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

OK will do!
Absolutely amazing engineering here Dave! What you have achieved is incredible - I cannot wait to see your robot fully assembled with both arms working.
Tony
Thanks Tony. That means a lot coming from a expert builder like you. I'm getting real excited also!
Dave, I don't know what I can say that hasn't already been said. Any words I can think of don't even come close to doing this masterpiece justice. I watch your videos with my mouth hanging open in total awe. Absolutely THE best B9 I have ever seen.

Thanks again Steve. I know that feeling. It's what happens to me when I see your B9 handy work. I'm very jealous of your clean and nicely wired system. How is your build coming along? I often wonder.
well, to the untrained eye, he looks finished, but the arms have only been temporarily fitted in the retracted position so he looks good for a Halloween party we are having this weekend. I recently finished the head section, its fully lit and animated and working well. I have installed the beautiful Fred B. bubble, man was that stressful! I agonized over it and put it off for for days. I was terrified I was going to break it when drilled and tapped it. The bubble lifter is a success, it lifts the fairly heavy head easily. But in saying that, It doesn't come down as well as it goes up. It has a shudder as it goes down. I think it may have something to do with the shaft of the linear actuator has a small amount side to side play in it when its extended and I think this fools the slide potentiometer mounted on the side. I think I will need to Hook it up to the DeScribe software and fiddle around with the settings as you did with your arms, hopefully I just need adjust the Deadband.
I still need to work out how I'm going to mount and articulate the arms. I looked into the IGUS rails and carriages you used to slide the arms in and out on but here in Aus they'll cost me over $500 tired
I also want to do allot more EZ Robot scripting as well but Progress on my B9 has been a little slow of late as we getting ready to knock down and rebuild our house in the new year and we are busy packing and looking for temporary accommodation
Steve
Steve, I'm glad you're making progress even though it's not as much as you would like. I know that feeling.
As far as the shudder while lowering the bubble; I've seen this with my radar swinging back and forth when I enable the ramping feature. I know I have nothing that would make it hang. By hand it moves smoothly. I am pretty sure the issue is the cheap multiple turn pot I'm using. I think it might have a lot of electronic noise as it moves and is screwing with the Kangaroo's commands as it tries to control the radar motor. This may be the same issue with your linear pot. My plan is to replace that cheap pot with a high resolution encoder and retune the Roo to use it. I've had great success useing encoders with the Kangaroo. This may seem like overkill but there's nothing better than to watch a smooth and well controlled radar rotate back and forth with a nice ramp effect.
Do you want me to see if I can buy the IGUS rail and carriage system for you here in the USA and then ship them to you any cheaper? I know I spent a lot of money on mine so they aren't cheap any way you go. However they are machined in Germany and are a super high quality.
Good luck moving into the new crib and getting the old one out of your life.
@Dave Schulpius
I love your last Video! Really exiting Machine! only this part of robot looks like a deep sea robot haha
You work so cleanly and properly! Perfect, man!
