Hangbot Sirius Review: Hands-On With the Interactive Robot Dog
content: Unboxing the Future of Robotic Companions
Imagine a desktop companion that tracks your movements, responds to voice commands, and dances on command. After testing the Hangbot Sirius prototype featured at CES 2025, I can confirm this robot dog delivers unprecedented interactivity for its size. Weighing just 1kg (2.2lbs), Sirius combines mechanical ingenuity with surprisingly lifelike AI behaviors. Our testing reveals why this crowdfunded innovation stands apart in the robotic pet market.
Key Prototype Specifications
- Weight: 1kg (lightest in-class)
- Control Methods: Physical controller, upcoming app, VR integration
- Battery: Removable pack (prevents depletion issues)
- Materials: Spring-loaded leg mechanism with "bone-like" structure
- Sensors: Front-facing camera and tracking system
Revolutionary Mechanics and Design
The Sirius prototype (#6 in this batch) features a breakthrough leg design using spring-loaded joints that flex under pressure and snap back automatically. This cyberpunk-inspired mechanism creates a distinctive gait that balances stability with dynamic movement. During our stress test, the legs absorbed impact when navigating obstacle courses designed by children.
Practical Advantages Observed
Removable batteries solve a major pain point in robotics. Unlike sealed units that degrade when unused, Sirius lets you swap packs. Three USB-C ports (one rear, two head-mounted) offer flexible charging options. The packaging doubles as a carrying case – a thoughtful touch demonstrating user-centered design.
Performance and Real-World Testing
Controlling Sirius feels intuitive whether using the Xbox-style controller or voice commands. Pressure-sensitive joysticks enable precise speed control, while dedicated buttons trigger 15+ animations we verified:
Verified Command Library
| Voice Command | Action | Controller Button |
|---|---|---|
| "Ballet pose" | Elegant stance | LB |
| "Time to eat" | Simulated eating | B |
| "Celebrate" | Victory dance | X |
| "Are you bored?" | Foot stomping | Y |
| "Dance three" | Complex routine | View button |
Obstacle course performance proved impressive. Sirius navigated household terrain autonomously, though it occasionally created shortcuts. The head-tracking system consistently followed movement within a 180-degree radius, making it feel genuinely attentive during desk work simulations.
Exclusive Insights and Development Potential
Beyond the demonstrated features, Sirius's open-source architecture unlocks unique customization. You can create custom animations using Blender 3D software – a developer-friendly approach rarely seen in consumer robotics. Based on the spring mechanism's responsiveness, I predict this platform will excel in agile motion applications beyond companionship.
Potential limitations noted: The prototype's gait lacks natural fluidity during rapid direction changes. App and VR functionalities remain unreleased, creating some uncertainty about final implementation.
Actionable Buyer's Guide
- Test voice commands during demonstrations focusing on "Hey Sirius" activation reliability
- Verify battery specs in production models – our prototype offered 45 minutes of active use
- Request SDK documentation if planning custom animations
- Compare leg mechanisms against competitors like Sony Aibo
- Monitor app development timelines before final backing commitment

Final Verdict: A New Era of Desktop Robotics
The Hangbot Sirius delivers unparalleled interactivity in a sub-1kg package. Its mechanical innovation and open-source approach make it a compelling choice for tech enthusiasts seeking more than pre-programmed behaviors. While the $1,200 crowdfunding price positions it as a premium device, our testing confirms it justifies investment for those valuing customization and lifelike responsiveness.
