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.

Very nice!!! An Aluminum build looks sooo much better than a styrene build and pricey too. Do u have a shop to do the metal work?
First page updated with links for info and parts. Please note there are no complete kits available for purchase. The groups are there to help support, guide and assist in your R2 build.
Do you mind me asking how much you paid for all your parts, since you went all aluminum. I am building an all animatronic B9 robot from Lost in Space. I've probably have about 12 grand in it so far, 5 years building and still not done! They certainly are labor of love. But R2 is my next robot for sure.

Wow 12 grand ........... eek
WOW I always love seeing really well made R2s! I wonder what you have to do to legally get paid for appearances to get some money back for the build. Amazing build!!
I stopped keeping track at around $16k.
George Lucas sometimes contacts the R2 builders group for paid gigs (Movie events, PC Game events, Commercials).
In general the group members don't charge for profit. They will take money for compensation for gas/travel but anything else is typically donated to a charity.
All I can say after looking at this is "Holy Crap!" What an amazing build. I wish I had the time, patience, money, skill, etc. to do this. It's really an awesome piece of work. I hope I'll run into you and R2 at a show someday.
Impressive quality! Your robot could really make a trip into space without being damaged
