—
Astribot S1
ROS + Isaac Lab + MuJoCo. Growing research community.
GR-1: ~$150,000–$170,000 historically; discontinued and replaced by GR-2 (2024) and GR-3 (2025). 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.
GR-1 rates a higher payload at 50 kg vs 5 kg. Payload ratings are vendor claims and do not always include a duty cycle — peak vs sustained payload can differ significantly.
GR-1 has been discontinued. 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.
GR-1 has ROS 1 only; 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; GR-1 does not. LiDAR adds cost and complexity but improves obstacle detection in low-light or low-contrast environments.
