Omnibot Hack Begun

Inspired by DJ and so many of you out there, I have finally begun my omnibot hack. While awaiting the arrival of my EZ-Board and camera I have disassembled, washed, and painted the little guy. For making mods to the body (ie. the head to rotate and the arms for servos) I found that I had much more control by putting my dremel bits in the drill press on high speed than I did using the dremel. Shaky hands haha. I have decided to make one arm completely controlled right down to an articulated claw, while the other will simply move at the shoulder. I hope to take some pics tonight to upload (as soon as my camera's battery charges haha). Then I know I will be bugging you all for help with the programming (definitely my weak area).

Upgrade to ARC Pro

Harnessing the power of ARC Pro, your robot can be more than just a simple automated machine.


Ahh I had my omnibot ( Dobby ) in bath today :) And tomorrow I will order the electronics for Dobby. He needs a brain, some movements for every joint and hands.

Building is fun but the programming is also fun:)

HAve a lot of fun !!!


Sweet! It's an omnibot and wall-e party. I think we're making omnibots popular again:D


Hi DJ, I am also doing the omnibot hack and I am having some problems I hope someone can help me. The servo for the arms and the head are working great. However I am having problems with the eyes. I would like to be able turn each eye on and off or change the color of the eyes. I have tried to make them a digital but that did not work. I have also tried to use them as servo's that did not work. I am following the instructions but I can't get it to work they light up but I cannot turn them off

The second question is I have a 6v battery for the omnibot how can I connect it to the ez-robot and still be able to charge it.

I thank that EZ-Robot is the best thing ever. I am loving it.

Thanks BC :)

The LED eyes in my Omnibot are hyperbright ones but any LED will work. You use the outside wires of a servo lead not the middle lead cut that out and use the set digital command on the EZ-B or to vary the brightness you can use an analog port I expect you know LEDS only work one way round but you won't damage anything if you get it wrong. I have fixed colour LED's to change colour you would need to use something like the BlinkM device and the I2C bus. I connect my battery via a kill switch to the EZ-Board then to the socket on the back of the Omnibot. The charger plugs straight into the socket and it will charge the battery and run the EZ-B Board at the same time if you want or you can switch it off and it just charges.

I will see if I can post a diagram or pic tomorrow for you


Thanks winstn60 for your help I will check back latter to see if you have posted any thing.
