DPRG mailing list archives: [DPRG] field robot competition

Sun Jul 1 12:57:52 CDT 2007

Even while the team has nice success, this site again demonstrates that
operational environments is very much a relative thing.

In the June 2006 section of this page
http://www.fieldrobot.wur.nl/robot1/index.htm outdoor temperatures above 30C
is identified as 'extreme.'

It isn't uncommon for my work area to hit 28C before I start thinking about
closing windows.  The DPRG RBNO site probably exceeds 30C in the test area
on a regular basis.

Some of the photos on these sites capture bright sunny days but I wonder how
far out of operational spec the robots would be if placed under intense sun
in a cotton field in Lubbock.

One of our clients has us installing a mobile computing solution for crews
that work outdoors and that will see time in hot summers and mountain
winters.  We are trying to stick with COTS gear and supporting -30C to 60C
is practical but doesn't quite cover the expected range.  Even with these
parameters we've had no luck finding a Bluetooth radio in SD or CF form
factor that supports operating temps below -25C.    Any leads would be much
appreciated.

Howdy,

Dr Frits K. van Evert and his students at the Wageningen University and
Research Center in the Netherlands have built a two-wheel balancing
robot to compete in the "field robot competitions."  He sends along
a link to their robot navigating autonomously along rows of corn:

<http://www.fieldrobot.wur.nl/robot2/index.htm>

as well as a link to the field robot competition itself:

<http://www.fieldrobot.com/>

Looks like the navigation is accomplished with vision processing.  In
one link we have a two-wheel balancing robot, vision processing, and
an outdoor real-world robot contest.  A great job by our brother (and
sister) robot builders in the Netherlands.

best,
