Robot using GPS to navigate

[soapyCatfish]

I did a very similar project, check it out: IA111 gps (search at youtube)

Are you still working on it?

Good job!

[Stefanw3]

@soapyCatfish Thanks! IA111 is an interesting project. Well done!

No, I've moved on to much more challenging projects, I am currently trying to automate a Hexakopter to fly around indoors as part of my doctorate (have a look at my more recent videos)

[runeseekerz]

Hi I'm working on a similar project for my degree and currently decided to use c++ to program and using a MN5010HS GPS module and a GPS antenna. I was wondering If I could have a guide on this? Thanks.

[roofy2k]

you're like me man, flying and robotics lol, that is quite a feat to run all of that on a BS2

[Medadrone]

it's amazing ! can you plz send me the guide how to build this robot ? thanks

[TravisTheMartin]

That's so cute. It's like a lost puppy.

[stampmaille]

Nice Job! I did something similar with an R/C boat. I was amazed at how simple and easy the basic stamp was to program.

btw can I get a copy of your source code? I'd eventually like to put this in an R/C plane.

[kakitelecom]

Good

[DronElektron]

That's hard program to do this, my robot will be hafe GPS iblue 747 a+ and compass sensor and NXC code... =)

[quadsforlife]

Hi there, I to am interested in your guide. Would you be willing to send me a copy ?

[mohitruchi1]

hey brilliant piece of work.....m also working on the same but m stuck wid the code....can u please send me the code......

[wanher33]

very good job you have done here. Could you please send me the code/guide? i will be working on the project and want to see how you manage ports, coordinates, registers, etc...Thank you.

[giorgosellas]

thanks!

[giorgosellas]

amazing job! can you send me a guide on how to do this?

[Stefanw3]

@giorgosellas I am in the middle of writing a guide on how to build the robot. I will let you know as soon as it is finished.

[Sniteiru]

@Stefanw3 oh nice waiting for too XD

[vlsverdx]

Nice piece of work stefan.....i myself was stuck with the coding part....can u pls send me the code.....im working on smething similar...thnks in advance!!!

[Hollow9Ichigo]

hey can you plz send me the guide to build this robot, it looks fantastic

[Stefanw3]

I have PM'ed you.

[DhekarAbhik]

hey i am also working on similar project........can you please mail me the necessary guidance for making and coding such robot.....

[theracisthero]

Why Is the movement so erratic?

[Stefanw3]

The robot only gets a heading update every second. This makes it difficult for the robot to settle on the correct heading.

On top of that there are also GPS errors, where the receiver may temporarily give slightly erroneous data to the robot.

[l3mone]

Hey there! I was really happy to find this vid, cuz' i'm working on the same project. I'm using a Forerunner 201 and a model RC plane. I would like to ask you more about the communication with the Garmin. Thnaks

[bsoverns]

Did you buy the Garmin data cable or did you create your own.?

[breezebro]

Way cool! Now if you could send it a new location via Bluetooth and have it go there, that would be totally awesome. Next time post a link with all the info you want to share to help everyone out without having to PM everyone.

[PerusErkki]

Hi!

Good work! Very impressive work. I doing similar project. Your good results with GPS positioning gives me confidence finishing the project.

Erkki Salonen,

[mitesh22]

Hey Stef

I need your help to set up waypoints!

How did you program the map?

[guggsy28]

hi..there Stef.. I really impressed when I saw your robot on the internet. It looks like a very interesting project. I live in Liverpool England and I am looking for similar ways to navigate a robotic boat across a large lake. I would really appreciate any technical help that you could give me as I'm new to all of this technology. Example: How does the gps transfer the information to make the wheels turn? Or rudder in my case..Thanks

[mitesh22]

Hey Stefanw3

This is Mitesh, I am developing a same Robot using same hardware for my final project, would you be able to help me with my code ?

[Stefanw3]

Awesome.

If you have any questions please send me a PM and I'll get back to you.

[JWtheOnlyChild]

is there anyway i can get a copy of the code to see how you incorporated the gps into the Basic code?

[Stefanw3]

Sure, I've sent you a PM with the code.

[ofirbo]

I'll be happy also to see the gps code, thank you!

[somedudeandacomp]

Make it a rock climber and that curb is no match :P

[somedudeandacomp]

Nicely done reminds me of when I was in FIRST Robotics, looks like you made a drunk driver lol

[Stefanw3]

Thanks!

Lol, it does doesn't it...

[epentsins]

Good job can you send any info on this GPS rover.

[Time4TruthDOTorg]

wow this is really nice! how did you connect the gps device and do u need to have any connection to the robot ie a controller? do you just input the co-ordinates and the robot navigates to the programmed destination? please pm me a guide if you can. thank and awsome vid :D

[sspoke]

couldn't u compensate for the 6 Meters by adding or removing 6?

But yah then whats the point for using GPS it will be inaccurate uhh yah.. well GPS is primitive technology needs to be re-amped a bit in the future to be more useful

this would be good for planes autopilot air GPS routes

[Stefanw3]

The problem is one doesn't know which direction the error is currently in, so simply adding or removing 6 metres would not work.

True, GPS is designed for navigation rather than direct control.

[sspoke]

yah i know the resolution of gps is gapped but like all technology it gets deeper and deeper in the pixels. hd tvs and soon HD GPS.. haha.. like the intel chip a transistor is 45,000 Atoms and it was around alot of billion atoms each at the first Pentium processor but now getting smaller and smaller.

[theevilmushroom128]

cooly

[mikelikes2roll]

hehe thanks!

[Stefanw3]

Thanks!

I've added where I got the bits to the video description if you are interested.

The car is a bit broken now, its essentially just motors on a chassis!

[mikelikes2roll]

this is awesome, i really wanted to do this too, but im not really sure how to hook up the gps module.

[Stefanw3]

Hooking up to a GPS module is not as difficult as you may think. I'll PM you a quick guide.

Thanks for the comment!

[1943vermork]

Very nice!

Same thing for me. How to hook up and read the data?

[paloo5]

you are a pioneer, i'm sure in the future cars will not need a pilot, and averybody will live less stressed.

Great

[Stefanw3]

Hehe, should have!

Pity the batteries only lasts about 15-20 minutes. Perhaps if there was a second robot that replaced the batteries on the go... or even better be one of the first solar powered robots in DARPA!

[RokSrakaCar]

did u use board of education?

[Stefanw3]

No, I used a Growbot. It was the only thing I had lying around :).

[adisharr]

Nice job man :)

[Stefanw3]

That's a great idea, would make it a lot easier! Thanks -Stefan

[prmass1]

The applications can be limitless. It is has been used by the military for remotely controlling flying drones.

[GnEeErKd]

i am about to start a very similar project and would like the source code as well if you dont mind

[bangzilla]

cool man, i didnt know basic stamps were so versatile

[roboman79]

tell me what to do to build that.

[DTHuey]

WAY COOL!!!

[86686]

I'm doing a similar project and I would really like to get the source code ..this is my email address, I hope to contact you as soon as possible...I'd really appretiate this favour.

I'll be waiting

[GaijinNH]

Is the source code available?

[Stefanw3]

Sorry about the delay!

Are you still interested in getting the source code?

[GaijinNH]

Sure...I've got a similar project being built soon. I've got a small collection of robots, and I just posted my first YouTube video...

[Stefanw3]

I have messaged you the link...

[kd35a]

Nice robot! Do you also know how parallax own gps-module works???

[RCcarbuilder]

This reminds me of the robot in Star Wars. Where the storm troopers are on the ship, and they are following that little robot. Thats supposed to lead them to their destination. Also, how much money did you spend on this project, I know it most of cost a few hundreds, 5 stars!

[Stefanw3]

Thank you!

Most of the stuff that I used was just lying about.

I think that if you went and bought all the sensors and the stamp it would come to around $200-$250

That would be:

Basic stamp $50 (US price on Parallax website)

Foretrex 101 around $100-$150

Ultrasound sensors £10 each - Stefanw

[concretewhole]

I always wanted to do a aerial vehicle, but the crash is my only concern, too expensive for my budget at the moment.

[robertomanfinfla]

exelente trabajo....

felicitaciones.. !!

[JeromeDemers]

WOW Very nice!

That is my next project after my sumo robots!

J-

[hammod0606]

Thats cool you should check out my robot and let me know what you think.

[aidabab]

Haha great stuff it can get the papers for you in the morning

[JandOlive]

well done!

[rilorilo]

Nice work on programming your little gizmo :)

[alchemyx]

why is it swinging from left to right? caused by gps accuracy?

[Stefanw3]

Thank you for your comments!

Due to the GPS only sending out data every second or so, the robot needs to guess how long to steer for. It copes well with large turns, but tends to steer too much when doing smaller corrections.

So what you are seeing is that it realises it is slightly off-course, tries to correct but steers too much. So in the next cycle it tries to correct and might turn too much the other way and the cycle goes on.

A bug in the coding more than anything.

[alchemyx]

but still it is very cool :)

[chipperpayload]

Hey is there any way i could get your code im developing my own tracking but i havnt had anything to compare with

[madmax678]

cool

[JohnSPals]

Sehr gute mon cher <333
