JennToo Radar

[oybrj]

I would really like to build this model, but the links at broke. Does anyone have the files ? :-)

[DavidWehar]

I downloaded the program but a window pops up when i try to download it to the nxt saying that the program is "broken" Do you know what i can do to fix this?

[Lumpiluk]

I am currently working on my own radar with NXC in which it will be possible to choose between a circle or graph output...

How did you manage that the US sensor scans so fast?

And what program did you use to show how the robot "sees" its environment?

[Lumpiluk]

@Lumpiluk OK, figured it out now. I've programmed my own NXT radar for distances as well as light (e.g. for adjusting solar cells). And for the visualization I bet you used NXTScreen, made a texture of that afterwards and then used Voodoo, AfterEffects or similar for match moving ;-) (?)

[Zava40]

Would it be possible to make it move accordingly to its surroundings?

[GEAR1902]

what program did u use for photomontage???

[Intentor]

Amazing, dear Krystian!

Have you tried some real application of this approach?

[KrystianMajewski]

Thanks!

What do you mean by "real application" ?

[Intentor]

I mean some kind of real use for the, let's say, "toy".

Maybe some kind of burglar alarm or navigation system for a robot.

Ok, maybe these aren't some kind of "real application" of the program, but, in fact, it would be nice. At least I kept myself thinking about it...

[KrystianMajewski]

I thought of making an "explorer" robot that maps the whole environment. But it would require a whole new robot and I didn't have the time (and the pieces) to build one yet.

Interpreting the radar data is also very difficult - especially in NXT-G.

[Intentor]

You've used NXT-G? Amazing.

I'm thinking on doing something like an "explorer" that remembers the places (sending data to a computer) using the ultrasonic sensor and a compass sensor, but in Java or C#. However, I'm facing the problem that it'd be hard for the robot to locate itself on the place without starting always on the same point. Maybe some use of a GPS can help... :-)

how did you put the shape from the radar display on the live action video

[DerUnbekannte]

the really great thing about this vid is the overlay effect

[bazmarc]

fantastic work .. great video, i love what you did with the radar overlay on the playback,,, very very cool.

[alexander0025]

how did you get the display to do that?

[KrystianMajewski]

What exactly? You might want to just check out the program if you have any questions.

[linuxkid274]

how would you be able to use this in a program? it would be cool!

[geekman130284]

give me the plans and the program

[KrystianMajewski]

If you can't find them on your own, there is nothing else I can do for you.

[AidanHockey34]

good work you can hear the ultrasoinc sensor when you get close to the robot (the clicking sound) i have the jentoo robot right infront of me.

[laser162003]

would using two ultrasonic sensors improve resolution and reduce errors? the program is on his webpage, there is a link at the nxtasty forums

[KrystianMajewski]

No, the problems with resolution are because of the way the ultrasonic sensor works. Having two will do nothing but introduce problems because the two sensors would interfere with each other.

[ChicoDaRave]

Very cool photomontage how did you made it? What NXT use for measure distance?

[KrystianMajewski]

A UltraSonic sensor.

[ChicoDaRave]

And the photomontage, how did you do that? Really cool

[ericwaak]

VERY VERY VERY VERY VERY awesome... but what was with pressing the right button? and also what language did you use?

[KrystianMajewski]

The right and left buttons are being used to zoom in and out.

I used NXT-G, the programming software that comes with the Mindstorms kit...

[ericwaak]

thats really impresive. nice work

[PawelPiskunowicz]

Could you publish your program?

[KrystianMajewski]

I already did.

[WildernessSurvivor]

can you please tell me where?

[KKKKKKKKKK14]

he kinda did... Go to the link in the description :|

awesome, photomontage really cool
