughts?
I think I might have left a battery charger at the Haker Dojo (this months SIG)...
That was over a week ago so it might be gone forever. There is still hope though, maybe someone has it.
Are there some calibration parameters that need to be tweaked?
There was quite a bit of stuff left behind at tonight's meeting.
There was a nice jacket, a "milk crate" with some electronics
in it, some weird video phone like things, etc. All of this
stuff has been transferred to Google security Lost + Found.
(Alas, I have misplaced the address...)
(Collectively, we totally dropped the ball on getting the
HBRobotics.Org web site updated for tonight's meeting.
We'll do better next time.)
Tonight's meeting is at 7pm. I am 98% sure that it is at
the Google Crusher Meeting room. I'll send out a follow
up message when I get final confirmation.
again! and there will be robots roaming around, speakers and maybe even
robot themed cocktails.
The event runs from 6pm -10pm. I'm hoping that someone will coordinate a
Homebrew group (you may already be going!) but I'm also collecting sign ups
to an email on an existing post and change the subject. Instead, start a
new email or start a new topic using the Web interface to the group,
located here: [link]. If you
reply to an existing email, your message will be combined with previous
bad. I'll tape it to watch one day when I'm bored and want to veg out.
Did you use the "extra" USB headers on the front of the mini-ITX? I had
a conflict when I tried them (might not have done it right).
I was looking a your "Head Tracking using OpenCV" blog, and I remembered
that you said something like the ros_arduino_bridge package is being
used on the new PI Robot. Did I get that right?
I had just installed the pi_head_tracking_tutorial (electric) on my
(diamonback, oops?). And thought I'd look for a closer match to using
You are now published:
The Neato Robot and ROS
making home-made X-Ray machines, and the danger involved.
Anyway, I noticed that someone posted a great Intructable on it...and
the dangers are well documented too.
I can run my Kinnects (turtlebot bringup or just the openni launch) and get images from the camera with the ros and rviz, but it gives me warnings on the point cloud data - saying no topic found
I can use the image command and get the depth data though, and I get rgb camera data displayed in rviz - the main display stays black. Once upon I time back in diamondback I did see data here.

The link for the git package on the ros_arduino_bridge wiki didn't work
(electric), however I did copy and "git" it from my ros_workspace.
I was also able to make it (under turtlebot, diamond? electric??) with
So not sure what I've got yet, and I haven't programmed the Arduino yet.
I'm building a 'bot for Robogames (San Mateo) Robomagellan. I've
FINALLY made a little progress with cmvision on ROS Electric.
