prototype test

(late post, from Dec 3)

findings and thoughts:

-This definitely reinforces my idea of using a support between the servos and the silicone

-I need to raise the three servos on the bottom

-The thread attaching the servos to the rubber was too taut so it was pulling the face altogether instead of individual parts of the face (that and of course that there wasn’t any support in place)

It works! Thanks Alan for all your help in the code!

Alan moving his arms to affect the motors (at this point, the code simply was: when the left hand is higher than the right, move the motors to n position; when the right is higher than the left, move motors to t position

Communication (Kinect/Synapse, Processing, and Arduino): Thanks to Alan, as of November 19th, the code is working! Communication from a person’s movement to the motors’ movement is a go!!

Motors: I now have my six motors! I need to mount them on a back support model (see previous prototype images) and calibrate them so that each moves in a desired manner.

Face: I am sculpting what I hope will be the final form of the face. I just got a new batch of silicone to mix and make a mold of the face from. Thoughts: last time my process was: made face out of clay, made plaster mold of face (using gauze), poured silicone mix into the negative of the plaster mold and pressed the positive clay face into that (so I pushed out the excess and got a “hollow” negative). However, the silicone positive came out too thick. The following are ideas I’m thinking about for making the silicone “mask”:

  • make a plaster gauze positive mold from the clay face as well as a negative (using plaster of paris); pour silicone into negative, displace excess by pushing in the gauze positive
  • include a pour spout; brush on rubber over the clay face (create a rubber mold), cover that in plaster; create a positive plaster piece….then when casting the silicone, pour it into the “two part” mold
  • simply brush the silicone directly onto the clay face in a uniform and neat manner

Servo support/backing: I am using balsa wood for the prototype, but it’s been pointed out that that method may not be strong enough for the motors. What else should I use and how should I cut out spaces to sit the servos in? Acrylic, plywood? Laser cut?

And of course, I need to put it all together and test out the duration and behavior of the piece on its own (and the separate components together), and then have folks interact with it to observe what adjustments I should make.
