Ok, I can now 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 ;)
