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

Wow that works really well! Congrats man!

I put my rubber sleeve on to make sure it still works. Pretty good I think.

Now to make a second arm and finish the bondo on the arm sockets. Getting close now!

sweet!

Thanks! I think it looks more fluid than mechanical - which is what I was going for. My servos are metal gear so the whole set up is fairly strong for the small size.

There is "tool dip" rubber spray that would be great for making your flex tubing look like black rubber. You could spray it on the black plastic for the legs to also make them look like rubber , then it would all match!

#222  

Those arm covers are actually black rubber - it is the hose from a gas mask. But I like the idea on the legs.

#223  

Finally back to work on B9 - Got my arm sockets blended in and sanded. Ready to prime and sand some more.

And here is a video of the arm in the socket. It moves pretty well...

Brett! That's awesome on the arm. What kind of servos are you going to use for turning the arm? Are the claws going to open and close or you just going to leave them stationary. Most the time they didn't open and close in the tv show anyways.:) I didn't realize how big your bot is till you have a chunk of the torso in your hand , those two holes on the front of the torso.... Do they have a purpose? Maybe make them "headlights" ?
