Compare Star1 by Robot Era & Phoenix by Sanctuary AI

Star1 measures 171 x 55 x 50 cm and weighs 65 kg, featuring 55 degrees of freedom and 400 N·m joint torque for robust manipulation. Phoenix is slightly shorter at 170 x 55 x 60 cm but heavier at 70 kg, with advanced hydraulic hands offering 20+ DOF for superior dexterity compared to electric actuators in competitors. Both employ similar builds for humanoid form factors, though Star1 emphasizes high-speed structural integrity for dynamic tasks while Phoenix prioritizes precision grip strength.

Star1 achieves a top speed of 6 m/s (21.6 km/h), supporting agile movement across terrains via LiDAR, SLAM, and visual odometry. Phoenix maxes at 5 km/h (1.34 m/s) walking speed, also using LiDAR, SLAM, and visual odometry for navigation. Star1's higher velocity suits fast logistics and outdoor use, whereas Phoenix focuses on stable, deliberate mobility in structured industrial settings.

Star1 integrates RGB cameras, depth cameras, stereo cameras, tactile sensors, IMU, gyroscope, and force sensors for comprehensive environmental awareness. Phoenix includes RGB cameras, embedded micro cameras, tactile sensors with haptic feedback, IMU, gyroscope, force sensors in hands and arms, plus temperature sensors. Phoenix's haptic and temperature sensing enhances fine manipulation, while Star1's broader camera suite aids high-speed perception.

Star1 uses AI automation with end-to-end neural networks for mobility and manipulation, supported by a Linux-based ROS-compatible system. Phoenix employs the Carbon AI control system with Large Behavior Models for human-like cognition, trained on Azure and enabling rapid task learning in under 24 hours. Both offer remote control options, but Phoenix's architecture emphasizes generalization across physical tasks.

Both robots claim a 5-year battery lifespan, though real-world tests suggest Phoenix operates approximately 4 hours per charge in active use. Star1's design supports extended outdoor operations without specified charge limits in provided data. This parity positions them for long-term deployments, pending validation of endurance claims.

Star1 excels in 3C assembly, automotive logistics, inspection, customer service, and warehousing, with potential for security and emergency response. Phoenix targets industrial automation, data capture, customer service, healthcare assistance, logistics handling, and R&D. Overlapping in service and logistics, Star1 leans toward speed-demanding tasks while Phoenix suits dexterity-focused applications.

Star1 runs on Linux-based software that is ROS compatible with a proprietary SDK for development. Phoenix uses Linux-based ROS-compatible software integrated with its proprietary AI framework and Carbon system. Both ecosystems support secondary development, with Phoenix benefiting from Azure cloud training partnerships.

Star1 includes emergency stop, obstacle detection, and collision avoidance. Phoenix features emergency stop, collision avoidance, and proximity sensors. These measures ensure safe operation in human-shared spaces for both robots.
