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

Are you still getting a slight glow from your LED's when he's powered up? I do know that some regular LED's have a problem with "Ghosting". It's been a problem for the pinball guys who are upgrading their games from the old incandescent bulbs to LED's. Cointaker.com sells a large selection of NON-GHOSTING, Non-Polarized LED's. These LEDs are specially made to prevent LED from lighting when turned off. Also Engineered reduce Strobing Effect. Look here: http://shop.cointaker.com/category.sc?categoryId=184 Here's a link to a video one of my friends made about this ghosting problem on a pinball machine. Seems they found a way to fix this problem through the software ROM in the game. Don't know if the fix will help you here but the visual is great and nicely shows this problem: http://vimeo.com/12823973

Good luck and have fun! Dave Schulpius

Bret.tallent Thanks for the link! much cheaper than Sparkfun trigger, and I think with 40 reproductions enough.

Soon this guy will be running around the house. Have you installed a charging jack in the back yet? Its somthing I overlooked lol

Oh yeah! That was one of the first things I did. lol It's in the RAD base on the back.

Yes, he needs power to live! Once we get AI running in these guys they will be like friends and not just robotic toys. Who knows how smart they can become. Good programming can make them so much more alive now that the robots can hear and see. Measure distance and even scan the room with sonar. A blind robot bumping into walls is all in the past. Yes, robots still bump sometimes, but so do we. I so much want to see your robot running across the floor talking and waving his arms. He need a tilt switch so he yells danger when he falls or comes close to falling.
