As part of Brickworld 2007 in Chicago, Jun 21-24, we are going to try to run at least four seperate Mindstorms events: *The ever-popular Sumo (4' ring, 2 lb limit, flipping strongly encouraged) *Line maze (find your way to the exit, as fast as (...)

Brickworld 2007, June 21-24, Chicago Gladiator Sumo: The competition will involve two robots in a circular ring, with the goal being to push your opponent out of the ring or otherwise disabling them within the time limit.

Re: Brickworld 2007 - Line Maze —Brian Davis

(...) Correct. (...) No, that was not the intent. That's why I said "every line segment and junction ALONG THE PATH from start to finish". Much of the maze will be line segments and junctions that are parts of dead-ends, not along the correct path. (...) (17 years ago, 19-Apr-07, to lugnet.events.brickworld, lugnet.robotics)

Re: Brickworld 2007 - Line Maze —Ralph Hempel

(...) Much clearer, thanks. The phrase "along the path" did not jump out at me the first time :-) Ralph (17 years ago, 19-Apr-07, to lugnet.events.brickworld, lugnet.robotics)

Brickworld 2007 - Rock Crawling —Brian Davis

Brickworld 2007, June 21-24, Chicago Rock Crawling: The goal is to accumulate points by conquering as many obstacles as possible along a “Rock Crawling” course, with the spirit being to produce a remote controlled vehicle that can traverse a very (...)

Brickworld 2007 - Indy 5.00 —Brian Davis

Brickworld 2007, June 21-24, Chicago Indy 5.00: Autonomous robots will run head-to-head races of five laps around a 8’x10’ oval gradient track. The event will be double-elimination or round-robin style (depending on the number of participants; (...) (17 years ago, 18-Apr-07, to lugnet.events.brickworld, lugnet.robotics)

Re: Brickworld 2007 - Indy 5.00 —Gus Jansson

(...) Okay, I'm confused. How can an 8' x 10' track be centered on a 4' by 8' surface? What is the actual width of the track? If the whole track fits on a 4' x 8' surface, then I would assume the width must be less then 2'. Gus (17 years ago, 17-Jun-07, to lugnet.events.brickworld, lugnet.robotics)

Re: Brickworld 2007 - Indy 5.00 —Bryan Bonahoom

(...) Seems clear to me :) there will be magic.... Actually - looks like a really wacky typo. Hopefully Steve H or Brian D jumps in to clarify for certain. But, I believe the full track layout is 4' x 8'. So, the track itself is just under 2' wide. (...) (17 years ago, 17-Jun-07, to lugnet.events.brickworld, lugnet.robotics)

Re: Brickworld 2007 - Indy 5.00 —Steve Hassenplug

(...) That appears to be a typo. The track fits on a FLL table, so it's a 44"x92" inch oval. And the lane is about 2ft wide. It's pretty easy to build and program a robot for this event. It just needs to follow a specific shade (actual value will (...) (17 years ago, 17-Jun-07, to lugnet.events.brickworld, lugnet.robotics)

Re: Brickworld 2007 - Indy 5.00 —Gus Jansson

(...) Thank you Steve, Brian, and Bryan for the clarification on the track size. One more question: Would it be possible for whoever currently has the track to post some approximate NXT light sensor readings for the various positions across the (...)

Re: Brickworld 2007 - Indy 5.00 —Bryan Bonahoom

(...) Gus, 1) Steve has the track...just got it a few days ago...I doubt he gets a chance to make any accurate/repeatable readings in the time available. 2) The track will be available to roll out on the floor (or wherever) all weekend long. Since (...) (17 years ago, 20-Jun-07, to lugnet.events.brickworld, lugnet.robotics)

Re: Brickworld 2007 - Indy 5.00 —Steve Hassenplug

(...) First, it's not a straight gradient. We wanted to make it with about three inches of black in the middle & the same in white on the outside. That gives the maximum range in the area where the robots will race. So, here are the numbers (nxt (...) (17 years ago, 20-Jun-07, to lugnet.events.brickworld, lugnet.robotics)

Re: Brickworld 2007 - Indy 5.00 —Johanâ˘Strandberg

(1) "the bumper should be at the height of the red Technic beam in this figure" Does this mean that a the design must use a studded beam? (A stud-less beam is not as "tall" as the beam in the image.) (2) "The bumper must be straight and not angled (...) (17 years ago, 17-Jun-07, to lugnet.robotics)

Re: Brickworld 2007 - Indy 5.00 —Brian Davis

[Sorry, I know this is a duplicate for some of you on the mailing list, but I wanted to answer this in LUGNET and hadn't realized before this is where the email came from. My bad.] (...) The bumper can be studded or studless, and could certainly (...) (17 years ago, 17-Jun-07, to lugnet.robotics)
