Compact Robot Arm + Controller
Learning Objectives
- Build a 5-DOF robot arm from 25 3D-printed parts and 5 servo motors
- Wire an Arduino Uno + PCA9685 servo driver with a 4-potentiometer controller
- Upload and calibrate potentiometer-to-servo PWM code
- Calculate PWM 12-bit counts, torque, and gear ratios in the Lab Notebook
