<\/p>\nI’m not done yet, but pretty happy with the progress on “eye mech” \u2013 the mechanical part of the eye movement control.<\/p>\n
A local radio control hobby shop had a transmitter on sale\u2026 the same type that R\/C airplane and higher-end copter folks use. That, plus a receiver, a battery, and four servos, and I’m on my way to some real movement!<\/p>\n
Here’s a picture of the “eye mech plate” I designed and 3D printed, along with two eyes. \u00a08 gauge threaded cable holds the eyes, currently, but I’m working on a smaller cable with a smooth ball on the end to reduce friction and provide stability. \u00a0Servos are strategically mounted \u2013 though they’re not yet hooked up to any control rods. One servo will control left\/right eye movement, and the other will control up\/down. I’ve got room for a third servo to control blinking movement for eyelids \u2013 not yet designed.<\/p>\n
<\/p>\n
You’ll notice the two-level box near and just between the eyes. I’m planning to drill holes through them for the control linkages, to provide “forward\/backward only” movement restriction.<\/p>\n
There’s plenty more work to do, but even at this early stage, it was exciting to fire up the transmitter and watch the servos move!<\/p>\n","protected":false},"excerpt":{"rendered":"
