Abraham

(old)
Well, here is Abraham. He is named after the American tank, mostly because he has tank treads. (M1 Abrams, any army guys around driven one?) He looks cool, but I NEED SOME SERIOUS HELP!!!
1st) Do you think I should glue little segments of rubber band to his treads like this...
or keep 'em bare so I can skid steer better?
2nd) My servo does not work. I am going to hook up ground and volt directly to the batteries this time.
3rd) The start here code does not upload. I get an error message saying that "hardware not found on (whatever the path of my USB cable)"
But other than that he's pretty good! Does anyone know what kind of pwm Vex servos take? I just might have to switch to that.
Here's a couple more pics:

Yup, that's it. Thanks for the help guys!
UPDATE: (old)
My servos are working, but I would like help making a bumper switch so that the robot backs up, turns, and goes forward when it hits something. Any help would be appreciated!
Update:
Everything is working great! Motors turning, servo swinging, etc. I have attached a Sharp GP2D12 infrared analog range sensor and two microswitches with metal arms. I figured out how to write the entire program instead of using the Start Here code, mostly because it won't work. Chris spent a lot of time helping me, but eventually I pissed him off because I didn't read all the manuals. Hey, I piss everybody off at one point or another, Zanthess can testify! Thanks Chris and everybody else that helped! From now on, however, I am not ever going to try and use the shoutbox for help. Probably what I should have been doing in the first place.
weird effect...
Yeah, well until I make a video, that is pretty all there is to see!

nice try
I think that has been a good experience for you. Has your robot finished now without any problems? Do you have any videos shows it in action?

Eh
Well, unfortunately I have long since taken it apart... However I am planning to make a similar bot with an Arduino...

Bump switches are super easy
Bump switches are super easy to make. Grab some paper clips or other goodies plus don`t forget the hot glue and just experiment! When the bumper gets pushed 2 contact points touch, or break. Either way works.
But an easier way is to find some microswitches. You can find a few inside old PC mice.
The manual should explain how to hook up a momentary switch with pull up/down.
After that it`s just a case of checking the pin it`s wired to, and jumping to a "reverse" routine.

Alright dent...
I'm sorry buddy but I have to give you some tought love here. I have 2 or so hours invested here trying to help you. You lied to me twice telling me you read the manual when you didn't.
Now we are at the point where I copied the actual manual page and posted it in a blog post, just for you. Now you have asked how to get your robot to turn and back-up etc WHICH IS SPELLED OUT, IN THE MANUAL!!!
The point i am getting at is why the hell should I waste my time trying to help when you refuse to even open the damn manual? This is frusterating as hell. Now, as I try to help with a basic issue of a switch input you suddenly change over to "help me with my IR" set-up.
You want to try an IR set-up???!! Your robot does not move yet!!!!

Start on page 52 and go to page 64

Page 4 Notes on basic code
Page 18 how to make a servo go
Page 12 how to make your motors go
Page 25 how to wire and code a switch
Now I just wasted my time holding your hand and looking up all these page numbers for you because I have already wasted my time trying to help when I ASSUMED you had read this stuff. I ASSUMED you had read this stuff because you TOLD me you had read this stuff.
Now, do your damn homework and don't ask another question until you have read the fucking manual.
Sheesh!

actually...
I was getting on to something using PULSOUT, but then SERVO worked. Probably because I needed PAUSEs in my code. Thanks Rascal!

Check the hardware
Those look like geared motors, not servos. And if you can't upload the start here code, how do you know the servos/motors don't work ? If you can't upload the code, then the Picaxe board isn't going to do anything.
Yes, try to connect the motors to a battery, just make sure the battery is the right voltage.

they are GM9s
I do not have the servo mounted, because all it does is twitch and make funny noises. I tried the batteries, but no luck. I have now been trying the pulsout command, works okay, but still experimenting because I dont know the time the servo needs and it keeps making stalling noises.
But thanks anyways, dude! Love the help this site has.
