Little 8R

If the Google video is not working, please see the video here


I proudly present part II of the "Little 8"-project!

All I did was actually to cut the bumper's wire, place a ER900RS-02 instead of it (tried to have both, but nogo), fire up my old joystick Black Box.. and camera.. and go :D (20 minutes max)

The code in it:

'What is recieved for any 9 possible positions of jopystick + 2 buttons:
'ABC
'DSF
'GHI
'X Y
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
'high 0,1,2,4' set all pins conected to motor as output pins
''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''

high 0,1,2,4
main:

serin 3, T2400, b0
select case b0

'case "X" - not used to save memory in Picaxe 08, tricks are performed with trick-data send from outside
'case "Y" - not used to save memory in Picaxe 08, tricks are performed with trick-data send from outside

case "B"
let pins = %00010010

case "C"
let pins = %00010000
case "A"
let pins = %00000010
case "F"
let pins = %00010001
case "D"
let pins = %00000110
case "H"
let pins = %00000101
case "G"
let pins = %00000100
case "I"
let pins = %00000001
else
'Case "S" for "Stop"
let pins = %00000000
endselect
goto main

' There you go - total drive-control in every way from serial input..in 104 bytes out of 128 possible with Picaxe8.. 24 bytes left ;)


- So all tricks and everything is actually made in my magic black box, which is esentially an old joystick with an Easy Radio, Picaxe28, LCD, some nots etc.. From that I send all the commands, and so i just press "Fire" on the joystick to make it spin 360, the other button to do another trick, turn a not and make ajustements etc :)


So.. Now little 8 can be controlled by a picaxe28 with an EA on it. Well.. Now another robot is going to be just that, and so another robot will control Little 8 :) .. I think ;)

Shows how far you can get with very few and cheap materials

  • Actuators / output devices: 2 tiny motors
  • Control method: Easy Radio wireless, via joystick
  • CPU: picaxe 8
  • Operating system: Picaxe
  • Power source: 9v battery, 5v regulator
  • Programming language: Picaxe basic

That’s just corny :slight_smile:
A nifty little critter you’ve produced. Although the movie is kind of corny you should use it for promoting the site :-).

If you think “Little 8” is

If you think “Little 8” is small then check this site:

I guess they spent a great deal more money than you did though :wink:

CORNY!!??!!

THAT VIDEO IS NOT CORNY :smiley: (but of course remote controlled things are corny, it is not really a robot imho;)

And yeah, we are implementing "Send link to friend"… maby we should have a competition in here, best letsmakerobots.com-video wins a gift-certificate or something!

Where are your videos, btw? I know you have made some!!

Regarding the Nano-link; Well, as said somewhere else, it was never really the intention of making little 8 small - it was just small components, it really isn´t that small, the circuit could have been 1/6 the size, and batteries another kind, smaller switches etc… But small was really not the goal, just to have fun with a picaxe8 and some cool little motors!

Nice little critter

Really like this little critter, this could possibly fit in side an empty mouse shell, maybe with the mouse functionality intact, which could be realy fun.

Think about it, someone sits down to use your computer and suddenly the mouse starts to move around by it self, that could be fun.

That looks so fun to play
That looks so fun to play with. Small and nervous. Like a mouse on coke :slight_smile: Wish I had some of those radio modules to play with, it seems like that opens up so many possibilities.

YDR+8R=…?
I like it… Wouldn’t it be nice to program the YDM to let the Little 8R ‘dance’ on the beat?

Yes :slight_smile: Well, actually I
Yes :slight_smile: Well, actually I think it should be TIRDNKWIIT that should do the dancing :smiley:

Challenges
I think we should have a who can build the smallest robot challange! =)

Just go ahead and enter the

Just go ahead and enter the challenge, muy friend :slight_smile:

Sounds like a good idea for a challenge!

Challanges
I dont know anything about poasting a challange outher than where to get started.

Have a look at the top-menu

Have a look at the top-menu :slight_smile:

And also on the right, middle, your own menu…

can you please.
Can you please show me the remote of this robot.

hehe great video
hehe great video

Oh, I would love to - but I

Oh, I would love to - but I just don’t have the time to get to it.

OddBot is showing some info on how he made remotes…

I love this guy - so much

I love this guy - so much character :slight_smile:
