Hey everybody, its been awhile since I built a bot, and I'm back to humanoids again lol. This is a cheap 15 DOF robot kit that I found on ebay. All the kit included was powdercoated aluminum brackets, screws, and those awesome aluminum servo horns. No instructions. So, I kinda built it my own way, with a layout similar to JD. I used MG995 servos because theyre cheap, metal geared, and (supposedly) 208 oz/in of torque. only the head servo gets its power from the EZ-B, all the rest get power from a Castle Creations 10 amp regulator. It's not enough. From what I read, these servos draw 2 amps each...gonna add more regulators later. Ok, enough chit chat, watch the video and lookit the pics!

Hi there, my name is Tez, I have just completed EZ-Robotifying my G15 KS. Not a technical term but sounds good anyway....
Gwen4156's G-Bot Video
Finally had a chance to look at some video from Halloween. Here is a brief video of the G-Bot in action. Thanks so much...
Nice. You wouldn't happen to have the ebay link would you? Rumor has it that I'm getting Roli for Xmas but I'd like to check this kit out as well.
Theres a few different kits, just search "dof robot" on ebay, theres a 9, 12, 15 and 17 dof versions.They come with all the hardware, no servos. Mg995 servos cost $30 for a set of four, whis is a great deal considering standard futaba s3003's usually cost $10 each and are only 42 oz/in of torque instead of the 208 that you get from the mg995's. Its all shipped from china though, shipping is usually frew, just expect it to take like 2 weeks or so to get to you. Totally worth it:)
At the current time we only have plans to produce the EZ-Robots in white, but who knows what the future will hold! Its certainly not tough to change the color of the plastics....
In the meantime, if you find someone with a 3D printer (or eBay/UPS etc) it would be easy to have one printed yourself. Or even the quick and dirty route of dyeing or painting it yourself!
Thanks Mark:) Its kinda funny, I found a temporary head for him, and its white lol:) I also added two 96x64 pixel oled displays. And some new moves.
wow those eyes are amazing! how was it integrating them into the ezb?
Not bad at all. They each have their own processor and accept serial commands from the ezb's d16 and d17. it accepts two byte hex commands like "SendSerial(d16,9600,0x55) to initialize it. there's a whole list of commands to draw shapes and load pictures and stuff. What you saw in that video was a preloaded program installed on each chip that runs as soon as you give them power. I wrote some scripts for drawing eye dots and such, and they work. but often times, using sendserial commands jerks all the servos at once causing a brownout. It's the only time that happens. not quite sure how to fix that...
Thanks for the tip Kenny
Do you mind me asking, Jeepers Creepers, where did you get those Peepers?
Boom, there it is, somebody had to say it lol. The eyes are 4d systems uoled-96-g1 sgc displays, which are discontinued lol. They have new versions that work better, and they only cost about $40 each. Spend the extra money and get their programming cable, you'll probably end up having to reflash them at some point. They need to be turned on and off at specific times during flashing, and their cable supports that, its hard to build a cable with that feature. They also handle up to a 2gig micro sd card for storing and recalling pictures and videos. Google 4d systems, they got all kinds of displays and shields lol
