Frequently asked questions
How do Phoenix and A2 compare on price?
Phoenix: Contact (enterprise). A2: $100,000. Only one of the two has a public unit price; the other publishes a range or enterprise-only terms.
Which has higher payload: Phoenix or A2?
Phoenix rates a higher payload at 25 kg vs 15 kg. Payload ratings are vendor claims and do not always include a duty cycle — peak vs sustained payload can differ significantly.
Is Phoenix or A2 actually available to buy?
Phoenix is in active development without commercial availability. A2 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.
Which is better for ROS-based development: Phoenix or A2?
Phoenix has no ROS support; A2 has ros2. For research and multi-vendor robotics stacks, native ROS 2 is the strongest signal of ecosystem maturity.
Does Phoenix or A2 use LiDAR?
A2 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.
