[DPRG] Roborama 2012b Report

A HUGE Thank you to Jason for organizing a very enjoyable and successful
Roborama 2012b, and for enduring the headwinds that buffeted the event,
such as date changes, and for feeding the starving hords. About 20
people and 5 robots turned out for a warm, sunny day beside Lake
Lewisville. Jason brought meat for everyone, people brought sides &
desserts, and we enjoyed a cookout inbetween tuning robots and trying to
make them run the 400' racetrack course laid out across my and my
neighbor's back yard.


Patrick took first position by completing 3 turns of the course (about
2/3 of its length) using compass and odometry on a Lego/mindstorms robot
that he started programming when he arrived!!!!!! He showed his mastery
of simple and elegant solutions that work.


Paul and Jason took second with a vision-based mars-rover-style ROS
robot called JRover made of mostly Vex parts which they've been
programming since August. :-( JRover made it around one corner (about
1/3 of the course).


Please consider coming out and showing your robot at the First Lego
competition at Hockaday school on Saturday Jan 12. Note this is the 2nd
Saturday - normally the DPRG monthly meeting date - we'll reschedule the
meeting. Contact Paul for details.

I agree with you, Karim. I'm up for another crack this Spring or early
Spring (February?). 

In my post-mortem of my robot's run, I found some things that were easy
to fix. I itching

to do some more practice runs around my local park.


I also would not want to preempt Roborama2013a. I am hoping that we can
work out 

Roborama2013a's contests as early as possible. I hope to discuss it at
RBNO tomorrow. 


This Tuesday at RBNO, Richard and I are also planning to work through
installing an open 

source ARM tool chain as the first step for a new outdoor robot using
the STM32F3 discovery 

board. This board has an on-board IMU. If anyone is interested, they are
welcome to join us.

Hopefully someone will provide a better update.  There was also pretty
turn-out from on-looking DPRG membership.

I'm up for another crack at it in the spring.  I don't think it should
replace Roborama-A, but I also don't see why it couldn't run at the same
time as an exposition event.  There was nothing scary about those robots
moseying along - if anybody took video, it would be easy to demonstrate
park officials that this is something safe to do just about anywhere.
it would split-the-field between indoor and outdoor contestants and
Which was a bummer to many at the last Roborama-A.  So if folks don't
to sacrifice the opportunity to do both, separate contests are still an
option.  The outdoor contest could likely do with a few more informal
iterations before going public.

Just thinking out loud. Give more weight to what other say since they
actually put in the time to organize these things.  Much appreciation to
Jason and Paul and everybody else that helped pull it off.  The
was great.

This list has been awfully quiet for  a group with a contest just a few
days away!   I'm still not quite clear as to who is entering besides
Jason  (who is the contest designer after all,
wink-wink-nudge-nudge-say-no-more ;)

Anyway,  I'm home recovering from some surgery this week and
unfortunately won't be able to make it on Sunday.   If there is enough
interest to do another outdoor contest, later this spring or maybe next
fall, I hope to have jBot back up and running, and field an entry.

On that topic, I think Mike's Hobby outdoor off-road track would make a
great venue for a robot contest (90 and 180 degree turns, dirt and
lots of hills and valleys, no liability problems), and Mike is amenable,
tuck that away as a future possibility.

Best of luck to all participants and observers!

happy roboting,
