Let's Make Robots!

Free Range Robots (IR Beacon) **UPDATED**

**Update 4.14.09***

OK, when you watch the video... 

First of all, it is like, 5 minutes -sorry. There is a point though promise, and that point starts at about 3:40 or so. Now, I can't stress enough, the code is wicked chunky as it was written in about 10 min. It is all "bang-bang" and not proportional at all. The final code should be about 10x faster, much more accurate with a lot less trial and error. For now, this is just proof of concept and indeed it has been proven.

Most parts like the ir receivers have their own datasheets that show how you would set up their product. It's best to refer to that document vs the one that is shown in the picaxe manual as far as other supporting comments are concerned. You should only have to worry about the signal line in the end.

 This is one I worked on a while back that I included a connector(far back side)plus an led that showed I was getting a signal. no need to hook it up to a uProc to know that it worked. just a battery and a tv remote.

I used a pnp transisotor(top right) hooked up to the signal line to the led. This is a 38khz ir reciever btw bought from Mouser electronics. The one used here is the tsop4838


I did everything exactly like the manual and I have used 3 different brands of sensors. All work
Really good dude, it works like a dream. 

That rocks Chris!

So I assume this is the next logical step?


So what kind of sounds are possible with a PICAXE?  I know when I was considering a re-charging unit for my bot, I wanted it to play a mp3 from a piglet nursing a sow :D  Wouldn't that be coool !

that would be awesome
Nursery rhymes don't travel well across cultural bounds. How about that mp3 here?
rik, you've never heard the sounds of a suckling piglet ?  It's pure rapture, the smacking, slurping, gulping, squeeling with joy that I would want to impart to any electronic device charging itself after finding it's mothers teet :)

I'm enough of a farm boy to know what you're talking about. And I get it now. I thought you were referring to a children's song I had never heard about.

That would be an awesome sound effect for a bot sucking juice from the wall indeed. Especially for a whole swarm of them fighting over (N - 1) teets...

Mp3 still appreciated ;-)

I like your wall charger idea. I had the same idea in mind for placement of permenant beacons around the house. However, as soon as some money rolls in, walter is switching to a very big SLA battery for drive --30AH or so. The Dewalt battery pack is just temporary for testing.

On another note, riks cyclops is starting to show some real promise... Walter might have to make a switch from beacons...

Guess I can kiss that TJ-vacation goodbye! Bossman wont let me go.
Got some telescopic work this weekend.
