Hello,
my new robot is now working (or "walking")! It is controlled by 2 Mega128.
You can find a first video at: http://www.tappotec.com/nano_gal...

The rest of the website is in german, sorry.

greetings,
hanns tappeiner

Hello,

Looks cool!

But the video doesn't work for me... I hear the music, and see the intro text ("more than 75000 types..."), but after that its black.

I've got DivX... can anyone else see this?

Ya, sounds good, but video doesnt work. I have DivX codec, but nothing...

Hello Colin, VFX,
the codec is divx 5.1 ... do you have the newest version of divx? I use DivX Pro 5.1, downloaded from www.divx.com
as player I use windows media player and real one player. works with both for me.
But if it dosen't work, I can code every format. mpeg1 or mpeg2...

Please tell me, if it works...
thanks,

Hanns Tappeiner

Hi,

Grabbing the latest DivX codec solved my problems. BTW on your site you link to www.dix.org, not www.divx.com as it should be.

Anyway thats a wicked video! Looks like a really cool robot, plus the video is nicely done!

Good Job!

-Colin

Hello,

thanks colin for your answer!

Ok, I updated the wrong link to the divx website. For others who can't install divX 5.1, I uploaded a MPEG1 video. But the filesize is 13 mb and the quality is lower.

I am very impressed by your work! That Robot is awesome!

I would be very interested at looking at the electronics and software that controlls it. Are you going to be providing this information (schematics etc)?

For those who cant read German (like myself) try this google language tool -

http://www.google.co.nz/language...

Enter - http://www.tappotec.com/nano_gal...
into the Translate a web page text box.

The translation seems to be very good.

Regards

Justin

What is the laser line scanner doing besides making a nice lightnig line?

Hello, thanks for all answers.

1) The robot is a university project (for getting my masters deg.), so may I can publish the plans, if the whole work is done... I'm still working on obstacle climbing, thats a little complex...

2) Laser Line scanner: The "nice lightning line" is parallel to the robots front. With the camera on the robots "head", this line is used to find bigger obstacles. If there is only even terrain, the line is a normal line. If there is an obstacle, (as seen in the video), the line changes, pos an form. With this information nano is able to calculate position and size of obstacles in the camera image, without a second camera (stereo cam).

Ok, I seen It. I downloded DivX 5.1
Nice job, nice video!
So, I would like to make a video from my robot :)

Very nice!!

I've seen your page quite a while ago and immediately added it to my robotics bookmarks.

I'd be especially interested in your laser scanner as I'm currently building one (a scanning 360 degrees range-finder one) for a robot of mine.

What's the camera you are using? resolution?
Any good papers you've based your work on?

THanks in advance and good look with your design,

Stephane,

Nice BOT!

What Bluetooth module is that? Was it difficult to implement BT? Some designers claim you must design your entire project around it, becuase it's so 'finicky'

Awsome!!!
I like the mechanics, and the SW of course!

Very nice

BTW, cnc machining for the parts, 1yr for the design, laser&bluetooth&image recognition&nigth vision.. very very far away of hobbyist capacities.

Um, and you have used the video like a marketing professional XD

I hate to be critical of such a pretty robot, but what practical use would it have that something MUCH simpler couldn't do? That's always been a pet peeve of mine in robot design.

It's called a learning design.. you use it to learn and develop more complex robots, which will eventually turn into something that could be useful. Mimicking insects and other animals is a great way to build self motive robots.

As for something much simpler? A six legged design overcomes many of the shortcomings, and dificulties, of a 4 or 2 legged design. Six leg designs are inherantly stable, as there are always 3 legs on the ground, at any given time.
IMHO a six legged robot, while mechanically complex, is the simplest of self motive robots, to build and control.

Kudos to Hanns for building such an impressive robot. Well built and executed. I wish him the best of success in his further experimentations, and learning.

I know nothing about robotics, but was destined to be a mechanical engineer if the computers hadn't come in my way. That is one cool robot, both abilities and looks!

The web site is one of too few that is both useable and good looking! (usually it's just one of the two. Or worse - none)

What are You using for "muscles". Servos? What power source, and how long does it last?

It is very well done. Congratulation.

Very well designed by the movement of the legs. May I know what is the use of the BlueTooth ?

Hello,

thanks for the postings.

1) NANO actually uses Servos as "muscles". Power source is a 6v lithium batterie.
2) Bluetooth is now used to send commands to the robot (start, stop, search, return home...) and display sensordata on a PC or any other bluetooth device. It will be used in future that more 8 robots can communicate to each other in a Bluetooth pico network.

Hanns, if you're still around could you tell me what you used to implement BlueTooth with your robot, hardware and software? Thanks!!!

Hello,

yes, I can :-)

As bluetooth Modules I use Mitsumi WML C10 modules on the robot, but there are many other modules on the market, class1 and class2, what ever you need.

As development tool I use a CSR Casira development hardware (www.csr.com). With this hard and software it's very easy to implement a RFCOMM Communication or every other bluetooth layer, because of many sample programms.

greetings,
hanns
