Yet another newbie's try
@ October 21, 2008
- Actuators / output devices: two geared motors, 1 Servo (also not yet)
- Control method: autonomous (not yet)
- CPU: Picaxe 28x1
- Power source: 9V (with 5V regulator)
- Programming language: Picaxe basic
- Sensors / input devices: SRF05 Ultra Sound (not yet)
- Target environment: indoor, or on flat surfaces outside
UPDATE: He's back, and better than ever... the amazing Nick! * the crowd goes wild* I know, I've not been aktive on LMR for a while, had a lot of school-work and stuff, so I had no time. Well anyway, I've moved my robot onto a diffrent chaissis, (the other one broke) and added the servo and Srf005. I'm all done with building, but well, you know.... programing isn't my thing. But I'm giving it my all, and i should be done in... *he types something into a calculator* 17 Years!

I will post a vid as soon as I get the thing moving.
Update: I am know in a super mood, because i finally found and fixed my problem.It turned out to be a stupid little soldering mistake. But know I have proggramed my robot to go fowards 3000 and then back 3000. SO far so good :). (Will post vid soon)
Update: I have hooked up my two motors and soldered them up to A & B. I have also glued the Castor. But somehow the turning isnt totaly in check, one wheel seemsnot to turn.
Yet another newbies try, this is my first robot!!! At the moment its not much, but you just wait, one day it will rule the world!
so far i have:
A CD plastic hull
2 cool motors (with wheels)
a switch, a batterie and a lot of wires.(If need be, up to 15m)
I have for my "third wheel" a exelent castor, from some kind of thing
I have my super-di-duper PICAXE 28X1, witch i have already used for a super cool blinky LED proggram
and I have a robotic servo(modified for contin. rotations), and mounted atop is.... My SRF005.

looking good

Another step in the right direction

try this code, but I'd check what voltage the batteries (regulator) is putting outfirst. note. your motors could be hooked up different.
main:
let pins = %00000000
pause 1000
high 4 'motor A forward
high 6 'motor B forward
pause 1000
low 4
low 6
pause 1000
high 5 'motor A back
high 7 'motor B back
pause 1000
low 5
low 7
pause 2000
'Turn right
high 4
high 7
pause 2000
low 4
low 7
pause 1000
'turn left
high 5
high 6
pause 2000
low 5
low 6
goto main

I will try this code, but i have to wait for my dad to get me some 9V's, we're out.......again.
Untill now i just used a makeshift battery, a rechagable 6V.

I know, The voltage reg is
I know, The voltage reg is wrong, but i fixed that up berfore connecting a batterie,
So i dont know whats wrong.
My code:
main:
low 4
high 5
high 6
low 7
pause 3000
goto main
I hate it when stuff doesnt work :(

Your voltage regulator isnt

Good spot. I didn't look

code
are you literally typing:
low 6, high 7
or are you typing
low 6: high 7
? (the latter is what you should type)
Also, the motor driver is supposed to get a little hot, but if you could smell it and now no motors work, i bet you fried it.
Try this: remove the motor driver, connect a motor to an output pin (use the darlington driver) and ground. Does it work?
----Or----
I can't really tell from the picture, but it looks like your voltage regulator might not be connected properly.

Great!Now nothing works!I
Great!
Now nothing works!
I plug it in, and try to downlaod, and its says its not connected!
But the motors dont turn any more.
And the L293D still gets hot. :( I'd hate to have broken my picaxe already.
