Autonomous All Terrain Vehicle, aka, AATV.
@ July 29, 2010
- Actuators / output devices: Two 18v drill motors
- Control method: RC for tests, autonomous after tests
- CPU: Arduino
- Operating system: Liking DuinOS
- Power source: 2 18v batteries
- Programming language: Arduino C, and asm
- Sensors / input devices: nothing yet
- Target environment: Outdoors, indoors i you don't mind a scratched floor
AATV stands for, Autonomous All Terrain Vehicle.
Fully custom metal chassis, and "tank" like tracks.
Electronics go inside old modem case.
Motors and drive system is close to complete:
Very good deal for the motors, 18v motors + two proportional controller + gearboxes + two 18v batteries + two chargers, for 30€ brand new at the mall!
They have TONNES of torque, and aren't let down by speed either, gonna need PWM to keep a safe speed, can't wait to drive this thing around!
They also have a friction clutch, so I can set it so that if the motors stall because of something it won't ruin the gears and drain the battery!
Having my custom steel hubs machined, right now the wheels are on by using some fine improvisation
Strong enough to test, but not strong enough for me to trust them there for a long time.
Also got these for a home made lathe, and these for a new version of my coil gun, but that's another project.
Going to finish my other tank track tomorrow, and draw up a sketch of the chassis, stay tuned.
Sketch up picture of motor mount here
Kind of a shitty motor mount system, but it seems functional.
Done a bit more.
Photo is kind of squashed...
Too much speed as you can see in the video, glad PWM exists, right now it's still a bit crooked and stuff, will only be able to make it perfect after having my other tank track finished!
other track is finished.
Tomorrow it will be RC.
Inside modem box:
Kyosho perfex receiver and battery pack, currently charging, getting close to driving it around :-)
Fail! only one of my servos is strong enough to move the button...
here's my stone age motor controller:
It is LOL worthy.
but it works...
Managed to remove the friction clutches, meaning I can now mount the motors properly, but unfortunately I have to remake the chassis...
So instead of keeping the same chassis style I'm going for something more like this:
It will be able to go over bigger stuff like this...

This is the best homemade
This is the best homemade robot ever. I want it to make it by mysel (Excuse me for my bad English)

can i get those motors
can i get those motors online.. they seem wicked, iam obessed with 'em.
btw , the servo u used ,let me guess, u previously used it in an nitro R/C car , rite..
the dirt and grease on it suggests that...LOL

Please just finish the
Please just finish the thing, i am very curious :). I bought my motors and battery etc etc and then saw your tank on LMR. Very curious about the results. Mine will be a bit more industrial/heavy though.
I will add my tank on LMR when it is a bit more appealing to the eyes.
Good work so far! :)

Wicked fast tracks!
Another great project from you! Very creative use of materials to make tank-tracks! That thing looks like it is going to be wicked fast - definitely not the average slow tracked thing most of us would assume it would be! You are probably going to have to come up with some nice soft crash bumpers or you will be punching holes in your house walls,
Can't wait to see your finished bot!
I also like your new avatar - could describe me on a "good" day! :-)

Amazing, put on some horns
Amazing, put on some horns and a colorsensor so it attacks anything red. Ole!

very cool :D
Congratulations amando96, is wich a optimal aspect..
the motor drill are fantastic, where are you bought? in ebay? if not, where was?
thanks :)

Bought them in
Bought them in continente!
Mesmo no hiper-mercado continente, 15€ cada :-)

Rubber roller skate wheels,
Rubber roller skate wheels, had them around and they work quite well apparently :)
