Let's Make Robots!

Tankah

remote control

Since I started messing with robotics that I wanted to build a tank, and finally that moment arrived when two Tamiya thread kits and a Twin Motor Gearbox arrived.

Everything started with a sketch:

And as soon as I decided what I want, the assemble process has began.
I have some plastic sheets laying around and I thought they would be perfect to hold all the hardware.

The chassis:

Meanwhile the replacement motors from Pololu arrived and I soldered the caps to remove motor noise.
The ones that came with the twin gear box are very noisy (electrically speaking)

This is the design in an almost final phase:

Later I replaced the plastic things for wood, and I used polymorph for the first time, it´s the best material I have seen in the last decades.

The brains (Xbee, Arduino and my custom motor driver with L293D):

When all the things got in place it was time for a test drive through some obstacles..
I figured that it needs some kind of stabilizer.. otherwise it won´t climb more difficult obstacles, OR it may flip around… (I think i´m just having an idea for another bot)

and… this was what the solution I came up with  :D

I placed an “arm” on the back, it stops the tank from flipping over when its climbing stuff.

It works like a charm  :-)

It´s a lot of fun to drive this thing!! :-)

I live in the US. NW part.

Is there a tutorial I can find that explains programming for the arduino?

Also, you should check this out if you get a chance. http://letsmakerobots.com/node/16707

 

Also, where did you get the treads?

there are no bad questions here ;)

the remote was a wii nunchuck, this was how I used it: http://www.tinker.it/en/Tutorials/WiiNunchuck

for the wireless communication with xbee: http://letsmakerobots.com/node/4118

the threads I can't remember where I get them, it will depend on where are you.. US? EU?

Alright so first of all good job, this may be a bad question on my part, but what did you use to control it wirelessly, and how did it work with the xbee?

Hate the fact that it is remoted, love the arm and the funny thinking! :D

Nice job!

it is remoted for now..  :p
Nice job. I really like the arm. Great idea. :D

Great stuff Guibot !

With a little more power you could have the arm under the chassis and make it hop like a grasshopper.

 Awesome !

There was no video the first time I saw this but that tail is great! Reminds me of a scorpion. Very cool!
