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:

Control Panel

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:

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

You will get more opinions with more information. Show us a schematic, show us code, show us more videos. Give us something to comment on. Remember that not everyone looks at this site every day. It will take a week or so for all the regulars to comment.
There are two new videos, and the code is already there, schematic of what??? answer and I will try to post something...

A schematic of the robot. Some of your power configuration sounds inefficient.

You are young and impatient,

The world and any dieties you believe in do not care if you are young and impatient.

Demanding attention won't help :)

Ok thanks for the warning...
Read this walkthrough on power regulation. 9V batteries are never efficient for running your processor or servos.

To feed the motors, I used:

2x connected in parallel

To feed the circuit board/processor I used:

2x connected in parallel

To feed the water pump, I used:

2x connected in series

gsh

This is my scheme of connection to feed the robot, and thanks for the walktrough about power regulation...

 

Yes, you explained that in your post. The reason I mentioned the walkthrough is because the 4xNiMh 9V batteries are not necessary. The room they take up could be used to hold more water or else you could reduce the weight of your robot.

Yah, but then how would I've the power for the water pump, or for the circuit board, I think that's really the only way...But please explain better your idea...

Turning the subject, Have you already seen the new videos??? I saw your robot, the SplatBot Mkll and that's quite impressive, it made in me a new idea, put a servo on the squirt of water of Atomyk-x,that will be quite cool, do you think that will be effective/useful???

 

I've seen four video's, if you've uploaded more then they are not showing up.

Power your pump and board from the two big batteries that drive your tracks. Thats why I said to read the walkthrough on power regulation. Those little 9V go flat too quick.

Aiming your water up or down can chage how far it goes as well as sqirting a candle that might be higher or lower than the bot. Aiming left and right might help you squirt in a tight corner or at least aim quicker than turning the entire robot.

It will depend on the challenge. The problem will be aiming accurately. How does the robot determine exactly where the flame is?

Here are the new videos above in the section UPDATE, but:

That's true the little 9v go flat very quick...This weekend I will try to apply your suggestion of connect th big batteries to the pump...
