AI Robot that Thinks, Acts & Adapts
Run AI agents
in the real world.
Palmimo is a customizable, general-purpose AI robot that thinks and acts on its own—an interactive companion that meets your eyes, answers your voice, and speaks through expressions and gestures.
Palmimo DevKit is a desktop development kit you drive with your own code, and an open platform built for co-creation.
Sees, listens, talks, walks. A new partner for the AI era
Palmimo isn’t a machine built for a single fixed job. It’s a general-purpose AI robot, designed and built in Japan, that can take on many roles. With the warmth of wood in its design and lifelike movement, it’s made to fit naturally into the spaces where people live and work—homes, offices, and beyond.
Palmimo DevKit opens all of it up to code. From testing AI models in the physical world to building custom apps, it’s an experimental platform for researchers and engineers.
- EyesRecognizes people and surroundings with its camera
- EarsHears voices and sounds through its microphones
- VoiceTalks to you with synthesized speech
- FaceShows expressions on its round display
- BodyWalks, dances, and bows on six legs
- BrainAI decides how to behave, autonomously
Why Physical AI—and Palmimo DevKit—now.
Why now
- More and more software engineers are getting into hardware and robots
- Open robots and developer tools that support them are multiplying worldwide
- Most of them come from outside Japan. We want Japan to contribute, too
Palmimo DevKit is the entry point
- Customize and drive a robot with your own code, even without hardware knowledge—we want to deliver that thrill
- An AI robot made in Japan, built together with developers around the world
- A gateway for learning, and a tool for bringing Physical AI into the real world
To move Physical AI forward
Grow the number of people who can work across software and hardware.
The freedom of open source
You don’t need to know hardware or robotics—with some software experience, you can get started. That’s the Palmimo DevKit developer experience. In dry-run mode, you can try every motion API before the robot even arrives.
And the SDK is only the beginning. We’ll progressively open up more of the development stack, starting with the robot model for simulation.
Drive it with a few lines of code, or rewrite the driver internals—how deep you go is up to you. Everything you can customize is documented on GitHub / Docs.
Layer 4 — Your code
Your code
Import it and write a few lines. Drive the robot without knowing the hardware.
Layer 3 — SDK
SDK — the one window you touch
Just call robot.forward(). Most of the work happens in this layer.
Layer 2 — Driver abstraction
Driver abstraction layer
Swap the driver to go from dry-run to the real robot. New backends such as simulators plug in here.
Layer 1 — Hardware
The body — 21 axes
21 servos (6 legs × 3 axes, neck 3 axes), camera, microphone, speaker, display.
Drive the robot from your own application
“I made a robot move!”—that moment of wow, for you.

robot.wave() # wave
robot.look(pitch=0.3, yaw=0.5) # turn the head

What you can build with Palmimo DevKit
AI companions / interaction research
It recognizes people and reacts—wave, and it waves back; speak, and it talks with you. It behaves according to the situation and the flow of conversation. Explore natural human–robot interaction through an interactive companion.
PoCs for offices, stores, and exhibitions
Reception and guidance, internal FAQs and equipment help, spatial staging, conversations with visitors. Validate use cases that run in real physical spaces.
AI agents × hardware experiments
Turn LLM tool calls directly into robot actions. Building on an agent implementation that runs a ReAct loop, connect AI in software to physical behavior.
Research, education, workshops
A platform for HCI and Physical AI research, corporate R&D training, and university labs. We’ll also be providing environments for robot learning, such as Sim2Real and VLA fine-tuning.
Multi-robot service design
One unit greets visitors at reception while a second unit on another floor shows them the way. Information from units serving people across a facility flows into a hub unit in the office—try out how multiple Palmimo DevKits share information and work together.
Integration with your data and systems
Personalize responses based on customer and member data or your own content, and feed conversations and reactions back into your platform as interaction data. Connect via API to existing services and business systems to create new touchpoints for your assets.
Connect Palmimo DevKit to your data and services
Palmimo DevKit is an open platform built for co-creation. Connect your company’s assets—customer and member data, content, your own services, business systems—via API, MCP, and SDK, and deliver personalized responses to users based on that data.
Conversations and reactions can flow back into your own platform as interaction data, according to your settings. Put your assets to work and strengthen them in a loop, starting with a real robot that fits on a desk.
A hub that drives both digital and physical
It reads the situation and acts ahead of you. Give it a voice command, and it works out the operations needed and carries them out.
With Palmimo DevKit as the hub, operations on business systems (search, update, register, notify) and actions in the physical world (displays, lighting, IoT devices, instructions to other robots) all run from a single autonomous loop.
Jizai’s team works alongside you
From AI and software (designing conversations and behavior, selecting AI models, integrating with your systems and APIs, building business apps) to hardware (adding external sensors and devices, customizing the exterior, designing multi-unit deployments) to training (hands-on sessions, in-house study groups, guidance on running a PoC).
