Initial Post - 24/02/2009:

 

This is a Firefighter Robot, (note that the cointaner of water is a old cointainer of pills):

Wich is not completed, it needs a infrared sensor that will enable the "bomb of water", that is a jet of water from a car (here we can also detect a connecting pole wich is to programme the robot ;) ):

But, before I go further, this robot uses a Picaxe 40x:

 Custom Picaxe 40x

It uses a  LM293D to control the motors, (all the printed circuit boards are made at home), to moves itself it uses tracks wich I improve adherence with tape...

As actuators/output devices it has 2 servomotors (Futaba S3001) changed to DC and to 360º (so now they're normal motors), a servomotor used as a servo to rotate the SRF005, a water pump that jets water ;), and that's it about actuators...

MotorsActuators

 

As a CPU it has a Picaxe 40x, wich is connected: to a LM293D to coordenate the two motors; and with the control of the water pump; And this makes the Operative System of Atomyk-x...  

As Power Source it has two 9,6v 2000Mah (Racing Pack) connected in parallel to feed the motors, two square 9v standard rechargeable batteries connected in parallel to feed the Picaxe and the sensors, and more two square 9v standard rechargeable batteries connected in series to feed the water pump...

The Programming Language is Picaxe Basic...

As sensors/input devices it has two SRF005 sonars to navigate, a S320115 follower of lines to detect and follow lines (this one is not applied yet)...

Sensors

 Here is its "control panel", with one on/off switch, one green button for start, and one red one for stop/reset, and connecting poles to recharge all the batteries:

The target environment for this firefighter is indoor, but it can also navigate outdoor in not a highly rough environment...

Here I leave some videos that can show the potential of this robot, I really enjoyed his construction...

I'm having some problems with is programming, when it has been done I will update this post, and show to you new videos...

I leave here also his programme, if anybody can help me, I would be very grateful to that person, this robot will go to a competition in June, on IPG (Instituto Superior Técnico da Guarda in Portugal), and so here I leave also the website of this competition: http://robobombeiro.ipg.pt/

In this website is a highly detailed arena, and the navigation should be applied to that arena:

If someone can help me, I would be very grateful....

Note: Sorry for the bad quality of the pictures/videos....

UPDATE - 25/02/2009:

 So in order to fullfill the request of OddBot, here are two new videos of Atomyk-x |-| The Firefighter Robot squierting water, and fighting the fire:

 

  •  Video 1 - Atomyk-x extinguishing a fire:

http://www.youtube.com/watch?v=gyx_awPD0Xg

 

  • Video 2 - Explanation about the mechanism that has extinguished the fire:

http://www.youtube.com/watch?v=tsfn7SE7hdI

 

I hope you have enjoyed this two new videos as much as I do!!!... ;) -> Bye...

do you connect batteries in parallel?

i think it's not a good practice...

Yes, I connected them, but why it's not a good practice, and what's the solution for having a stronger duration for the batteries, if not connecting in parallel?

i tought there could be selfdischarge between the tow pack

expecially if there is a difference in cell health

but probably i am wrong because google shows manny result about this setup

Well, now I found this:

"We know that the voltage is equal across all branches of a parallel circuit, so we must be sure that these batteries are of equal voltage. If not, we will have relatively large currents circulating from one battery through another, the higher-voltage batteries overpowering the lower-voltage batteries. This is not good." -> from: http://www.allaboutcircuits.com/vol_1/chpt_11/5.html

But like the two batteries I'm using have an equal voltage, there are no problem...But thanks for the warning...

No I don't ever noticed that possible self-discharge beetwen the two batteries, and I intend to continue using this policy...
It looks good so far but I'd like to see it squirt water. So far you've shown it can climb up & down ok.
Ok, today I will post a video where it will squirt some water, in the last didn't it, because I'have not yet a good "full program" to this robot, but today I will show that...And it climbs up & down well! ;)
Really awesome robot, excellent work. Has it been in a fire fighting competitoin yet? Which class are you trying for? Looks like a great competitor, hope it does well.
No it will be in June, it will try for the standard class, and yeah I really hope it does very well....

It seems like the tracks work very well... lol

I wanna see it cool down your desk ablaze... :D that would be freaking cool...

I just wanna see it fight some fires. And WTF costs $643.299??? Seems like this guys would cost $175 at max... unless it is not USD or something.

I WANNA SEE IT PUT OUT FIRES!. Another cool idea is a robot that starts the fires. I shall call him "FIRE STARTER"! muhahahahaha! lol :P

Good job so far though.
