Which has higher payload: Phoenix or GR-2?
Phoenix rates a higher payload at 25 kg vs 3 kg. Payload ratings are vendor claims and do not always include a duty cycle — peak vs sustained payload can differ significantly.
Is Phoenix or GR-2 actually available to buy?
Phoenix is in active development without commercial availability. GR-2 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 GR-2?
Phoenix has no ROS support; GR-2 has ROS 1 only. For research and multi-vendor robotics stacks, native ROS 2 is the strongest signal of ecosystem maturity.
