Automatic Chopsticks
July 6, 2021
I started this project about two years ago, and have played with it off and on. What you see here is the second iteration with a custom manufactured PCB.
By combining a servo motor, some springs, and a laser range sensor, the chopsticks can detect when they are held near a surface or food item and close. They open again, after a brief delay to allow you to eat, when no object nearby is sensed.
