Lumpy's - R2-D2 Build Two-Two's

Lol.

The Astromech Droid Emergency Stop Doohickie

It's a simple circuit that triggers a larger relay and disconnects all power to R2's drive motors.

Stops a 200lb droid from running over small children.

Plug in = Droid moves Plug out = All power to wheels off

I'm going to try to re-write the code for it this weekend.

I want one!

btw can this be used to charge the droid? or only to pull power....

Only to switch on/off.

D'oh!

still way cool.

It's a work of art!

This is an UPTOWN build. Very good!

Hey All,

Did some re-work tonight on the "Emergency Stop Doohickie"

Looking back at my 3 scripts that I originally crafted, I now cringe.

This is my safety system to shut down my 200lb droid if it should ever try to make a break for Tatooine. It uses a magnetic plug.

Plug in = Power On Plug out = Power Off (30A relay)

I came up with this new script and it seems to do the trick. Originally I was using greater than / less than parameters but thought this version would use up less processor power?

As always, any comments / tweaks are welcome.

# Emergency Stop System
# MPS Gas Cap
# ADC0  Less than 5 = Power On
# ADC0  Greater than 5 = Power Off

:Loop
$EmergStop=GetADC(adc0)
Set(D0, OFF)
Print("Active")
Say(Emergency Stop System Active)
ADC_Wait_Between(adc0, 6, 250)
  goto(EmergStop)
goto(Loop)

:EmergStop
$EmergStop=GetADC(adc0)
Set(D0, ON)
Print("All Stop")
Say(Emergency Stop)
ADC_Wait_Between(adc0, 0, 5)
Return()

If you don't mined opening up an old post, what are the dimensions of your r2 and is it 1:1 scale?
