My first Robot! Looks familiar!
@ March 27, 2009
- Actuators / output devices: 1 x servo 2 x geared motors
- CPU: Picaxe 28x1
- Power source: 4 x 1.2v
- Programming language: Picaxe basic
- Sensors / input devices: SRF05 Ultra Sound
- Target environment: indoor flat surfaces
My first Robot, made with the "Start Here" project :)
I added a switch in the little box between the motors which houses some of the wires.
I'm not sure if adding a switch directly on the power wire is the right thing to do, but it works :)
Also i wasn't too sure about wire sizes. I have been robbing wires and connectors from old PC's and stuff around the house :) The wires on the motors are hard drive power wires. They seem a bit thick, will that make less power get to the motors? The wire from inside CAT5 seems quite good, would that work for these sort of projects?
I tried to use plugs and connectors where I could so I could easily change things around.
An important lesson I learned was planning the layout of your parts. I found it takes 2 seconds to stick a motor or sensor in place with doublesided foam tape... It takes 5 minutes to get it off and remove the tape when you stick it in the wrong place! :)
Any how, My first robot and my first venture into the land of forums too, so please be kind :)
Thank you to Frits for the tutorial and everyone who commented there Great job !

source code
Could you email me the source code you refer to in your description, I want to implement it into my circuit, I want to get some type of guideline with the code for the ultrasonic sensor.

Time for personality
Well done! As Frits said, programming it will be fun. This is where you can give it some personality and make it stand out from the crowd. Perhaps make it throw a tantrum when it gets stuck in a corner.
I usually set mine up so if there are no obstacles after a certain period of time then they look around and change direction out of bordom. Perhaps go towards the nearest obstacle out of curiosity.

Snagging wiring from old PCs is great. The 3-wire cdrom->mobo audio cables can make really groovy sensor wires (pay attention tho, they may have 4 connectors but only 3 seperate connections (common ground)).
The wires you used for the motors should be just fine. You'll likely come into problems using wire that is too small, but going too big isn't that large of a deal (as long as you don't go ridiculously big). CAT5 wire is probably too small for wiring those motors. It should do okay for simple signal lines (like button input), or for tiny motors (like pager motors).

CAT5 solid or braided
Solid copper wires are not as useful as braided ones. When a solid wire bends/folds a couple of times, it will snap. Within the isolation. Nightmare debugging!
Good start. Both the bot and the post.
