Phoenix
—
Astribot S1
Carbon AI fully proprietary. Microsoft Azure backend.
Phoenix: Contact (enterprise). Phoenix Gen 8 still in development; since mid-2026 Sanctuary also sells its Carbon control software on third-party industrial robots. Astribot S1: Quote-only (B2B); official site lists no price. Chinese reports cite ~CNY 500,000 (~$69,000) for the research edition; third-party estimates $96,000–$150,000. Volume shipments in China since late 2025.
Phoenix rates a higher payload at 25 kg vs 5 kg. Payload ratings are vendor claims and do not always include a duty cycle — peak vs sustained payload can differ significantly.
Phoenix is in active development without commercial availability. Astribot S1 is shipping to customers. Status reflects the vendor's published commercial position as of the last review and can change between announcement and actual delivery.
Phoenix has no ROS support; Astribot S1 has ros2. For research and multi-vendor robotics stacks, native ROS 2 is the strongest signal of ecosystem maturity.
Astribot S1 ships with LiDAR for depth sensing; Phoenix does not. LiDAR adds cost and complexity but improves obstacle detection in low-light or low-contrast environments.
