—
RAISE A1
Carbon AI fully proprietary. Microsoft Azure backend.
Phoenix: Contact (enterprise). RAISE A1: $27,500. Only one of the two has a public unit price; the other publishes a range or enterprise-only terms.
RAISE A1 rates a higher payload at 80 kg vs 25 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.
