Hey! This thing is still a Work in Progress. Files, instructions, and other stuff might change!

Which servos are needed for driving?

I haven't actually bought my servos yet. Any 360 continuous rotation servo will do, or google changing a servo for 360 rotation.

i looked and the tracks are LWO file, anyway it can be converted to an stl file?

Hi madyicstik, the tracks are exactly the same as on the original design at http://www.thingiverse.com/thing:19170 and can be retrieved from that site. I only added the parts that I modified or created referring back to the original for the other parts. If you can't find them let me know and I will add them to the zip file.

Does this model use the same tracks as the original? Or where can I find the file to print the tracks?

Yes this uses the same track files as the original.

So I have to robot built and all the components, do you have schematics for the driver board or any sources to help with that?

There are several brands of arduino plug in boards for motor/servo control including adafruit. If using servos these can be driven directly from the arduino board. Sorry I don't have any circuits. Try googling arduino servo controller board.

Do you have coding developed? I'm not very skilled in arduino coding.

Actually Oneluc, no. Sorry. I have been unable to get back to this project since I finished the prints. Too many other things going on, and my cancer has given me osteoarthritis causing problems in handling tools and little jumper cables. When I eventually get back to this, I will post some code. Meanwhile try the original design (see the original maker's design at http://www.thingiverse.com/thing:19170 by Krux), he has a simple program for it there. My design just basically changed some design problems I had with his design, and adding some extras like the sensor at the front and a servo mount for a top turret. Hope you get it going, I would love to hear how you go.

Don't worry about it, I'm sorry to hear that. But I've been trying to design a mount of a go pro for that top servo. I absolutely love your design, great job. Thanks for the heads up on the code.

I would love to see your mount when you have it done, very good idea. Please post your thing address in here when you have done it so I can have a look. Good luck with the design and building. Makers make the world a better place.

Will do. I'll most likely have it done by tomorrow.

What are the dimensions?

Hi PradaJ, dimensions are I believe on the original project site, but roughly with tracks but without top servo:-
W= 180mm, H (without servo)= 94mm, L (with ultrasonic sensor) = 165mm.
Hope this helps.
