Now that I have finished B.O.B., my get your feet wet bot, I have begun my next hack. This next robot will bridge the gap between Bob and my ultimate big robot. I am starting with a remote controlled B9 toy from Trendmasters. It was very limited in what it did, and the drive section was pathetic, but it was B9!
Before Pics:
Note: the front "lights" in the chest plate is actually just a decal.Here is what B9 looks like now:
I have mounted clear LEDs in the appropriate colors in the chest at the bottom of the decal and have a flashing circuit that will blink them in the combination as seen on the series. Where the two large round circles are (white domes on the big guy) I will have my ping sensor. I have mounted pager motors in the antenna housings to turn the "sensors" as seen in the TV version. I have mounted red El Wire to his voice plate to emulate the original as well. I have also mounted a series of blinking LEDs to the "brain" section in the bubble.
Next is to work on the rotation of the bubble and torso, articulate the arms and claws, and make a real functioning tread section. For the tread section I am adapting the base from my RAD robot. I will keep you posted with pics as I proceed.
Thanks,
Bret

Wow. , couldnt have gotten luckier on that one !
Okay, as I started working on the leg section I found I didn't like the silver I had used on the base - it was just a little too harsh. So back to sanding and painting. I ended up using the same silver from my omnibot build. I think it is much more fitting of B9.
In the upper corner is the silver I started with, and the larger image is what I will be going with.

Then I will put a top coat of clear satin finish to protect it and take some of that gloss off.I think that will look a lot better. I always forget satin finishes for some reason? Had to do my kitchen cabinets twice to get them looking right. Gloss first time satin second time and looks good . That really is a better silver Bret !

Thanks, I think so too.
Yea the gunmetal color looks much better. How are you going to make him twist?
You could put a wheel on a servo , and make a lip/ ring and glue it inside the body. Mount the servo and wheel agianst the ring and that can control left and right motion and no gears to strip incase it runs into a table or falls over , just center it back and keep going. Much like in the pic the tire is agianst the ring on this carnival machine. No belts to break no gears to strip.....

You can snug the wheel on any edge , top , bottom , or like I have pictured on the insideThanks Josh - The inside of the torso base already has a 1/2" lip in it all the way around so that could work. Also, ALL of my high torque servos are metal gear so that will work too. And in the leg section there is a nice mounting structure that I could just cut and drop the servo right into. Now I will need to be looking for some of those kit tires that mount to the servo haha.
How do you maintain position of the torso with regard to the servo position in this configuration? Because of wiring I can't have a continuous rotation servo. But a 270 degree servo might be nice.
You probably don't you could use two switches and glue them in where you want rotation to stop. Connect them to two digital ports . The bigger the wheel on your servo the more waist twist you will get per rotation.
