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

Thanks Moviemaker, let me know if you need any tips on your build. I will look thru my parts and see what I have left over from the build. On the neck, I just extended it as far as it would go and screwed it in place.

@Robotmaker - That's a lot more money buying through that eBay auction ($179.00!) then buying directly. If bought through Allied Electronics you'll pay about $70.

I really don't want to hijack Bret's topic here (Sorry Brett). If your really going to build one of these big B9's I suggest you join the B9 Builder's Club (it's free now). We have a web site (through the above links) and a e-mail group with lots of help. We can continue this discussion there.

Where did you get your standoffs? and what where they called?

Can you please share to patterns, especially for the hands? I don't have a 3D printer, so I need a 2D drawing that I can print out and cut out.

Thanks!

@Fred I got the 24" B9. It's neck mechanism was broken. But it did not damage the main parts. Bret was right, the drive mechanism sucks. So, now I need the drive from the RAD. I had a RAD in my hands a few weeks ago that I could've gotten for $4.99. But, I said "no, I want the Omnibot" So i passed up possibly that comes one in a lifetime.

Doh! I hate it when I do stuff like that Moviemaker! Don't feel too bad. I've found that "once in a lifetime" deals usually come around again sooner or later unless your lifetime is very short.

GREAT job! Where did you get the mini servos ?

#551  

I would like to say Thanks for pictures and videos. Plus all your time explaining how and why you did this and that. I read it from start to finish, all 551 posts. All I can say is five stars out of five stars.

Thanks Guys! I got the mini servos on ebay. The claws I just cut out of some ABS plastic. I can try to re-draw the design for you.
