Next Hack - Robot B9

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

Nice, we need pictures!

Speaking of pictures, here are my final pics of B9 for this thread. Got all my stuff plugged into the EZ-B.

Close the door and it looks good.

Now he is all buttoned up and ready for programming.

I took a video but don't know what happened to the sound. I turned him on and his chest lights come on, and the green light on the lower right is his battery charge level monitor. The one arm needs a little repair as I messed up one of the elbow servos (broke the servo horn mounting screw off in the servo.

Cool thats awesome! Are those leds directly controlled by ezb?

#531  

Nah, it's a flasher circuit drawing right from the step down buck converter. Comes on when I turn him on. Very little current draw.

#532  

Well it looks cool , was it a kit? Linky?

#533  

Yeah, it's a sequential flasher kit and I doubled the LEDs per output. Then mounted them randomly in my holes.

So I have all of my connections sorted out and have some movement.

Working on all of the controls in ARC, then I can start on some real programming.

Of course I still need to fix his one bum arm....

I dont understand how your using radar ping on you ultrasonic but your ultrasonic doesn't move? Can you explain how your doing this?

#536  

The radar still scans via programming, even when stationary (it is really just the sampling rate but looks cool). The servo just expands on that scanning distance/field of view.

I started working on some of the programming (even though I have to get a few things fixed). At the start of this video look closely at the antenna and you will see random movement.
