Hi all,
I'd like to share a video I just took of my full size Lost in Space B9 robot that's controlled by two EZ-B controller boards. Right now they are controlling limited movement and voice response of a few motors, lights and sound files played from a Sparkfun MP3 Trigger board. Although I'm just starting with the animation and have more building on the actual robot the result (mostly thanks to the EZ Robot controller board) is shocking. Please have a look at this (4 minute) You Tube vid and enjoy.
Please excuse some Technical camera lighting and sound issues. This is the first time I'd made and posted a vid online.
EDIT 8/2/13: Just realized I have no good pictures of how my B9 will look when complete. Here's one of the actual TV robots from the 60's TZ show Lost in Space and one recent shot of where I'm at with my build over 1 1/2 year after I started. Enjoy:
Thanks, Dave Schulpius

@Dave.
I've been following your B 9's build for a while now, and realised I haven't posted a comment yet.
I have to say everything that you have done so far is truly outstanding. Your attention to detail, design and materials used with what you have built already really is amazing. And thanks for sharing your work so far via the videos you have posted. You really get to see the amount of work that has gone in to this. I gave yourself and your B 9 a little mention in a video poem I posted. Don't know if you have seen it yet.
By the way, long videos showing content like this is really not a bad thing. Watching your latest arm videos has given me a couple of ideas for my next build, so thanks for that. So keep up the great, and inspirational work, and I tip my hat to you sir. Wonderful stuff.

Dave that arm is the best I have seen so far. You are setting the course for all future B9 builders. Outstanding work! Can't wait to see the extend retract in action.
Dave,
I think my wife WAS impressed this time with the skin off. She said "He must be an engineer or something". Also, this time she wasn't asleep when I showed her
As for my opinion, what a beautiful piece of engineering! You have done an incredible job designing and building this beautifully elegant and fluid arm. Its a masterpiece. I have been following your B9 progress for a couple of years now and you never fail to impress and inspire me and this time is no exception. The whole project is a work of art, your attention to detail and build quality is mind blowing. you must be very proud of him.

Hey guys, thanks for the kudos. It means a lot to hear you all have enjoyed my work. I am very proud of how he's turning out. It's been a ton of work but a labor of love. There's lots more work to go. After I do some scripting to smooth out the arm DC motor by doing a few mods on Rich's ramping script.
@Warpig, The wrists are Craig's light weight set he just started selling a few months ago. The claws and centers are taken from a set of Bill K's claws and wrists. By substituting Craig's wrists for Bill's I saved a full pound.
@Steve, I just watched your poem. What fun! Thanks for the mention and the entertainment. I loved it. That had to take a lot of work and talent.
Hi Dave;
Outstanding mech. Great video's thanks for sharing. I just finished the assembly ans calibration of my Printbot 3D printer. It's up and running and alot of fun, just amazing to watch. Next up - Green Bay vs SeaHawks - Go Pack!

WOW! That is an unbelievable piece of engineering !
thanks again guys. My next part of Project is getting this arm to move smoother. I'll be working on learning and trying out different scripts to see what I will be meeting to do that.
Here's an update on my B9 Robot's arm build.
The whine that the HS-7950TH digital servo was making while holding a load was driving me nuts. Then a mishap happened. I got the servo hung up on something while trying to adjust it and didn't know till it was too late. The result was that it's circuit board burnt up. $150 of magic smoke. Luckily I had been trying to get up the courage to pull out the control board and replace it with a Pololu jrk 12v12 motor controller and this gave me the excuse to do it. The Pololu jrk 12v12 motor controller has ultrasonic switching and the result is a very quiet digital servo with no whine. It worked great and is now very quiet.
It's very easy to do: Remove the old circuit board from the servo and cut the control/power cable and the wires going to the potentiometer off it. Extend the wires from the potentiometer and solder new wires to the motor and connect them in the proper places to the Pololu jrk 12v12 motor controller per the instructions. Set up the Pololu motor controller through a USB connection to your computer with the provided software. You'll want to place the controller in Hobby radio control (RC) pulse width mode to use it with servo controls in ARC.
It's all really quite easy to hookup and setup the motor controller and easy step with the step by step instructions.
Here's a link to the servo:

Here's a video and some pictures of the process:
EDIT: in this video I say that the servo gets hot and should not be run continuously. Turns out that when I burnt out my servo circuit board I also damaged the motor in it. It way pulling 3 times the amps or more when it moved and causing tons of heat. After placing a new servo in the gearbox and replacing the circuit board with the Pololu jrk 12v12 motor controller there's hardly any heat buildup when run for extended times or if holding load. When the servo is moving at its top speed and lifting this 3 lb load it's max amp draw is 1.7 amps and when holding this load it's a steady .3 amps!
