Arduino + Eee PC Robot final (Road to CiclopEee)

[josar1787]

Un compañero y yo hicimos un proyecto similar con camara web puede pasar un pista similar a la tuya y ademas las decisiones no las toma con condiciones de colores sino que utiliza una red neuronal para el entrenamiento luego se implemento con xbee para no tener montada la lapto en el vehiculo jeje si quieres intercambiar conociento escribeme a mi cuenta :p

The programs on the right direction still, it dont need 50 reverse turns to actually get to the finish line. only if the laptop could turn its goddamn head to look around, it could easily overcome its fear of corners

[Souraneel]

its really scared to take those crackin corners

[eried]

@Souraneel hahah as we were!

[MasterThief1324]

@Souraneel Yeah but it "looked" before it turned where other robots just rammed the boundaries before readjusting their courses. Their robots are inefficient because there is the possibility of back tracking on a very tight "U" curve. 

[DedicatedLearning]

Awesome bot...is part of the problem in fluid movement caused by the video source being not absolutely real time? It seems that the source video for guidance lags a little and this may be an issue for fluid forward movement. Just wondering! Again AWESOME BOT! Love the fact you attached a notebook directly to this one! Far better for future programming upgrades or changes!

[eried]

@DedicatedLearning As you said, the problem was the lag over the video detection (also, webcam image and framerate was very bad). The coding was done the last night in the hotel room, so we did not have the time to optimize it :(

The original championship track was very complex (with color signals and other stuff) but they finally decided to use this dumb track with just white borders. (A 'nuclear cannon' to kill flyes)

[soulreaverdoug]

va mas rapido q la mierda ............ lol

[eried]

@soulreaverdoug hahaha es que pasamos de una velocidad tortuga llevando solo partes de cartón, a esa versión super veloz que llevaba bolsas de arroz sin inmutarse

[alienjoe123]

MARIO KART SIM

[eried]

@alienjoe123 well, it can be remote controlled, so maybe it might be very funny to build a lot of these to compete with other people

[benatpc]

Nice last build!!!

Shame you had to tune it down so the cam could keep up :(

[eried]

@benatpc yes :( it was a last minute patch in the firmware controlling the motors (a delay to workaround the camera-road detection lag)

[nickmou]

constractulations!!!

[ChipMunkMusicFan]

did you use the webcam on the netbook as a sensor?

[M2217]

@ChipMunkMusicFan yes

[eried]

@M2217 Right!

[alexanderpas]

if there were a centerline award, you would've won it ;)

[eried]

@alexanderpas hahah :(

[paucarre]

Good implementation, hope you increase the speed next year.

I see that the robot moves with impulses. I think a PID can improve the speed. The error can be the difference between the actual angle of the robot and the angle of the curve of the road.

[assuncaP]

Well i would say you did not had a winning horse. but a nice try non the less.

I would say that the arduino in this basically was for servo control only. The main computations are made by the EEE which handles the video processing and then sends navigation commands through the usb to the arduino.

Anyway you had computational power to do way better. so you definitely need to improve on the video recognition side. Were you using OpenCV?

[eried]

It was opencv, but because the so many bugs of that library (sometimes just hangs) now another member of the team is exploring new solutions.

That time, we had electrical problems, our robot was a lot quicker than that :(

[slush0]

Which software do you use for camera snapshots? I had big latencies (>1sec) with every software I tried and it is unusable for realtime applications...

[eried]

A custom c# software for testing and the final version was in ansi c

[slush0]

but which API? Some direct access or v4l?

[M2217]

@slush0 V4L2 and luvcview descompressing routines (it is UVC based)

[notgud20]

hi very kool dude

did u use image processing for checking the lines or were using some line detection sensor.

If u were using image processing then how was arduino working arnd , were u doing d image processing in matlab or where xactly were u dng.

Can u drop u r email id

[eried]

Image processing was used for checking the lines. In this demo the processing is using C# (at first), but then was in C over Linux.

[rickyprose]

Hi guys, the project is awesome!!!

I'm italian living in Taiwan for business in electronics fields, if you have any idea just let me know!!!

Anyway what song is the first one?

Is so cool!!!

[eried]

Thanks for reply, the first song its "Ding Dingaling" from Vagabond.

[paolonroll]

nice video, its awesome

congrats D:
