Bipedal Robot for my business mascot.
« on: August 22, 2017, 07:16:17 PM »
Hi I am fairly familiar with industrial robotics and automation as well as CNC Machining so I started a business called CNC Micro and I want to be able to show of my rapid prototyping skills to customers so I came up with a plan to make a fully functional Biped robot and I want everything to move from it ears to its toes and everything in between so I so far have built its head with Galvanized wire and solder. I am currently waiting to order 9g servos for ears eyes and lips as well as make its eyes.

I wanted to know if multiple arduinos can efficiently communicate with one another and receive instruction from an SBC with Linux? Edit I2C and PCA9685 should do the job.

Here is where I am at so far.

Tongue Movement

The Idea is to be as complex as possible and sort of talk like us with mouth movement my original idea was to use a servo to actuate a bellow to simulate breathing and allow air to pass through a loose spring to simulate vocal cords but I scrapped that and went with the small speaker behind its tongue. I also am giving it a dog like head hoping it won't be so creepy aka uncanny valley.
Any one have any suggestions?
Also i would like to add if this works out like I want it to I feel it would be a cool open source robotics kit for anyone.

Small update I took a good part of the day making its shoulders and a part of its chest hoping I can find solder able servo horns for large scale that would make life easier for the shoulders simple linkages made from the galvanized wire won't be strong enough to lift the arms.






Here is another short video.

There is obviously a whole lot left not even mentioning figuring out what to use for a skin like latex foam or something and the molds. I now work 2 jobs and work on this at least 2hrs a day its so far been just a little bit over a week so I have come pretty far I think.
