Dirt Cheap Robot

I have just assembled a Line Tracking Mouse Kit
purchased from Dick Smith, # K1235, < $20.00 AUD

As Robotics can be a very expensive hobby I thought this may get a few of the younger or
like myself poorer people interested at a rock
bottom level.

Now as it is this is not Picaxe driven
project,
<b>But It Will Be ~ ;o) </b>

For your $20.00 Bucks you get -

Wooden Ply base 3.5mm thick.
Blow Moulded clear thin Mouse shaped cover.
2 x 6V motor/gearbox/wheel assys - L &amp; R.
3 x Photo Interrupter sets, IR LED, TX &amp; RX (PCB and 3 x status LEDs)

Main PCB houses the OTP (once only programmable)
ELAN - EM78P156EP 8 bit Micro pre-programmed.
Motor driver transistors 2 L and 2 R.
Microphone &amp; input circuit, 1 transistor.
4 x AA Cell Battery pack.
Assorted jumper leads plugs, PCB pins, screws etc.

The pre-programmed micro can be swapped for
a Picaxe 18?
The Supply and motor driver will work as is,
but the 3 Status LED lines and 3 IR Eyes (on
their own PCB with 5 pin plug) would need to
be swapped e.g. input pins to output pins to be used with an Picaxe 18? chip.

Everything needs to be self assembled, gearboxes
PCBs and all screwed together took me 3 hrs
to get mine up and running.

I'm sure these things are available world wide
and for the price you can't go wrong.

With a little imagination these units could
be modified and pimp, sorry Picaxed out
fairly easily without breaking the bank.

Hej!

Indeed this can be done, maybe even cheaper; my son and I are currently extending a Velleman light-seeking microbug (<A href='http://www.velleman.be/nl/en/product/view/?id=346299' Target=_Blank>External Web Link</a> with a picaxe-08m brain using Rev-Ed's neat small prototyping board (<A href='http://www.rev-ed.co.uk/images/full/axe021.jpg' Target=_Blank>External Web Link</a>
A lot of these projects can be made.

Hehe... Everyone has it's own &quot;baseplate&quot; they mod to their needs. I used Vellemanns robot frog. It was fun even without the picaxe on board <img src="wink.gif" width=15 height=15 align=middle>clap to turn <img src="wink.gif" width=15 height=15 align=middle> so cool...

I have used the mouse for the same thing - not the LEDs on the line tracker are always on (see the circuit diagram supplied with it - very extensive) and only the receivers need are connexed to an input pin (thats if you are going to use the original config)

We are using the line tracker bit - small seperate board - in our robocup junior rescue.

I am currently using the same line tracking robot (modified) as a testing base for my SRF05, works great for rapid testing!
 
Vic Uni in Melbourne get the DSE line tracker in by the palate load and first year students construct the kitset then deconstruct and hack it into various PICAXE personalities and functions. The Base clone 16F84 kit out of the bag with is a great &quot;no programming required&quot; starter for getting students started and can be made on the kitchen table.
