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

I closed up the drive section and put my leg section in place. It's starting to look like B9!!!!

@jstarne1 - Thanks man! Hey, go to All Electronics on line. I believe they have the motors you need for your arms.

#82  

WOW!! that's looking really great Bret .:)

#83  

Thanks! I started wiring up the motor controller - one of the original units DJ sold (BV4113 ) it is rated at 1.5 amps. I hope that is enough to run the drive motors on the RAD with all the weight I'm adding (about 10 lbs). Maybe with a big heat sink and fan it will be okay.

#84  

Yes , glue a VGA heatsink to the chip and put the VGA fan on it.I gave you

#85  

Picked up some thermal compound tonight. Already had a heat sink. And I was planning on using that fan - thanks!

#86  

Ive tested those fans up to 12 volts, ill try getting the sound deadening Matt out Mon. Is there anything you need or looking for right now?

#87  

Hey Josh, thanks a million man. Can't think of anything at the moment. I will have my motor controller done shortly then on to the torso rotation. Is there anything you are needing? I have an extra one of those aluminum claws I used on my omnibot if you want it? A couple of micro servos too. Just let me know.

After reading this post linky I seriously wonder if this motor controller is going to work for me, or I need a larger one?
