视频链接: How to Make a Compact Animatronic Eye Mechanism with 3D Printing and Arduino – YouTube




This project is an upgraded version of my previous design, a highly compact and robust animatronic eye mechanism which uses 3D printed components and an Arduino microcontroller. If you are able to get hold of servo ball-links and pushrods, and are reasonably competent with 3D printing, this is the eye mechanism project I’d recommend most!

PARTS: https://amzn.to/32PAPo7 (this kit should cover you) Around 40* M2 x 6mm screws 6* 10mm M2 screws 6* MG90s servo screws (these come with the servos: https://amzn.to/33VfIlF) 4* M2 Servo Ball-links: https://amzn.to/2Kq8fDK 4* M2 x 25mm Pushrod Connectors: https://amzn.to/32XQXEt (keep in mind this is just 2mm threaded bar – you could always cut down a 25mm bolt or some plain threaded rod) Arduino Uno: https://amzn.to/2XoMolo (or anything that can accept three analogue signals, one digital and communicate through SDA/SCL ports) Adafruit PCA9685 16-Channel Servo Driver: https://amzn.to/2NQeNNT 5V Power Supply, around 4A is more than enough. Here is mine (http://tiny.cc/is4cdz) A female DC power jack to match your power supply, to be soldered to the servo driver board 2-axis Joystick: https://amzn.to/2NR4JnY Potentiometer (optional): https://amzn.to/2r0nADS Push-to-make switch (Some joysticks have this built in, but its easier to control when its seperate: https://amzn.to/32Wnvyh) 10k Resistor: https://amzn.to/374seRU Jumper cables: https://amzn.to/2NToCuw 6* MG90s servos: https://amzn.to/2NToBqs Also, a pin vice hand drill might be useful for adjusting hole sizes: https://amzn.to/2CLsCqG
