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

@Tony, your offer to help with the Kangaroo ramping script for the EZ Script is comforting. It's good to know we have a pro like you willing to help us on this.
I hope you get your V4 soon. I'm really interested (and a little anxious) to see how this script will look.
I've been bugging DE about this issue and finally got back a reply. I was asking if there is any way to get ramping to work in Position Mode and a clue on how to do it. They said no, but.........
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> We do not have a combined position velocity and speed command. However there are ways you can achieve this.
You can send a combined accelerated velocity command until you get up to speed. When you are up to speed you can send a combined position velocity command and it will keep tracking at that velocity.
You could also write a loop to slow down. It would manually step the speed down as you get closer based upon position.
Also you could go into the control tab in the DEScribe software and reduce the system gains so it doesn't accelerate and decelerate. This would be in Control/advanced. Have the position gain double the position reset time and that will make it respond more gently.
We do have plans for these in the next firmware revision but that won't be out until summer/fall. <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<,
So there ya have it. Looks like the fix for native speed ramping will come directly from DE by the end of the year. In the mean time Tony, the script your offering will be truly needed and welcomed.
@Bret, Here's the schematic you were asking for. This will allow you to use the EZB V3 (or V4) and if you have a problem and end up with a run away or overshoot the limit switches will cut power when triggered. The diodes installed will allow you to back the motor off the limit switch even though the power is switched off. Ya gotta love DC voltage!
When buying the parts make sure you get components rated for the amps and voltage your pulling. If you need help locating parts of anything else I can assist with please ask and I'll give a hand. Hope this helps:
EDIT, Added 5+vdc between EZB & H-Bridge,
@Tony.... I would appreciate the script too... thanks @Glen... I am just a really early riser...
Dave, you are awesome! Thank you
No problem Bret, Let me know if I can help any more.
Love your B-9, he looks fantastic! You have put a lot of work into him. What's this R2 thing he has?
he he he 
Just had to put that in. 
I'm not sure what is with that. He just keeps saying, "R2D2, what a hack!". I think he's just jealous
I think R2 is jealous of him, R2 is a bit smaller!
This is so cool! He has a great sense of humour
