The SSS Super-Sensing System: How Go1 "Sees"
One of the Go1's standout features is its SSS (Super-Sensing System), which combines multiple sensors for environmental awareness:
Vision System
- Fisheye Stereo Depth Camera: Wide-angle 3D vision for navigation and obstacle detection
- Additional Cameras (Go1 and Edu): Multi-angle depth sensing provides 360° environmental mapping
- Real-Time Processing: The 16-core CPU and 384-core GPU analyze camera feeds in real-time, enabling dynamic path planning
Other Sensors
- Ultrasonic Sensors: Detect nearby obstacles and measure distances (note: can experience interference in environments with multiple ultrasonic sources)
- IMU (Inertial Measurement Unit): Tracks orientation, acceleration, and angular velocity for balance and coordination
- LiDAR (Go1 Edu only): Optional 3D LiDAR provides high-resolution environmental mapping for advanced applications
The ISS Intelligent Side-Following System: Walk Your Robot
The Go1's ISS (Intelligent Concomitant System) uses patented wireless vector positioning to enable lateral following—a feature that makes the Go1 feel like a genuine companion rather than just a remote-controlled toy.
How It Works
- User Detection: The Go1's cameras and AI processor identify and lock onto the user via visual recognition and radio signal tracking
- Position Calculation: Wireless vector positioning determines the user's location relative to the robot in 3D space
- Adaptive Movement: The Go1 adjusts its speed and path to stay harmoniously by the user's side, navigating obstacles automatically
Real-World Performance
Works Well:
- Open parks, sidewalks, and large indoor spaces
- Consistent walking speed (slow to moderate pace)
- Clear line of sight between user and robot
Limitations:
- Radio signal interference from large obstacles (walls, vehicles) can cause tracking loss
- Crowded environments trigger frequent obstacle avoidance, making following erratic
- Best suited for open routes with minimal obstructions
Real-World Performance Testing: What Can the Go1 Actually Do?
We put the Unitree Go1 through extensive real-world testing across various scenarios:
Speed and Agility
Claim: Top speed of 17 km/h (10.6 mph), breaking the previous record held by MIT's Mini Cheetah (3.7 m/s).
Reality: The Go1 can indeed reach 17 km/h in sprint mode on flat, open terrain. However, for safety and stability, the default speed is limited to around 5-8 km/h during normal operation. At full speed, the Go1 is genuinely impressive—fast enough to keep up with a jogging human but still controllable.
Terrain Handling
- Flat Surfaces (asphalt, tile, hardwood): Excellent. The Go1 moves smoothly and confidently.
- Grass and Gravel: Very good. The Go1 adapts to uneven surfaces with minimal stumbling.
- Stairs: Good (ascending), moderate (descending). The Go1 can climb stairs but requires careful monitoring. Descending is slower and less confident.
- Rough Terrain (rocks, dirt trails): Moderate. The Go1 handles light off-road conditions but struggles with large obstacles or steep inclines.
- Wet/Slippery Surfaces: Caution advised. The Go1 is not waterproof (IP rating not specified) and can lose footing on wet tile or ice.
Battery Life
Advertised: 2-3 hours (standard Go1)
Actual: In mixed use (walking, standing, occasional sprints), we averaged 2-2.5 hours before the low battery warning. Continuous walking at moderate speed yielded approximately 2 hours. Sprint mode drains the battery significantly faster (~1-1.5 hours). The user-replaceable battery design is a major plus, allowing for extended sessions with spare packs.
Payload Capacity
Advertised: 3 kg (Go1 Air), 5 kg (Go1/Go1 Edu)
Actual: We successfully tested the Go1 with a 5 kg payload (small backpack with equipment). The robot's gait stability decreased slightly, and battery life reduced by ~15-20%. Payloads above 5 kg are not recommended—the Go1 becomes unstable and prone to tipping.
Advanced AI Capabilities: The Brain Behind the Bot
The Go1's 16-core CPU and 384-core GPU (1.5 TFLOPS) make it one of the most computationally powerful consumer quadrupeds available.
What the AI Enables
- Real-Time Obstacle Detection: The Go1 uses computer vision to identify and avoid obstacles dynamically
- Terrain Adaptation: Machine learning algorithms adjust gait and posture based on surface type
- Path Planning: The robot calculates optimal routes to destinations, avoiding obstacles and choosing stable footing
- God View Mode: Multi-camera feed transmitted to the app for remote monitoring and control
Limitations
While impressive, the Go1's AI is not fully autonomous. It requires:
- Good lighting conditions for camera-based navigation (struggles in low light)
- Textured surfaces for depth sensing (plain white walls or floors can confuse the system)
- Open environments to minimize obstacle avoidance triggering
