How to Build a Simple 3D Printed Arduino Animatronic Eye Mechanism

Here’s how I build my simplified 3D printed arduino animatronic eye mechanism. This is a good option if you’d like to try out some DIY arduino robotics but don’t necessarily have access to certain specialist hobby components, high-quality 3D printing or workshop tools. If you need more help, check the thorough text instructions on instructables: Contact: enquiries@ Discord Server: Support me on Patreon for a look behind the scenes and a Nilheim Mechatronics sticker pack: Parts and Materials needed for this project: 3D Printer Filament: PLA is fine although I’d recommend you use a good brand because some parts are quite small and fragile. ABS is good for making realistic eyes but not necessary. 6x SG90 Micro Servos: Various M2 and M3 screws although any screws roughly that size should work ok. A kit like this: should cover you. Arduino: This design was tested using a genuine Uno, but it’s likely that any board which has SDA/SCL pins, 3 analogue inputs and a digital input will work. Arduino Uno: Servo Driver Board: I opted for a 16 channel PWM driver board from Adafruit: 5V Power Supply, around 4A is more than enough. Here is mine () A female DC power jack to match your power supply, to be soldered to the servo driver board Jumper Cables: Joystick: Potentiometer (10k ohms is generally a good value to use: ) Momentary switch(Some joysticks have this built in, but its easier to control when its seperate: ) 10k Resistor: Tools:​ A pin vice hand drill might be useful for adjusting hole sizes: Downloads: Check the blog post on the Nilheim Mechatronics website:
