A tiny four-legged robot with a real-time brain, onboard vision, and a natural voice — built from scratch on commodity hardware.
Echo was built to feel alive — to move, notice you, and talk with you, all running on its own little body.
Walks, runs, and dances on four legs with a Stanford-Pupper-inspired gait.
Understands natural language and talks back in a warm, natural voice.
Recognizes objects and faces with an onboard camera, and follows you around.
ARTOS, a custom almost-real-time OS, keeps body and mind in sync.
No black boxes. Every part is off-the-shelf and hackable — here's the whole stack.
Echo went from a Fusion 360 sketch to a walking robot on a desk — one printed part at a time.
Every joint, thigh, and support modeled in Fusion 360, sized to hug MG996R and MG90S servos exactly.
Skeleton printed on an Anycubic Kobra — iterating tolerances until the servos slid in snug.
Eight servos bundled into a PCA9685 driver; camera, mic, and speaker onto the Pi.
ARTOS calibrates each servo, runs the gait, and wires vision + voice into one loop.
Watch Echo find its feet. (Full walk-and-talk reel dropping soon.)
