Performance Testing

Mobility and Locomotion

The Go2's locomotion capabilities are simply outstanding. During our testing phase, we evaluated the robot across multiple terrain types:

Flat Surfaces: The Go2 moves with remarkable stability and precision on flat ground. Its gait is smooth and natural, with minimal vibration even at higher speeds.

Stairs and Steps: Climbing stairs is where the Go2 truly shines. The robot handles standard residential stairs with confidence, automatically adjusting its gait pattern for optimal stability.

Outdoor Terrain: From grass to gravel, the Go2 adapts its walking pattern intelligently. We tested it on hiking trails, sandy beaches, and even light snow conditions.

Battery Performance

Real-world battery life varies significantly based on usage patterns:

• Light use (walking, basic movements): 3.5-4 hours
• Moderate use (running, payload carrying): 2.5-3 hours
• Heavy use (continuous running, maximum payload): 2-2.5 hours

The charging system is efficient, bringing the robot from 0% to 100% in approximately 4 hours.

Software and Control

The Go2's software ecosystem is impressively mature. The companion mobile app provides intuitive control options, from basic remote control to complex programming interfaces. For developers, the SDK offers extensive customization possibilities.

Key Software Features

• Remote Control: Responsive app-based control with minimal latency
• Autonomous Following: Person and object tracking capabilities
• Programmable Behaviors: Custom movement patterns and responses
• OTA Updates: Regular firmware improvements and new features

Real-World Applications

During our testing period, we explored various practical applications:

Security and Patrol

The Go2 excels as a mobile security platform. Its quiet operation and ability to navigate complex environments make it ideal for property monitoring.

Education and Research

For educational institutions, the Go2 provides an excellent platform for robotics education. The comprehensive documentation and development tools support both beginner and advanced programming.
