this year regular upper secondary (vertical limit) is harder than last year a lot..haha... the robot need to climb up and climb down the pole, collect the ping pong ball, then move from pole A to pole B ITSELF and climb again.. wah..nice....
how about the lower secondary category? is it really the aluminium used is not yet opened n full of water inside? is it both tins on d map is full of water?
yes...2 aluminium are loaded (full of water)... 1 is fixed on the sector A, and the other 1 will randomly put on 1 of the 4 circles..... but we will announce before quarantine time..
so we need to think how to design 1 motor can open and close the robot's arm, when robot's arm close until the limit(can't close already), the motor will push the gears and push robot up.... this is idea only, who still remember last year NRC "robot energizing" event, got few teams use same idea to get "solar"...hehe...
jason , my GB bought 2 new sets of NXT , they r the same with the one we used last year , but there are no software inside the two boxes . Does this mean that we use the old one ?
1. download the file slow because ur net slow lo..haha... 2. for the primary school event, if the ball fell off, the robot still can continue the track until finish box, but u lost 35 points(ball's point), can't start again...if u touch the robot, the game is over...
for vertical limit, the robot need to start at the bottom of the first pole,start on black line or opposite is up to u..as long as the robot's size is not exceed the maximum size...
not necessary to buy something then just can enter the competition...but we SUGGEST the schools buy the map for practice...or buy some extra sensors or parts for improve ur robot...
sorry, i didn't measure oh...haha ur school buy the playing field or not? if got then u can measure ..if no better buy lo...because we will use same size playing field during competition..
err.. my school did not buy the map. we dont have money to buy it. the map cost around rm400 plus lower sec map around rm800 thats too much for my school
hi mr. jason... i want to know the length between the pole A and pole B.. u know what, my student said it is impossible to make the robot to climb up the pole...aiyoooo
haha..nothing is impossible... the schools in pahang & sarawak can make the robot climb up the pole already... but now the hardest part is robot need to move from pole A to pole B itself and climb pole B.. it really tough, that's mean who can do it who will be champion lo...maybe..
mRd : we can use the " benang@getah" as long as the parts is from LEGO EDUCATION SET...
wilson : for treasure hunt, if the robot want to trigger the switch A, it need to follow the line A until any part of the robot touch the wall, then it counted trigger the switch A already, same with C and B.
yes..for upper secondary event,the whole robot need to climb up the pole...can't just transform the robot from the bottom of the pole and get the ball..hehe..
2 or more motors can share 1 output port, NXT has 3 output port right? that's mean we can run a lot of motors at a time, u just use 2 convertor cable to connect 2 motors first, then use third convertor cable connect the motors with 1 output port... eh..very hard to understand right? wahaha..nvm, i will take a photo and post on the blog... but in this case, the robot can't use motor's degree sensor any more...can use timing only..
hi mr jason... in upper secondary competition, can we drop the first pingpong ball after we get the ball? Or we must bring it along while getting the another ball?
For upper secondary, the robot can drop the first ping pong ball after robot reached the bottom of pole A(get the points already), but please remember is not the contestant take the ball from robot, the robot must drop the ball itself... if u touch the robot or ball.......GAME OVER...haha..
no problem...the robot can continue the mission....but if the robot DAMAGE the playing field or obstacle purposely...we will consider the team is game over...
if i use rcx for primary event, have any idea how to detect ping pong ball n grab it.... since cannot use ultra sonic sensor... oredy finish design for vertical limit but can't test it yet coz do not have map yet... bos do not approve to buy map... so mahal lo...
haha....no need detect lo....just use timing lah... huh? how come u find the solution for primary and secondary ah? u r student or teacher or parent ah? so rajin...hehe..
teacher lo.... not so rajin la.. i teach primary school n my wife secondary skool... so i train both lo... now i have 3 set, 1 rcx n 2 nxt... need 1 more to participate 4 lower secondary...haiyo my wife punya boss banyak kedekut la... do not test yet la... i do not have map.. so sad..
ic...mRd...good lah..can try 3 events together mah.. if have time try open category also lo...nice leh...haha... ya...i just post the vertical limit solution...
vernon min, yes, u can use the light sensor to detect the black line and take the ping pong ball, but u need to design 1 arm to get the ball...u can refer to youtube....a lot of video..
Hello, Jason, Wonderful vertical limit solution, Pls. let me know how did u fix the grabbing + locking mech. Hv u used motor(servo or the one with converter cabel) to move the arm? I tried different things like gear down(power up) arms, but it slips with nxt's weight. Pls. upload a few pics of ur sample solution from diff. angle, if possible. Thnx.
eh...actually the sample solution is from thailand 1.. so i also don't have any robot picture ...sorry... but from the movie u can c that they used same 2 NXT motor for climb and follow the line...and third motor for lock the pole and push ball... if third motor lock the pole, then 2 motor will climb up the pole but if third motor open, 2 motor will push the robot "terbalik" and follow the line to pole B....then use third motor lock the pole B and climb the pole B.....
hi Jason, Thnx, but any idea how the entire model stays up just with locking mech when it reaches up to grab the ball, 2 climbing motors are stopped at the top. It is not slipping down. 2 climbing motors haven't used any grabbing mech, right? What kind of locking would be able to hold the entire model? Pls. acknowledge.
The date of competition will be announce by JPN later...we also don't know yet woh...sorry about that...Pahang and Selangor maybe July start competition...
i familiar with robolab but primary student hard to understand it, in robolab we have JUMP function, in NXT-G do not have, so how to come out from loop, for example if use 2 light sensor than if see both dark i want to end loop, so how.. my light sensor reading is 47 dark & 63 light
ic...mRd, actually u can use 2 light sensor loop to end the program when 2 light sensor detected the black... i think now u use loop forever to run the follow line right, change the forever loop to 2 light sensor loop.
i mean how to use 2 light at the nxt program cause if i set normaly cannot set the light sensors work at the same time can you teach me how to set at the same time
for lower secondary, my school bought 1 set of map, it's not included with the aluminium tin and the switches A,B and C. what are the switches actually? is it a button or just a wall? and where can we buy the exact tin, just in case that the base or the weight of the tin is different than the usual tin we use...
aiyo...i still don't understand what means by use 2 light sensor at the same time la... work at the same time for detect black line?? follow the black line?? separate color or what?? can u explain what u want?
this year regular upper secondary (vertical limit) is harder than last year a lot..haha...
ReplyDeletethe robot need to climb up and climb down the pole, collect the ping pong ball, then move from pole A to pole B ITSELF and climb again..
wah..nice....
is there any limit for the number of motor?
ReplyDeleteno limit for the motors and sensors in regular event...but the RCX/NXT controller only can use 1 unit ...
ReplyDeletedimension of the robot is not restricted is thr any wrong?
ReplyDeletebefore robot start, the robot's size can't exceed 25cm X 25cm X 25cm , but after robot start, the size is not restricted already...
ReplyDeleteermm.. excuse me, sir.. i cant download the rules.. pls help me =D
ReplyDeletejust right click the download and select "save link as"...
ReplyDeleteStill cannot download
ReplyDeleteya.... I also cant download it!!
ReplyDeletebut i used my friend's laptop can download woh...

2.try Internet Explorer or Google chrome
3.change ur computer or laptop..haha
HOW BOUT PRIMARY SCOOL... OR ALL FOLLOW PHILIPINE WRO RULE
ReplyDeleteAll follow WRO events, but we change some rules, so NRC teams please refer to rules here... thanks...
ReplyDeletehow about the lower secondary category?
ReplyDeleteis it really the aluminium used is not yet opened n full of water inside?
is it both tins on d map is full of water?
yes...2 aluminium are loaded (full of water)...
ReplyDelete1 is fixed on the sector A, and the other 1 will randomly put on 1 of the 4 circles.....
but we will announce before quarantine time..
walaoye , climbing is not easy already, now wants to move and climb again. very "jialat" la. Any idea on overcome the challenge ?
ReplyDeletelolz i like your expression, "WALAOYE" XD
ReplyDeletewahaha...really walaoye...
ReplyDeletebut philippine can do we also can do 1...
because.....MALAYSIA BOLEH mah...
hehe..
so we need to think how to design 1 motor can open and close the robot's arm, when robot's arm close until the limit(can't close already), the motor will push the gears and push robot up....
ReplyDeletethis is idea only, who still remember last year NRC "robot energizing" event, got few teams use same idea to get "solar"...hehe...
tkasih jason tee... good job
ReplyDeletejason , my GB bought 2 new sets of NXT , they r the same with the one we used last year , but there are no software inside the two boxes . Does this mean that we use the old one ?
ReplyDeleteyes...if the school got software already, we didn't suggest buy the software again..because the software is same...
ReplyDeletewah , u reply so fast . TQ V M . i am downloading the rules but how come so slow ?
ReplyDeletejason , 4 the primary event , what happen if the ball fell off from the robot ? do we start again or what ?
ReplyDeletejason , what happen if the ball fell off the robot ? we start again or what ?
ReplyDelete1. download the file slow because ur net slow lo..haha...
ReplyDelete2. for the primary school event, if the ball fell off, the robot still can continue the track until finish box, but u lost 35 points(ball's point), can't start again...if u touch the robot, the game is over...
haha...i will reply all the question when i am online, but actually i online every night...hope this will help u all....hehe.....

ReplyDelete2 minutes per round, each team 2 rounds...
ReplyDeletefor vertical limit bot start on black line or opposite...
ReplyDeletedo we need to buy some thing to participate... coz what i heard... guy from melaka said that we need buy map first.than can participate
ReplyDeletefor vertical limit, the robot need to start at the bottom of the first pole,start on black line or opposite is up to u..as long as the robot's size is not exceed the maximum size...
ReplyDeletenot necessary to buy something then just can enter the competition...but we SUGGEST the schools buy the map for practice...or buy some extra sensors or parts for improve ur robot...
ReplyDeletewhen the NRC competition,Selangor?
ReplyDeletenot confirm yet..normally is Jun or early July...
ReplyDeletewhat is the length of black line in vertical limit?
ReplyDeletewe didn't measure...
ReplyDeletevery obvious right..the line is from pole A to Pole B ...
actually i want to know the length between pole A and B
ReplyDeletesorry, i didn't measure oh...haha
ReplyDeleteur school buy the playing field or not?
if got then u can measure ..if no better buy lo...because we will use same size playing field during competition..
err.. my school did not buy the map. we dont have money to buy it. the map cost around rm400 plus lower sec map around rm800 thats too much for my school
ReplyDeleteic....like that ok lah...
ReplyDeletei will measure for u when i get the playing field...
hi mr. jason... i want to know the length between the pole A and pole B.. u know what, my student said it is impossible to make the robot to climb up the pole...aiyoooo
ReplyDeletehaha..nothing is impossible...
ReplyDeletethe schools in pahang & sarawak can make the robot climb up the pole already...
but now the hardest part is robot need to move from pole A to pole B itself and climb pole B..
it really tough, that's mean who can do it who will be champion lo...maybe..
pahang&pahang start olady?? or just practice..
ReplyDeletejust practice...but i heard haven't autonomous yet...ganbateh...
ReplyDeleteMy school just start to think for the climbing part. Plz help!!!
ReplyDeleteGood luck lo...
ReplyDeletePlz post some good ideas here. TQ.
ReplyDeletewhich part of sarawak team know hw to solve the climbing parts....Can i noe??..ty.
ReplyDeletewe all knew that the upper secondary school event is very tough..we r thinking and try to find some idea for schools.....
ReplyDeletecan we use something like "benang@getah" as add on
ReplyDeleteJUST NOW I WATCH VID FROM UKRAINE TEAM WRO 2009, XKAN XDE KOT OUR NATIONAL TEAM PUNYA VID... UPLOAD LE KAT YOUTUBE KE... JUST FOR INSPIRATION
ReplyDeletecan you explain in detail about triggering the switches in treasure hunt?
ReplyDeleteCan i noe the distance between pole A and B ?tQ..
ReplyDeletemRd : we can use the " benang@getah" as long as the parts is from LEGO EDUCATION SET...
ReplyDeletewilson : for treasure hunt, if the robot want to trigger the switch A, it need to follow the line A until any part of the robot touch the wall, then it counted trigger the switch A already, same with C and B.
You can donwload the WRO video from SASBADI website, nrc.sasbadi.com
ReplyDeletethe whole parts of robots much be up to climb de pole?
ReplyDeletecan use retail nxt for tournament??
ReplyDeleteyes..for upper secondary event,the whole robot need to climb up the pole...can't just transform the robot from the bottom of the pole and get the ball..hehe..
ReplyDeletecan't use the retail set for the NRC....only education set, we will check during competition...
ReplyDeleteAny idea how to run more than 3 motors on 1 NXT?
ReplyDeletefor vertical limit, do the robot need to move from pole A to pole B by it self?
ReplyDeleteor the student have to carry the robot to pole B by hand?
2 or more motors can share 1 output port, NXT has 3 output port right? that's mean we can run a lot of motors at a time, u just use 2 convertor cable to connect 2 motors first, then use third convertor cable connect the motors with 1 output port...
ReplyDeleteeh..very hard to understand right? wahaha..nvm, i will take a photo and post on the blog...
but in this case, the robot can't use motor's degree sensor any more...can use timing only..
Yes...for vertical limit, the robot need to move from pole A to pole B itself, students can't touch the robot...if touched then GAME OVER...
ReplyDeletehi mr jason...
ReplyDeletein upper secondary competition, can we drop the first pingpong ball after we get the ball? Or we must bring it along while getting the another ball?
For upper secondary, the robot can drop the first ping pong ball after robot reached the bottom of pole A(get the points already), but please remember is not the contestant take the ball from robot, the robot must drop the ball itself...
ReplyDeleteif u touch the robot or ball.......GAME OVER...haha..
jason , on march 25 , u said after the robot starts , the size of the robot are no longer restricted . that means the size can be bigger than 25 cm ?
ReplyDeleteyes....for vertical limit event....after the robot starts , the size of the robot are no longer restricted..
ReplyDeletecan use nxt ultrasonic sensor in rcx or not???
ReplyDeletehaha...can not woh....rcx not support ultrasonic sensor....
ReplyDeletehaiyo... rosak program... i Thought want to use rcx for vertical limit.. rcx is lighter...
ReplyDeletehaha...of course RCX is lighter than NXT a lot...especially motors....
ReplyDeletejason, what happen if one of the obsticles 'tercabut' when the robot pass by ?
ReplyDeleteno problem...the robot can continue the mission....but if the robot DAMAGE the playing field or obstacle purposely...we will consider the team is game over...
ReplyDeletejason , does the robot hv 2 stop at the finish box ? what if the robot stops a bit out side the box ? i mean half in half outside.
ReplyDeletewhere to get the nxt program???i wan de
ReplyDeleteFor primary school event, the robot no need stop at the finish box, just pass through the finish box as long as the robot no miss-tracked....
ReplyDeleteHi, hahaha, what do u mean the nxt program?? or u mean nxt software?? if software u need to order from sasbadi...thanks...
ReplyDeleteif i use rcx for primary event, have any idea how to detect ping pong ball n grab it.... since cannot use ultra sonic sensor... oredy finish design for vertical limit but can't test it yet coz do not have map yet... bos do not approve to buy map... so mahal lo...
ReplyDeletehaha....no need detect lo....just use timing lah...
ReplyDeletehuh? how come u find the solution for primary and secondary ah? u r student or teacher or parent ah? so rajin...hehe..
mrd do u mind to tell me how long u use to get 100points for vertical limit?
ReplyDeleteteacher lo.... not so rajin la.. i teach primary school n my wife secondary skool... so i train both lo... now i have 3 set, 1 rcx n 2 nxt... need 1 more to participate 4 lower secondary...haiyo my wife punya boss banyak kedekut la... do not test yet la... i do not have map.. so sad..
ReplyDeleteic...mRd...good lah..can try 3 events together mah..
ReplyDeleteif have time try open category also lo...nice leh...haha...
ya...i just post the vertical limit solution...
Helo Jason , any idea or solution for primary school event
ReplyDeleteprimary school event very easy woh..just follow the line only...u try oredy??
ReplyDeleteBut no easy to hold the ping pong , is it need to use light sensor?
ReplyDeletevernon min, yes, u can use the light sensor to detect the black line and take the ping pong ball, but u need to design 1 arm to get the ball...u can refer to youtube....a lot of video..

ReplyDeleteCan use rcx motors with nxt set in the competition?
ReplyDeletewhen nrc will announce date of competition? two weeks before competition?
ReplyDeleteyes...u can use rcx motors with NXT set during competition..
ReplyDeleteThe date of competition will be announce by JPN later...we also don't know yet woh...sorry about that...Pahang and Selangor maybe July start competition...
ReplyDeletei heard that competition will be on saturday only is it true?
ReplyDeletehuh? no la...normally the competition will be on weekday...
ReplyDeletejason , how 2 run 2 sensors at a time ? dun know how 2 program . pls gv guidance . Tz
ReplyDeleterun 2 sensor at a time??
ReplyDeletewhat sensor? what is the purpose??
NXT or Robolab software??
light sensor . NXT .
ReplyDeletethen...what is the purpose?
ReplyDeleteuse 2 light sensor for what??
i familiar with robolab but primary student hard to understand it, in robolab we have JUMP function, in NXT-G do not have, so how to come out from loop, for example if use 2 light sensor than if see both dark i want to end loop, so how.. my light sensor reading is 47 dark & 63 light
