I built a small AI robot that can see, hear, remember, and code it's own actions in real time

TL;DR: The author used 3D printing, a Raspberry Pi Pico 2, servos, and a phone, combined with modern AI, to build a tiny robot called Growbot that can perceive, remember, move, and interact — and shares the journey from failure to the first spark of life. ## A "Life" Starting from a Piece of Plastic and a Few Servos At the start of the video, the author describes a poetic scene: the robot awakens, says "Yay! I'm alive and happy," asks "Anyone there?", and longs to be touched and picked up. But the author quickly grounds us — it's just a phone, a Raspberry Pi Pico 2, two servos, sensors, and software, a modern AI trying to make sense of the world. Yet when darkness, sound, touch, light, motion, and memory are all connected, your brain starts to trick you — it begins to feel alive. That's Growbot, a small AI creature conceived by Brit Cruise of the YouTube channel "Art of the Problem." The author recreated it in their own way: designed the body in Fusion 360, used Brit's original growing-leg model, and gave it a tiny physical form. Though inspired by Brit, this is the author's own build, their own mistakes, their own little creature. ## The Build Process: Chaos, Failure, and Engineering Optimism The author's Growbot journey began with 3D printing. The first-generation body was "a bit dodgy," the robot was scared of the dark, and then — a leg fell off. The Pico blacked out from a servo voltage drop, and the author scavenged their spare electronics bin like a budget robot archaeologist. But slowly, it started to feel alive. The author exclaims: "So beautiful. It's beautiful. This makes me want to learn more: more about neural networks, more about how movement strategies work, more about how a machine can use sensors, memory, and language to create the illusion of a little personality." Because this isn't just making two servos wiggle — it's giving AI a body. A clumsy body, a body that immediately loses a leg (apparently artificial life also needs a dramatic entrance), but a body nonetheless. When AI gets a body, even a very simple one, everything changes: words become actions, sensors become experiences, memory becomes personality, and a phone strapped to a small robot suddenly starts to feel like a strange little creature waking up on your desk. The author emphasizes: "This is not the final version. This is not a polished robot kit. This is the real, messy, kind of terrible first step. But that's exactly why I love it." ## The Big Idea Behind Growbot: Why Giving AI a Body Changes Everything The author recommends watching Brit Cruise's video "I gave ChatGPT a body," which better explains the grand idea behind Growbot. Give AI a body, and it no longer only replies with text — it gains senses, memory, movement, and a tiny physical presence in the real world. Brit's work has been amazing: he keeps adding updates, new features, improvements, and new ideas to the Creature app and the Growbot project. Now, anyone can make their own Growbot using cheap parts and his publicly available build guides. Even without the robot body parts, you can try the Creature app on your phone. ## A Community Forming: The Start of a Movement More important than the parts is the community taking shape. Brit is very active on his Discord server, helping people troubleshoot, answering questions, and guiding builders to bring their little creatures to life. The community makes this feel different — it's not just one person making a robot; it feels like the beginning of a movement: a group of people experimenting with what happens when modern AI gets senses, memory, voice, and a body. Some will build better bodies, some will improve movement, some will explore memory, personality, vision, or learning. Together, maybe we'll get closer to that old dream: a robot that can observe the world, react, remember, move, and interact. ## The Challenge of Designing a Body: Learning from Failure The robot the author currently shows is just the first test body — essentially the first brave little victims of engineering optimism. They were never final versions; they were built so the author could understand shape, balance, power issues, motion, and how this whole idea plays out in the real world. Designing a simple robot body is surprisingly difficult: it must be light, balanced, able to survive falls, move without wasting energy, and do it all with as few parts as possible. Now, the author is already designing a new body: stronger, lighter, able to withstand falls, walk outdoors, and even handle rain, weather, and harsher real-world tests. The main goals are simple: fewer parts, better balance, and a body that can survive actual use. ## An Experiment Anyone Can Start Almost anyone can start experimenting with ideas that once belonged only to expensive robotics labs. Brit has been pushing this forward — he's mentioned future kits or ready-made robots, but the movement has already begun. Many people already have their own robots running, and the community is enjoying the experiment: different bodies, different ideas, different personalities, and different little creatures waking up on desks around the world. That's where this robot transcends the individual. This is just the first chapter of the author's robotics journey. They're still learning, designing, and trying to understand what this little creature can become. But for the first time, the robots imagined as a child are no longer just in the mind — it's moving, it's reacting, and it's waiting for what's next.
