Robots are fascinating, but they often come with a hefty price tag and complexity, leaving enthusiasts disappointed. But here's a game-changer! Dorian Todd introduces Sesame, a quadruped robot you can build at home for less than $60, making robotics accessible to all. And this isn't just any robot; it's a walking, expressive companion.
Sesame's design philosophy is unique. Instead of aiming for high-performance or complex sensors, it prioritizes simplicity and ease of assembly. The robot's body is 3D-printed, with cleverly designed mechanical links that minimize the need for support material. Each part is numbered, ensuring a stress-free building experience. With eight servo motors, Sesame moves with a full range of motion, bringing it to life with walking, posing, and playful animations.
The electronics are compact and efficient, featuring an ESP32 S2 Mini microcontroller or a custom PCB for streamlined assembly. A lithium-polymer battery powers the robot, and a tiny OLED display adds a touch of personality, displaying animated faces. Sesame even hosts its own Wi-Fi network, allowing control via a web page, and for the adventurous, there's Sesame Studio, a tool to create custom animations.
The best part? All the resources are freely available on GitHub, so you can embark on your robot-building journey today! But here's where it gets controversial - is this the future of robotics, making it a hobby for all, or just a fun but limited project? Share your thoughts below!
