re: cyberjeff
It will be bluetooth from one of the Arduinos to the Phone (instead of USB), and then HTTP requests via Wifi from the phone to the PC. Down the line, I may use XBee outdoors. I have had several lying around way too long. I hope to add one in.
Same PC as with Anna. The server is setup to handle multiple bots simultaneously while supporting separate identity, memories, opinions, and reflex behaviors for each bot. My true love is on the software side, so I plan to get back to that as soon as I can put this bot together. I’d like to experiment with talking to both or getting the robots to talk to each other. I wanted the additional actuators so Ava could be more physically expressive. I am excited about the moving ears I am planning.
Thanks Dickel
Thanks so much Dickel. For those of you that don’t know, Dickel is one of our resident gods that inspire others en masse.
Yes, Ava it is similar to WALL-E, by design, The reason is, my robots are designed to hold a lot of sensors and processors, and I don’t know up-front what I will want to pack into them later.
The square shape will change when i add the new front panel, a 3-D trapeziod like the one in the back. It will hold all the regulators. The result will be a body a little like a duck’s. The logic of the box or the duck shape is to maximize internal space. I may yet cram not one, but 2 Raspberry Pi 2’s inside with 2 more cameras. Space for power supply and wires is the challenge.
I am really looking forward to the cat-like ears, which are really just a concept in my head right now. I picked out the servos…some small 7.4 volt ones from E-Z Robot. I might put a camera or thermal array sensor in each ear. My goal, as always, is to have maximum situational awareness. With scanning ears (with cameras or thermal array), Ava could really have a major improvement in situational awareness, being able to scan 360 degree without even moving the head.
I really hope this translates to Portugeese. Good luck on your projects. I always know that when you are quiet, some new awesome MDI is on the way.

re: Silux
I would like to release AVA’s stl files and code as an open source project. I have no idea yet about how to handle licensing, but that is my goal once I feel like I won’t be doing any major redesign.
I would love to see what you are doing, the earlier the better. My ego made me hold back on Ava for a couple months. I would hate to unduly influence your creativity by releasing my design too early.
I think the question of how to build an endoskeletion or exoskeleton for a bot in this size range is one of the most interesting issues we face. AVA uses a combination of endo and exo-skeleton to get strength. The tradeoffs of design/weight/flexiblity of change is something I lose sleep over constantly. In retrospect, Ava is over-built and as to need, she could lose a few grams. I used 30% infill with the 3D prints. The inner beams (non corner) are entirely questionable. I am thinking about going to 1/16 ABS skin instead of the 1/8 inch skin I am using for almost everything now.
What do you think? Please elaborate. I would love to hear as my conclusions are arrived at in solo.

Martin

USB vs Bluetooth
Hey mtriplett,
You already know I’m following this project :). I wanted to ask you why did you went for bluetooth instead of usb? I’m using usb for now, but maybe there is something I’m not takeing into consideration yet.
Cheers and congratulations for this awesome machine!
