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!

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

You could try the ESCs like I'm using ESC 20A I know they are listed in euros but they are coming from china and shouldn't be a problem. I have the pdf for these if you want a little more info.:)

I decided to leave the drive section alone for now and work on the torso and "head". I decided to put the camera in the collar and rotate that separate from the torso. First I had to cut the upper "head section" away from the shoulders

Then modify the collar and neck to house the camera.

I will use a lazy susan bearing to join the head back to the shoulders. The camera fits very well in the collar with just a little modification.

Placement looks good on the camera.

I wanted to have the antenna move like the original so I modified the collar top and a couple of micro servos - then painted it all up

Not exact, but good enough for government work...

Now I can rotate the antenna just like his big brother.

Good job on all the parts Bret !:)

Your B9 is coming along very nicely.

Thank you! I saw a B9 like mine on ebay today going for 40 bucks, still a couple of days left but....

Here is the lazy susan bearing mounted in the top piece ready to accept the head.

And here is the head section with the camera, antennae, and bubble with lights. If you look close you can see some fiber optics coming out of the bottom. Next to mount this to the top section and test out the camera, head movement/tracking, and lights.
