Frequently asked questions
How do G1 and GR-1 compare on price?
G1: $13,500. GR-1: ~$150,000–$170,000 historically; discontinued and replaced by GR-2 (2024) and GR-3 (2025). Only one of the two has a public unit price; the other publishes a range or enterprise-only terms.
Which has higher payload: G1 or GR-1?
GR-1 rates a higher payload at 50 kg vs 2 kg. Payload ratings are vendor claims and do not always include a duty cycle — peak vs sustained payload can differ significantly.
Is G1 or GR-1 actually available to buy?
G1 is shipping to customers. GR-1 has been discontinued. 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: G1 or GR-1?
G1 has ros2; GR-1 has ROS 1 only. For research and multi-vendor robotics stacks, native ROS 2 is the strongest signal of ecosystem maturity.
Does G1 or GR-1 use LiDAR?
G1 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.
