Tracking using 4 PID

Alessandruino's picture

Here is an attempt of tracking using 4 PID:

2 PID are for eyes tracking

2 PID are for head : the head moves in order to reduce the angle of eyes from the center (90 degrees)

  • The next step is to know what is angle range for eye's servos
  • how faster eyes movement should be, respect to the head movement : in the script i made head less responsive than eyes

Making Progress On Automated Sentry Turret Gun

This is ED-209, my makerspace's(http://dhmn.net) automated sentry turret gun.
We're working on a redesign of the hardware, but in the meantime I'm using it to experiment with MRL.


DETECTOR TEST

Here is my attempt to make detector working, first without tracking (only printing Rectangle coordinates)

HERE is the second attempt, with tracking (findcontours sends coordinates to lk opticaltrack)

Here is a first attempt to do what the diagram shows.

Pipelining Progress

trying a different Haar classifier .. there seems to be serval pre-made ones face, eye, full body, profile, mcs eye pair, upper-body, lower-body...  Makes me wonder about creating new classifiers...

 


HARMONIC MOTION APPLIED TO SERVO SWEEP

Testing harmonic motion applied to a servo:

The harmonic motion is a type of periodic motion.

For example, the projection of a point moving around a circle on the diameter of the same circle is an example of harmonic motion.
