Describe the rig
Servos grouped into eyes, eyelids, a neck, a jaw or an arm.
Animatronics
Describe the rig, build a library of poses and timed scenes, rehearse them, then drive the real servos from the page.
It drives real servos on your bench, so there is no demo.
Poses and scenarios
Look left, blink, open the jaw, all on a timeline.
Safe to run
Arm with a confirm. The emergency stop is always there.
