Mobile PC platform for a robot

Posted by on July 20, 2006, 5:48 pm

Hello there,

I have an old Pentium PC Motherboard from which I would like to build a
Mobile Robot. The reason I would like to do this is to use the serial
port, parallel port, hard disk, RAM, USB,etc and build a platform where
I could try out different AI algorithms.

I would like to know how to run a Pentium PC motherboard using
batteries ?

Any help on the above would be great.

Regards,
Rohit

It depends on your power consumption requirements, but usually something
like this works:

There are several others in the market, so google a bit more and you'll able
to find what you're looking for.

Cheers

You could get a large uninterruptable power supply like below for
a simple initial setup. Keep it pluged into a light extension
cord for testing, and just unplug it when you want to go moble.

You can reduce power consumption by using a laptop hard drive and an IDE
adapter to allow the small drive to plug in to the larger IDE cable that
connects to the motherboard.

Or better yet, get an IDE->CompactFlash adapter. Most CF cards

run in one of three modes, including "TrueIDE", which is just
an IDE interface. I made my own without using a PCB, but that
was out of my sheer bloody-mindedness - it took about 3 hours
under the 3x goggles to strip all 40 wires on an IDE cable and
solder it to a CF socket, before encasing all those fragile
joints in hot-melt glue. I was pretty pleased when it worked!

There are places in the US where you can buy these, but the $30
cost plus postage to Australia wasn't my cup of tea :-). The
advantage then is you won't need +12V, because neither MB's nor
CF use it.
