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

Here's the second animation I've created for my B9 Robot from Lost in space now that I've got both his arms mounted and working pretty good. This one is more involved and takes advantage of most of his moving parts excluding his hips. I'm really putting ARC through a workout here. There's a couple bugs to work out yet but I think things are looking pretty good. Enjoy.
Cool work! Love the life you are putting into your B9 robot.
-Thanks SOOO Much ! At last I got to see what I have waited for. A great job....
Looking forward to more videos.
Have fun and thanks for sharing the construction journey, and now the bring of life to B9.

That's great, Dave! Can't wait to see what you have next.
Cut from my YouTube post. Even though It's directed at my friends over on the B9 Robot Builders club forum I thought it would be of interest here also :
We were having a few discussions on the B9 Robot Builders forum about reducing motor noise and also adjusting the brightness of LEDs. Afterwards a couple very smart and qualified members (Davis M. & Robert R.) contacted me privately to discuss their thoughts. They both suggested that the best way to accomplish both was to adjust the PWM (pulse width modulation) being sent to the motor or LED. This method still offers full voltage to the LED or motor but sends measured "bursts" of the full voltage. I gave it a try and filmed the process using EZ Robot' ARC platform to assist in adjusting my PWM to noisy motors. This method didn't silence my motors but after finding the "Sweet Spot" I found that I was able to reduce almost 3/4th of my motor noise. Thanks Dave & Robert for getting me to think this one through!
Interesting. I use PWM for controlling apparent LED brightness (comment below). Never thought about it for non servo motors.
(comment: the reason I say apparent brightness, is if you video the LED while it's brightness is reduced via pwm, you can see it is actually full brightness but flashing. Due to persistence of vision, you see it as dimmer. This is important if driving a laser rather than an LED and think that reducing the brightness via pwm makes it safe to look at. It doesn't)

Hi guys,
Please forgive any sadness attached to this post. I don't mean this as anything else but a joyful dedication to a friend I lost yesterday. It has always amazed me how many ordinary, regular people really love Lost in Space and robots. Almost to a one when the subject is brought up they first mention the robot and his Danger, Danger, Will Robinson with arms waving routine. Rita was one of these and she was so excited when she found out I was building a B9. All she talked about was how wonderful he was and how she couldn't wait to see this arms waving routine. Well, I was fortunate enough to finish the animation a few weeks ago and share it with her. True to her personality she was full of praise, amused and happy. However she said; "He didn't say anything about Will Robinson". Well, today I was inspired to add that little saying and improve this animation routine. I've smoothed out the movements and added a few small things that no one but me may notice.
Along with the improved Danger, Danger, I also show a new animation I've been working one and new Date, Time, and Temperature scripts that are integrated directly into ARC. This new smooth feature is thanks to our fellow builder David B who was watching the old way I was doing it and cringed. LOL. This great guy sat down and spent hours of his precious time writing scripts and categorizing sound files from Craig's I-B9 CD to make this work. Thanks David B! The first time my wife heard this she said "I thought that guy was dead? How is this possible?" LOL
Enjoy and God bless my muse, Rita.

I know you guys love Bloopers. Who doesn't? I was trying to show off a few new arm animations and things weren't going very smooth. I hope this puts a smile on your face:
Enjoy, Dave Schulpius
