Let’s get one thing straight — this isn’t a toy dog. Hengbot Sirius is a quadruped robot with muscles, manners, and emotional intelligence. It can do flips, mimic your pet, respond to voice, vision and touch, and even learn routines through code or behavior.
Launched as the world’s first trainable AI robotic dog, Sirius is more than hype. It’s a mobile AI platform, a programmable STEM companion, and a surprisingly charming sidekick — all under 1 kg.
And if you think this is just some overdesigned plastic gimmick… wait until it makes eye contact, blinks at you, and does a backflip.

Inside the Mind of a 1KG Genius
Sirius isn’t driven by brute force. It’s powered by a highly optimized quad-core CPU and a lightweight OS designed to execute real-time AI routines. That includes facial tracking, touch recognition, voice parsing, and emotional simulation — all happening locally.
Multimodal interaction is the name of the game: you wave, it responds. You speak, it tilts its head. You frown, it tries to cheer you up with movement and light.
The result? A robotic dog that doesn’t just move — it connects.
Design: When Robotics Meets Real Emotion
Let’s call this section…
“Backflips With Soul”
Hengbot could’ve gone with a clunky, industrial frame. Instead, they gave Sirius a bionic bone-inspired chassis. Every joint has flexibility and weight distribution like a real creature.
The ears light up when it’s curious. The back glows when it’s active. The LCD screen isn’t a gimmick — it delivers genuine personality. Happy blinks, shy glances, alert expressions — all rendered in real time.
Everything feels thoughtful. Even the pogo-dock charger has satisfying magnetic feedback. It’s not just futuristic; it’s friendly.
Real World Use: From Living Rooms to Labs
You can dance with it. You can code for it. You can literally use it as a digital delivery dog for gifts. Sirius adapts to you.
Here are just some of the modes this robot supports:
• Leash Mode — It follows you around indoors with camera tracking
• Pet Mirror Mode — Learns and mimics your real pet’s sounds and actions
• First-Person View Mode — Control its movement and see through its “eyes”
• Romantic Mode — Deliver a gift or message as a surprise package
• Custom Persona Mode — Train it with your tone, reactions, and preferences
• Dev Mode — Full SDK access (EDU version) for building your own robot logic
• DIY Skin Mode — Print your own shell for it and create unique outfits
It’s not just fun — it’s a robotics sandbox for coders, creators, and dreamers.

How It Stacks Up
• vs. Loona by KEYi
• Loona is cute and expressive but limited to wheels and simple responses. Sirius offers full quadruped motion, real AI interaction, and dev support.
• vs. Unitree Go1 Mini
• Unitree is more athletic but purely industrial. Sirius adds personality, emotion, and creative APIs — better for education, play, and design.
Verdict: If you want a robot dog that looks alive, feels responsive, and evolves with you, Sirius has no direct rival right now.
What Others Say
“This isn’t just a robot dog — it’s a personality platform with heart and hardware.” — TheTechBreakdown
“Sirius won Red Dot 2025 for a reason. It’s equal parts engineering and art.” — CES Live
Cons
• 40–60 min of battery is limiting for long sessions
• Bluetooth 4.2 feels dated in 2025
• No waterproofing — indoor use only
• Coding with Python/C++ requires learning curve
• Only PRO/EDU tiers include key accessories (battery, joystick)
FAQ
• Does Sirius need the internet to work?
No. All voice, vision, and response logic is offline. OpenAI support optional for future.
• Can I program my own actions?
Yes — either through app-based training or full SDK in EDU tier.
• Is it safe for kids?
Yes. It’s quiet, safe, and intuitive. Best for ages 8+ with adult setup.
• Can I customize its look and sound?
Yes — 3D-printable skins, downloadable voice packs, RGB profiles.
Final Verdict
Sirius isn’t just the world’s first trainable AI dog — it’s a living robotics platform wrapped in a pixelated personality. From Red Dot–winning design to real AI interaction and hackable bones, it offers more than any pet bot in its class.
Whether you’re a developer, an educator, or a curious soul with a love for digital creatures — this is your ultimate robotic companion.
