Hello Again,

I've been asked to post some pics of my R2 build. I'll toss them
up. This has been approx. a 3 year project for me. I chose to go
the 100% aluminum route with my R2. Purely a personal choice.
I've had many revisions to my build over the years.

I look forward to retro-fitting R2 over to the EZ-B system. I'll be
mounting the camera in his Radar eye, and the Sonar around his
skirt area.

Basic overview:

Frame - Com8 Ver. A
Dome - Darren M. 300mm
Legs - JAG
Foot Shells - JAG
Leg Ankles - TotallyWired
Center Ankle - JAG
Holos - David Shaw
Front & Rear Logic Surrounds -David Shaw
Radar Eye - David Shaw
Power Couplers - David Shaw
Octogon Ports - David Shaw
LDP - David Shaw
JEDI Control - Scott Grey
Skins - John Sherrel
And probably a schwack more stuff I can't remember. ;)

Future Updates - EZ-B Retrofit

The Goods:
(1) EZ-B Kit

The Inventory:

(1) Sabertooth 2x25 - Motor Controller
(1) SyRen 10 - Motor Controller
(1) Pitman Motor - Dome Rotation
(2) NPC (Clone/Surplus) - Foot Motors
(1) Xbox 360 Controller

On Order/Inbound
(1) XBOX 360 USB Gaming Receiver
(1) Sparkfun MP3 Trigger Board

The Plan

Drive - Hook up the two motors for H-Bridge control/steering.
Dome - Hook up the one motoer for dome rotation. Link to Camera for facial tracking.
Sonar - Hook up to bottom of skirt for collision avoidance.
Control - Use XBOX 360 controller to drive and control sound. (Android Tablet to replace?)
Audio - Sparkfun MP3 trigger to play audio. Initiated via voice recognition.

That's the plan. I'll probably blow something up first. :D

Always looking for help and suggestions.

Some more upgrades for R2 while he's down for maint. Every droid needs
carbon fiber dome pie panels!

Why?... Because...

the magnetic power doohickie!

details please!

#25  
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.
#26  
I want one!

btw can this be used to charge the droid? or only to pull power....
Canada
#27  
Only to switch on/off.

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. :D

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.

Code:

# 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?
Canada
#33  
No worries,

It's 1:1 built from R2 Builders club specs.

I'd have to dig up the exact measurements.

Any particular dimension you after?
#34  
legs and feet.
Body is 34" right?(not counting legs)
Dome is 9"?
#35  
Great build Lumpy! I am so happy to be apart of this forum and !all! the brilliant craftspeople, also thanks to Technopro for floating Lumpys project to be "rediscovered"

Hi Lumpy,

I too am a member of Astromech:) My droid is coming along pretty well ( its a hybrid build) I am getting to the point of integrating the EZ-B into him... I plan on leaving the dome lights independent to the teences thing... I want to go ez-b for drive and everything else... with override to manual control of course... You have any updates of how you have integrated the ez-robot into your R2?

Hey Jayutmb I am building a droid as well on Astromech!

Where about in the US are you located? I am located in Southern California... I plan to be at R2LA next weekend with my shell of a droid lol How far along is your droid?

Hey Guys,

I'm still kicking about. I didn't get too much done this summer. My wife's father
passed away and then my mom passed away 1 month later. So it's been a
tough summer to stay focused.

My E-Z B's (I have 1 in body, 1 in Dome) are hooked up to the following:

- Sabertooth 2x25 (Foot Drive)
- Syren 10 w/Kangaroo2 (Dome drive)
- Relay (Dome PSI Lights)
- Relay (Periscope Power)
- Relay (Misc)
- Periscope Lights (Switches Modes/Sequences)
- Sparkfun MP3 Player
- MPS Magnetic Switch (Emergency Shutdown)
- (2) Sound activated sensors (Autonomous Dome Movement)

I haven't had much time to re-script to my new V4's but hoping to get that
done during the winter. The new wifi capabilities are what I like. Picking up
my V4 camera this weekend and will be getting that mounted in the dome
shortly.

Robot56 enjoy R2LA. Say hi to Mike and the boys for me. I may try to pop
onto the live cam feed again this year.

If you guys have any questions feel free to drop a post in here. I'll try my best
to get back to you asap.
#39  
Thx for response Lumpy:) and @robot56 I am done with my dome ( the outside of it anyhow ) the lights are working as well.. body is skinned and i am in the prime and sand phase right now. Legs primed but missing a few things still. I will just toss a pic here it speaks for itself ... ( legs and hubs are not really connected with why it looks so loose )

One thing I am trying with mine is not using paint for things... example the brushed blue aluminum look in pic is 3M auto wrap.. I am still up in the air if all the white parts will be done with wrap as well... or just paint it... ( I kinda wanna have my own "thing")

gratz on going R2LA as well! I am in Houston Tx... so that is a bit far for me and my wife would kill me if I left to do anything "droid" related lol

Very cool build.
I am a R2 builder also, but all of my EZ-Bs are in my humanoid robots.
R2 will be getting one in the future.
I hope R2 gets to do tons of cool things in the up coming Star Wars movies.
