Dear David:
I have built something similar to LegWay. How I can get in touch with
Hassenplug,
do you have his mail address?

Oggetto: WS3D RCX Challenge #5 Results
> Yesterday was the Workshop 3D RCX Challenge #5. The Lego robotics
> competition took place in the Pacific Science Center in Seattle. Events • were
> line following (two divisions), sumo, and puck gathering. The code-only • line
> tracking event will be held at a later date.
>
> The first line following division was "Single RIS" - you can build a line
> tracking robot, using only the pieces from only a single Mindstorms • Robotic
> Invention System set? This means only a single light sensor may be used.
> Robots this time were run for 30 seconds on a looped track, and one which
> traveled furthest would win. A fair number of robots were entered here, • and
> Kyle Stone won! Congratulations, Kyle!
>
> The second division is "Unlimited", meaning any Lego pieces may be used,
> including multiple RCXs, and if desired, alternative sensors may be used • as
> well. Gus Jansson entered two robots in this division, one using
> rack-and-pinion steering, the other a more traditional design. • Interestingly
> they both robots reached exactly the same position on the track after • thirty
> seconds, but the traditional design had managed to squeeze in an extra • lap,
> and the win. Congratulations, Gus!
>
> Of interest in the unlimited line tracking competition were several
> non-traditional robot designs this year. Most robots used two motors, one
> for the left and one for the right wheel. Besides Gus' rack-and-pinion
> steering, there was also a 6-legged *walking* line tracker. There was a
> *one*-motor line tracker! And finally there was a line-tracker that • balanced
> on only two wheels! More on this one later.
>
> The second competition was Sumo. More robots were in this category than • any
> other, and the competition was fierce. The final winner, after a
> pseudo-double eliminiation tournament was Steve Hassenplug's robot "The
> Combine". Congratulations, Steve!
>
> The third competition was puck gathering. This time there were five robots
> in this event. Gus Jansson has won each year except last year, where • Barton
> Place stole the title from him. Well, after three rounds, with the total
> pucks collected in all rounds counting, Gus won the title back!
>
> A final event was exhibition robots. There were several entries for this.
> Gus Jansson displayed his helicopter, someone brought an interesting • walking
> robot, and Emmit Lalish won the event with a crane/claw combination robot
> that used only two motors but had perhaps five degrees of freedom. • Displayed
> at several key moments during the other events was a final entry by Steve
> Hassenplug who had a robot named LegWay, which balanced itself on two
> wheels. (Wonder where he came up with that name? :-) It could stand • (quite)
> still, spin in a very quick circle, and finally it could follow a line! An
> extremely impressive display of programming finesse, and a wonderful use • of
> a pair of EOPD sensors from John Barnes! I'm sure after seeing this robot,
> there will be many people interested in buying one or two of these!
>
> In any case, way to go, everyone that entered!
>
> I've put pictures of the event up on Brickshelf, at:
> http://www.brickshelf.com/cgi-bin/gallery.cgi?f=26849
> You might have to wait a day until they've been moderated before being • able
> to see them.
