IDEA

Talking heads on podiums idea, trying to get a basic idea of how this would work with a servo (for the neck) and the sensor with mount (for where the head would be):

Wanted to thank Darpan Pudasaini for the detailed explanation of his experience with the bearing assembly concept, he just took this step of the project from an idea to a confirmed plan of action we can begin to execute on.

You could pick up a nice one at a scrap dealer in case you have one. All it would require may be a couple of micros switches with timer for movement.

Anton Voltchok can you explain better how the eye tracking works like dimensionally…like is it just one plane? like what data is coming in…like left right, up down, etc? I want to get more clarity on how the servo needs to respond. thanks

I’ll have to start a new post to fully describe it Steven Reubenstone , essentailly the algorithm is producing a tremendous amount of data every 8 milliseconds:

  • which I’m condensing into 4 sets of coordinates
  • based on this, I’m doing some math to turn them into somewhat usable ratios
  • the servo would only need 1 of these ratio variables which turns the persons x axis position into a Y axis rotational angle to turn the head (as I mentioned I already wrote this, you can see in the project video the head is rotating on the Y axis)
    -we would multiply the variable by the total rotation of the servo, then divide that number in half and then we have our servo with head on it looking straight when the person is looking straight at the head. This part is actually the really easy part, what’s a bit more difficult and what I’m working on next is having the web app and servo motor work together simultaneously (which I think I have figured out) Anyways, I’ll be posting a bunch more about all of this stuff and releasing a repo when I get a chance.

I actually just got confused for a second – doesn’t a servo only operate about one axis?

Yes steve, please let me check with the team I helped on the project. Since it was sometimes ago I dont have it with me. Will also check if they could rovide the 3d design that I had made back then.
