My first Robot, called Duckie (or Sniffer if you like)
- Actuators / output devices: 6v sealed gear motors
- Control method: autonomous
- CPU: Picaxe 28x1
- Power source: 3 AA cells
- Programming language: Picaxe basic
- Sensors / input devices: Sharp GP2Y0A21YK0F IR sensor
- Target environment: indoor flat surfaces, carpets
I started this back in May but he, she or it had the servo and sensor mounted on top of the base. I found it kept missing ‘seeing’ obstacles so recently moved the sensor to the front of the base. Well it still messes up sometimes but now it has that nice tilting motion like Fritsl’s robot in part 2.

A top-down shot giving the slightly misleading impression that it's fallen apart (it hadn't quite in this picture!)
The code is based on the standard code that use to be posted here, but simplified and modified to work with this configuration.It doesn’t look to see if there’s anything interesting to go and explore and also it doesn’t count how many times its turned in those places where it should back up and turn around.
Things to do:
Refine code.
Add another sensor at the lower front.
Add a few LEDs.
Add some squeaks and beeps.
Teach it to make a decent cup of tea!!
(p.s.Excuse the messy carpet in the video, the culprit was in the vid!)
Lol, frankly it looks like
Lol, frankly it looks like it is falling apart :D
It's like it is the "start here"- robot that has accidentally swallowed a lunchbox :D
I cant wait to see the video. Make sure to optimize the code so that all the "pause" and "wait" are minimal :)
I know, I know. Actually
I know, I know. Actually it was falling apart in the end!
It's rough and ready, I wanted to build it rather than think about building it and this was the quckest way for me.
:-)
OMG, just saw the video! It

Nice work NE555V (timer?) - i like the bounce ... who needs stinkin wheels!

No wheels? I bounce up and down in the same spot then.
Yes
I used to know him. Isn't he (ahem) "dual channel" now?
I like the little backstop you put to stop him (it) going right over when it accelerates.
... I wonder if it would be possible to make a wheelie-ing robot.

- Now there's an interesting concept!!
very well, man. the robot
HE555V,I like the way that
HE555V,
I like the way that you have the sensor / turret "lock" on an obstacle, and move away from it until clear, before continuing.
I haven't thought of that. It makes perfect sense to me now though. I was just backing away, continuing my scan. Sometimes I'd find myself painted into a corner, backing away, and then returning to the same place, only to repeat it over and over.
Thanks for the insight.

I got it to do that purely
That idea was inspired Fritsl's robot's which quaintly "examine" the obstacles as they pass it.
I have no idea how mine does it though I think there's a bit of chaos in the works in there somewhere!
(Probably impreciseness due to my bad coding and electrical noise from the motors or something.)
Look left, look right..
Look left, look right.. something to the right? Steer left, while turning head to the right.. untill head is far enough to the right fo rus to pass..
No more magic than that :)
Thanks frits!,I'll try
Thanks frits!,
I'll try that. It's so simple, and I was scratching my head looking at a more complex way. Duh...
In retrospect, I guess I really had a brain phart when I came up with the "back up - then try again" code.
