actually something i saw in a recent video is that those batteries get their voltage multiplied then metered back down to 9 volts so essentially those batteries give full and consistent voltage till they are dead, but also this is more about the programming aspect of the robot.
To solve the problem with the loops you could try to make the bot create a map of all parts of labyrinth he passed and when he is on a new knot he could eliminate lines which will take him to his previous positions.
Very clever! However, I have a question: if there are multiple routs to the centre and it learns both, how does it judge which to go down? If they both have the same amount of turns, how does it work out which is best?
It doesnt learn two paths. Like he said, its literally left leaning meaning that it will hug left wall until a successful path is solved, thats the only path it will know.
What does the robot do if it can't complete the first pass in the time alloted? The original rules for line maze (using 1/4" tape instead of 3/4") made it very difficult to complete a first pass in only one run.
Are you following the depth first search algorithm? And your sensors are mindblowing. Also what motors are you using? Normally DC geared motors low torque don't stop at the moment when we signal them to.
+Avirup Basu Its a pre built robot, he just had to code it. You can buy that robot here : www.amazon.com/gp/product/B003XGJ3XS/ref=as_li_ss_tl?ie=UTF8&camp=1789&creative=390957&creativeASIN=B003XGJ3XS&linkCode=as2&tag=intorobo-20
+Avirup Basu well. you have same problem with me, he use metal geared motor and i use small dc motor low torque with plastic gear. i think that is the problem. so we can use metal geared motor and i think that is strong enough to make robot turn left or right at the moment.
how did you remembered where to accelerate and break before the turn. how did you stored the distances and time and things like that? could you give some suggestion about that? and also the perfectly smooth and quick turning. please
hei urs so simple and very efficient. i also did 1 follower its not much efficient as yours and not able to get your speed at al.and how much big you codded for this
hey dude.. i m using QTRsensor array and builded a bot.. but i m not getting how it stores in memory..means how it gets the shortest path... i m not getting to solve maze if there are multiple loops by left and right hand algorithm

I am really looking forward to build such a bot for my own. Can you share your source code or probably the literature and references that you followed for building your own robot. That will be of great help to me. Thanks for considering my request.
ah back when geared brushed motors and AA batteries were as good as it got for hobby robotics
Actually. Triple A

It was 12 years ago!! Woah!! My mind is blown dude! Fantastic! 👏👏👏😵🤯😎✌️👏👏👏🍾🎉

I want to see the coding behind this. It's amazing

that's pretty amazing. i'm impressed.
480p for 14 years ago is almost as impressive as the robot!
i would make one a bit higher, to scan 360 for the end, and make it jump to it haha
This is nice! Easy to understand what it does, but hard at implementation. Cool stuffs! :)
I see your algorithm... thanks a lot dude
i'm aMAZEd!
That is so amazing!!!
The birth of iRobot, the vacuum cleaner.
very impressed. Love it!!!
why do i keep imagining this bot is somewhere in the backrooms searching the exit

@@AkshayAradhya he actually made the company which sells those lol
Depth First Search Algorithm ? This is just beautiful!
check out this one ruclips.net/video/afI6EA9NwYM/видео.html
aun que no lo crean, el problema de ese robot es muy simple tiene puras condicionales sobre condicionales
Awesome. great job on it
That's awesome! =D
Very nice robot and programming! I wonder how many years it will be when this video gets recommended again by youtube's algorithm.
do you have program ?
can you give me ?
nice project!
impressive speed, but does your algorythm if there is more than one possible path?
wowww dude impressive
how is it turning coz clearly it wasnt using its wheels to turn
one question can you some how a make a case for the robot so his body parts dont show up. other than that... GENIUS

Hello, how do you put music in the intersections? can you send the code? thanks
I saw this video in 2009 and bought the bot today. 13 years of passion.
Its ok but there is a serious problem with your algorithm. I guess you didnt want to deal with NP problem.
how is the robot able to speed up on the straight path in the 2nd round without using any kind of encoders?
Whauuu!! Bravissimo. Di dove sei? Io sono italiano.
how do you balance the bot against giggling?
it's amazing how u did that??i mean how it came back and goes on other path?will u pls send the program
I want to build it too can you give me some reference website>>??@BenPololu
So the maze only shows the paths.
How does is accelerates on straight paths... I'm making one... any solution or logic or reference?
Hi i have question about line flower robot pelease help me
Thats pretty sick
That's cool as shit
Can I have the code please?
the robo be doin side quests first
LEFT LEFT LEFT LEFT LEFT
HR2
I couldn ´t do that…
This isn't the std 3pi code you can download from Pololu is it? Is this code available for download somewhere? Thanks!
if you notice, robot just using the left wall rule.
He just turn left, when it possible. That's all
sorry 4 my english, i'm just russian nerd :D
14 years ago
Robot wins.
Genius
Wow cool
damn
hei urs so simple and very efficient. i also did 1 follower its not much efficient as yours and not able to get your speed at al.and how much big you codded for this
This reminds me of Dijkstra's shortest path algorithm!
how can i build it ??
hey dude.. i m using QTRsensor array and builded a bot.. but i m not getting how it stores in memory..means how it gets the shortest path... i m not getting to solve maze if there are multiple loops by left and right hand algorithm
where can buy this program ?
would you mind sharing your code for line-following
Hi, i need to make a project with a LeGo mind storm, and it's a maze solver with same conditions, can you help me with this problem? thank you

I would love to see the code behind this wonderful creation 😍...
How is it storing the best path...
muito poggers ooooo benpololu
Nice :D
Can someone please help me to build such a robot?(i don't wanna use the 3pi hardware, maybe something new we can design)
Please let me know if you are still interested in this
Real life aplications for this? (Serius question )
AI
I know I'm late, but you could search damaged houses after victims with the algorithm or drive a autonomous car with it
How would I get one of those. And do they all do that or do you have to program it.
That is crazy cool 😲
amazing
so he is doing tree travilling !
And this was 14 years back...
Also it would be great for searching lost people in a Haunted maze....(sigh it happend to me)
it's too bad it's not compatible with ti-basic.
❤
woow
Hi Which simulation software is used for checking maze solving algorithm
super video................
Can you provide program for this maze?
That things a litteral genius
Does it use recursive backtracking?
Which algo is using here ?
can I have its code and hardware design please ?
Sir, would you like to share this source code? Please....
It's Pretty Awesome Man !
Which motors are you using ? Please provide their specs.
could he figure out loops?
How to make it plays tell
amaziiiiiiiiiiiiiing :D

Hello,
you could send the code of the maze solving who also play in the intersections, as seen in the video, for my 3pi;
Hi i have question pelease help me
Jesus te ama muito!!! Tenha certeza dissoo
Can I get the code?
please bro the code

I know I'm 4 years late, but they put a link in the description for buying the model of robot they used: www.pololu.com/product/975
Nice
Awesome
Wow it’s amazing
cute little bugger!
That's kinda cool.
Great work!
Thats cool! how did you make that?
