THAT WAS EPIC!!!!! and i liked the music too, it was a nice touch

[@hwud1]

Yup.. you're right about using different colors to make it run better.. However, i feel lucky that i didn't use many colors..! because, when we went to present these Robots, the tribot's light-sensor (at some stages) couldn't differentiate between colors (black, white, red, blue - it was all black for it) thats because of the high light intensity above, which caused the dark shadows!, so i had to re-program it over there!. so that means, i wud have had to edit lots of conditions for many colors!

[@BeauchampIII]

Good stuff, but the programming for making the robot follow the line is inefective. Instead of having it waddling back and forth you can add a few extra lines which means when it gets onto a straight black line it will run along it, making the overall speed quicker :)

[@hwud1]

I could use only 1 light-sensor on the tribot, and the concept you mentioned, can only be applied if 2 light-sensors are used. (Thats because, if Black says 'go straight', it cant be 100% staight, i.e. it will touch the white part at some time [even while on the straight track], and White command then has to be 'Turn' to get into black part, but again it will goto the other side of the black line!. Unless there are 2 light-sensors which would sense both edges of the black line simultaneously)

This is pretty awesome dudes.....Clever idea....I like it..........

[@SMOshee]

Ahh the good old days :D

[@wasilqayyum]

brilliant work!! :D

[@LoV3rBo11]

its an awesome thing dude...m planning to do robotics for uni..hope i can do this crazy stuff than :)

[@hwud1]

Thanks :)

[@hwud1]

thanks

[@johnkaiser22]

amazing!

[@maazsiddiqui4593]

Good work

[@mattknave4850]

Nice.... my only complain is that the two robots are not "original". There just the two basic robots of the NXT set. Nice job on the programming thought.

[@hwud1]

yup! :)

[@hwud1]

nope.. its done by 'G programming' ... almost all Mindstorms lego videos u see on youtube used G programming!

[@doggy3322]

im makin these in school

[@abraham200060]

Will you have the programming code? You would be so kind to pass it to me :c

[@robson1014]

what's song ?? 5/5

[@derinth]

how to do this robot.?
