"Slunk"

UPDATE: This project is closed. I'm using the (working) parts for a new bot. But I had a battery question (below).

..................................................

So, I created my own first robot following the Start Here instructions. I was only able to get one picture:

I decided to upgrade the robot itself to look more presentable when i tried to show it off on my favorite website. I would also document this build, step by step.

Materials:

1 Picaxe 28 project board

1 4 AA battery case from RadioShack

1 futaba s3003 servo

1 sharp ir sensor, attached to servo wheel

2 piece-of-crab DC motors from SolarBotics

1+ Red Stribe Jamaican Lager

To each piece-of-crap DC motors from Solarbotics, I've soldered a female jumper. I've also soldered header pins to my project board, for easy hookup/unhookup of motors and sensors.

Sensor hot-glued onto the servo wheel:

 I chose the RadioShack battery case because it had a handy on/off switch. I attached the piece-of-crap DC motors to the removable lid so I don't have to disassemble it to change batteries.

Attach a piece of paint-mixer stick on which to place the servo. A 25-cent plastic toy bubble works as the front wheel.

This leaves some "trunk space" under the power box, where i can tuck away all the extra the wires.

While tucking connecting the sensor and tucking the wires underneath, disaster struck. the terminal on one of the piece-of-crap Solarbotics DC motor broke. Off. All the way inside the housing:

.... which pretty much puts that motor out of commision until I can get a replacement. 

...To be continued ...

-----------------------------------------------------

UPDATE

okay, so I haven't found new motors for these gears. Instead, I got a Tamiya twin gearbox. It looks so much different that it will end up being a new robot entirely. So this one is finished. Done for.

However, this project brought up a concern:

BATTERIES!!!

The 4 AA battery pack in the picture does not power my 28x project board. I've tested it; 5.25V. But when I connect it to the project board, nothing happens. At all. The first time I connected it, my picaxe got REALLY hot, really quick. So I disconnected it until I could figure out what was going on. I tried monkeying around with it again, and now it doesn't power the board. Any ideas why this would be?
