Custom AI Companions, From Character to 3D-Printed Prototype
Roboko is an internal showcase by Inovativi exploring AI voice agents, character design, robotics, and 3D printing.
Eight companion characters
A library of distinct personalities, each designed to be customized, 3D printed, and connected to an AI voice agent.

Nori
Desk companionA calm AI companion for focus, reminders, and quiet daily motivation.

Kibo
STEM learning robotA playful educational robot for learning AI, coding, and robotics hands-on.

Lumi
Creative companionA glowing companion for artists, designers, and creators in flow.

Tiko
Kids / STEM companionA safe, non-human companion designed for supervised learning and play.

Brando
Business mascotA customizable brand mascot robot for reception desks, expos, and campaigns.

Milo
Pet-style companionA cute animal-inspired companion with LED eyes and soft interaction patterns.

Orbit
Space / explorer companionA small explorer robot with astronaut-inspired styling and an optimistic streak.

Echo
Productivity companionA focused assistant for tasks, notes, reminders, and daily check-ins.
One character, configured to a purpose
Color, personality tone, voice, accessories, and the role the companion plays — all configurable. The interactive configurator demonstrates the full flow.
Color theme
Primary, secondary, and accent palettes drive the shell, LEDs, and on-screen identity.
Personality tone
Calm, playful, professional, motivational — tuned to how the agent speaks and behaves.
Voice style
A placeholder voice profile per character, from soft to professional.
Accessories
Modular snap-on parts — headphones, antenna, visor, badge, and more.
Purpose
The role defines the system prompt, memory profile, and default behavior.
Open the configurator
See the live configuratorA conversation with Kibo
A mock exchange illustrating the voice-agent personality layer. In the prototype, this runs through speech-to-text, an LLM personality agent, and text-to-speech.
AI brain, 3D-printed body, simple robotics
AI brain
An LLM personality agent gives each character its voice, tone, and memory — the part that actually holds a conversation.
3D-printed body
A modular printed shell houses the electronics, with replaceable faceplates and accessories per character.
Simple robotics
LEDs for expression, a speaker and microphone for voice, and optional servos for small, lifelike motion.

All processing can run via cloud APIs today, with on-device options on the roadmap.
The stack behind the prototype
A pragmatic mix of accessible hardware and a modern AI layer.
3D-printable shell design
A modular, printable body with replaceable faceplates and snap-on accessories per character.
Raspberry Pi / mini-PC control layer
The main compute runs the agent orchestration, audio I/O, and connectivity.
ESP32 / Arduino for LEDs & servos
A microcontroller drives expressive LED eyes and small servo movements in real time.
LLM-based personality layer
Each character is a configured agent — system prompt, tone, and guardrails.
Memory & profile configuration
Optional, user-approved memory and per-character profiles shape behavior over time.
Camera & sensor integration
Possible presence, touch, and vision sensors for richer, context-aware interaction.
The 60-second showcase film
Planned scenes for the demo video — from character selection to the final gallery.
01Character selection
The gallery of eight companions; a hand picks Kibo.
02Customization
Colors, accessories, voice, and purpose dialed in on the configurator.
033D print
Time-lapse of the modular shell printing layer by layer.
04Assembly
Faceplate, LED eyes, speaker, and controller snapping together.
05AI voice interaction
Kibo wakes, answers a question, and reacts with light and motion.
06Final gallery
The finished companions lined up — and the Inovativi sign-off.
A serious look at AI-plus-robotics, built in-house.
Roboko is how Inovativi explores voice agents, character design, and 3D-printed hardware as one connected system.
Internal prototype / showcase concept — not a certified consumer robotics product.
