Project Details
Robot Body & Motion
Bebe uses six MG996R servos at the hip, knee, and ankle joints. Walking is implemented as a sequence of stable open-loop PWM poses that keep the center of mass within a safe region for shuffling steps and turns.
Wand Control & IMU
The handheld wand runs on another Pico W with an MPU6050 IMU. A complementary filter converts tilt into direction and activation magnitude, then streams commands over Wi‑Fi via UDP.
Eyes & Expression
Two MAX7219 LED matrices render animated eyes that cycle through idle, blink, and expressive patterns, making Bebe’s internal state legible while motion control runs independently.
