Please? </p> http://robocupjunior.org.nz/forum/topic/rescue-checkpoints#post-23 Wed, 28 Jul 2010 03:45:17 +0000 Lavinia Robyns 23@http://robocupjunior.org.nz/forum/ <p>We are using variables to program the sensors and using the logic block to inform the loop controller when both sensors read the green checkpoints. We want the robot to stop then turn. We can't get this to work - the stop and turn blocks are located outside the loop. What have we missed here? </p> http://robocupjunior.org.nz/forum/topic/best-robot-ever#post-2 Wed, 15 Jul 2009 00:05:41 +0000 admin 2@http://robocupjunior.org.nz/forum/ <p>If you had all the money in the world, what would you build? </p> http://robocupjunior.org.nz/forum/topic/nz-developed-rescue-tiles#post-10 Thu, 23 Jul 2009 00:37:18 +0000 davidt 10@http://robocupjunior.org.nz/forum/ <p>Fustrated at the time to order equipment from overseas I spent part of the last break 'perfecting' a NZ developed version of the resuce tiles in association with a local print/design company. These are individually cut tiles printed on to 6mm coreflute (the stuff estate agents signs are made from). Compared to what normally is on offer I think the following is a fair assessment of the outcomes.</p> <p>Advantages:-<br /> 1) Lightweight, full set just a couple of kg.</p> <p>2) Can order individual tiles for extras/replacement.</p> <p>3) 'Ready to go stes', no gluing or making other bits (bridge, speed bumps, silver foil etc), huge TIME saving. Only exception being that a block may need making for the premier end tile and it assumed you can provide a drinks bottle and a drinks can!</p> <p>4) No need to mount on to another surface, eg cardboard or custom wood.</p> <p>5) No cutting up etc.</p> <p>6) 16 tiles are provided as in the rules, includes the 'start' tile not supplied on some versions.</p> <p>7) Currently 7-10 days delivery.</p> <p>8) Designed to allow better/easier detection between green/black (a lighter shade of green is used which gives a midway result between the white and black areas)</p> <p>9) Successfully trialed at a Robocup Junior training event.</p> <p>10) NZ Developed, helps NZ economy!</p> <p>11) Initial cost of $325 (plus GST and Deelivery) is more than the single roll mat version, but much cheaper when considering having to also provide glue, timber etc plus the time needed to make the working version.</p> <p>Disadvantages:-<br /> Perhaps not as robust as mounted on 12mm custom wood and you perhaps need some sticky tape to prevent adjacent tiles from moving around too easily.</p> <p><a href="mailto:davidt@tamatea.school.nz">davidt@tamatea.school.nz</a> </p> http://robocupjunior.org.nz/forum/topic/size-of-dance-floor#post-15 Wed, 26 May 2010 07:32:27 +0000 CPowick 15@http://robocupjunior.org.nz/forum/ <p>Why the chance in the size from 3m by 3m to 1.8 by 1.8m ? This will restrict the movement opportunities of the robotic dance and the viewing opportunties for the crowd. </p> http://robocupjunior.org.nz/forum/topic/battery-back-cover-for-rcx#post-13 Tue, 09 Feb 2010 20:23:35 +0000 Megan Pledger 13@http://robocupjunior.org.nz/forum/ <p>Hi,</p> <p> I'm missing the grey-ish battery cover for a Mindstorms 1.0 RCX yellow brain/brick. </p> <p> Does anyone have a spare one they don't mind giving/selling to me? </p> <p>[I'm hoping that someone who may have had a dead brick at some time has kept the battery cover.] </p> http://robocupjunior.org.nz/forum/topic/resource-development#post-5 Thu, 16 Jul 2009 15:49:32 +0000 davidt 5@http://robocupjunior.org.nz/forum/ <p>I'm developing a few resources to help with rescue. One is a simulator written in SCRATCH. Although this is different to how NXT-G works, it may be helpful for testing. For example, you can change/test the motor speed, turn angle, distance between light sensors etc all before you make make actual changes to your bot.</p> <p>Any interested SCRATCH users, let me know and I can mail version 1 to you. </p> http://robocupjunior.org.nz/forum/topic/does-anyone-know-this-website#post-6 Fri, 17 Jul 2009 03:17:57 +0000 Megan Pledger 6@http://robocupjunior.org.nz/forum/ <p>There was a website where absolute beginners could practise doing stuff in a simulated environment e.g. how much time should you let the motor run for so that a robo-car turns 90 degrees?</p> <p>It was lesson based and aimed at kids.</p> <p>I never bookmarked it and now I can't find it.</p> <p>Does anyone have the URL for it? </p>
