Sanctuary AI vs Zhiyuan Robotics — independent, side-by-side analysis.
Phoenix leads in higher payload, while RAISE A1 leads in more DOF, faster speed. Overall, RAISE A1 has an edge in 2 out of 3 compared categories.

—
RAISE A1
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. RAISE A1: $27,500. Only one of the two has a public unit price; the other publishes a range or enterprise-only terms.
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. RAISE A1 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; RAISE A1 has ros2. For research and multi-vendor robotics stacks, native ROS 2 is the strongest signal of ecosystem maturity.
RAISE A1 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.
