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

Hi Dave,
My condolences on the loss of your friend. I'm so sorry to hear that, but at least she got to see him completed waving his arms about.
Your B9 is nothing short of incredible, truly a work of art. You have set the bar so high only the most talented few could ever reach it.
Amazing work my friend
Steve
Dave ,
As always, a Great Job. It was fun to see the classic Danger, Danger, and the other features ! Will Robinson would be proud.
Time, work and effort spent shows thru his animations. Thanks for sharing your work.
Sorry for your loss. Rita sounds like a special lady. I know she will be missed.

Dave, Wow! your B9 movements are so smooth the arms are now so realistic! The mechanics behind this are incredible, your dedication to this robot project is a shining light to all of us. I always look forward to your videos showing this great robots build and evolution.
So sorry to hear about your friend Rita, it sounds like she was one really special lady.

Thanks for the kind mention to my work and the comforting words about my loss. Although I am sad at Rita's passing I truly meant that video as a happy tribute to my friend. It was really for Rita, her friends and family. I felt I'd like to share it with you all here also for obvious reasons. I smile when I think of her.
I modified the arm wave movements so they aren't so large. After watching a few episodes of Lost in Space I noticed that Bob May (the actor inside the robot) didn't swing his arms all the way up to the collar and down below the hips. He just moved is arms about about 1/2 of the total arc. This may be different in other episodes. After adjusting and limiting the swing I really liked the animation as it seem more familiar to me. However an odd effect took place; even though I had raised the motor and servo speeds to their max the moment speed seemed slower. Probably because of the shorter distance the arms are now traveling on the arc. It's amazing to me what the human eye will see and how our brain interprets it.
Hi Dave,
I know you WILL NOT mess with the current settings ! But the PID loop may limit top speed by using a different calculated curve during accel and decal during the total arc. Just a possible explanation?
Works perfect in my eyes.
Ron
"oh boy... okay"
lol best ending ever
@Dave Ha, Ha... guess your next project is the Jupiter 2....
How many ezb's for that?
@Andy, LOL my friend. I truly respect your skills but I understood very little of how to do what you just suggested. I tried to learn PID control adjustments and put many hours into the effort. In the end I turned to what I understand is the method most operators end up using, "trial and error". By resetting the different co-efficient settings It took many, many hours to get these arms to operate as smoothly as these do. Even so, I still have some glitches when the speed is slowed down on a downward swing on the left arm. However, I do have some acceleration limiting built into the settings to help with a ramping effect.
Thanks for this suggestion. though. It sounds like you have good experience in setting PID co-efficient settings. I would be honored if you could stop by my place and lend a hand if you're ever in Waukesha, WI. Heck, I'd even buy you a couple beers (after the work was done. LOL).
RR, It would be so cool to build a J2 in the backyard. I know a couple people that have done this. Really! The're so close to the real ship from the TV show that it's chilling. I figure it would take at least five EZB's to operate a J2. Maybe another two if you want it to break orbit and head out into deep space.
