Hello Everyone!

I posted a project a while back, (2014 so a wayyyyy while back) about a robot I was building that at the time I was calling J.A.R.V.I.S 
Well, shortly after I posted about that, Amazon released the Echo, I experienced a layoff cutting into my budget and then I returned to college full time to finish my degree. Needless to say, J.A.R.V.I.S was shelved and I went dormant for an extended period. That said, much has changed and I'm finally getting back into AI and robot building. I've re-purposed the parts intended for J.A.R.V.I.S and am now midway through development on my new bot, Artemis. 

Artemis is built on a Max '99 robotics platform from Zagros Robotics, two 12v motors on the wheels connecting to an H-bridge going to the EZB-V4 and a mannequin torso, with two servos in the neck for pan and tilt. Need to upgrade the battery as 6 rechargeable AA's is no longer sufficient for more than a few minutes. Have arms currently printing on my 3D printer (C3PO replicas that will take about four days to print). Originally had a small usb monitor mounted on the back that was going to connect to an on-board PC but, thanks to almost 5 years of technological advancements I'll be replacing that with an android tablet running EZ-builder. Will also be adding a camera for object tracking and facial recognition as well as multiple ultrasonic sensors for obstacle avoidance. Been planning for a long time but just finally started building this past weekend so there is much much more to come!

I like Your Robot, it will be interesting to see the C3PO arms, are the arms already designed for servos or do you have to design joints and add servos, will this robot be automonous and what function is it designed for?

Great robot project! It is always fun to see the other Giant robots out there, the more the merrier I always say!

Fantastic!!  I have often thought about getting a base from Zagros Robotics but I'm not known anyone to actually have one.  Are you happy with yours?  It looks nice.  Did you purchase their H-Bridge to go with it, or get your own?

The C3-P0 arms are from thingiverse and meant as part of a cosplay outfit.
the forearm and bicep are designed to be hinged but I’ll be creating my own servo mounts. Have the right forearm printed and the bicep printing now. Using a monoprice MP10 printer (300mm x 300mm x 400mm), with Hatchbox PLA. Really great prints so far!

i plan on it being autonomous and to operate as a security bot / service bot for simple tasks. Like getting drinks, greeting guests, answering questions, etc.  

as for his base and H-Bridge, I’m very happy with the Max 99. There’s a gear upgrade available on their site that increases speed but t was unavailable when I placed my order. That said, their standard 12v motors are more than sufficient. If you do order one or their platforms, and want a taller bot, go for the extra level kit. It’s worth it in my opinion. for the H-Bridge I didn’t utilize either of the ones available via Zagros or EZ-Robot. Picked up an aftermarket H-Bridge from IO from Microcenter. Along with wire extensions, pin headers, solder, etc.

pics below are of the printed forearm, printing bicep, and h-bridge:

Update on Artemis. He’s recieved a paint job and is getting a head transplant. Going from an omnibot 2000 head to a Wowwee Elvis head. For those that have worked with th Elvis, would an h-bridge be sufficient to interface the mouth motor with the EZ-B? Or should I just swap it out for a servo? 
Pics are of current progression. Going to be cutting down the torso to implement the new head. Arms have been put on delay since the new head unit has its own shoulders.

Nice to see you are making progress on your project!!
Keep going!! It turning out great!!:D

I know it's just a hat but I love it! Never thought I'd see Elvas in a tophat. 

A H-Bridge will work but it's not as easy to setup and control as a servo in ARC.

Thanks Dave. Thinking I may just swap out the jaw DC motor for a digital servo for simplicity. Here’s a video of where he’s at. Still using the default Elvis scripts. Mainly testing movement and balance. Got the head mounted. Just need to mod the jaw, re-route the audio, and wire the jaw servo and the heads speakers to the EZ-B. Going to be mounting his arms finally too since the head has its own shoulders they can mount to.
