Frequently asked questions
How do GR-1 and 4NE-1 compare on price?
GR-1: ~$150,000–$170,000 historically; discontinued and replaced by GR-2 (2024) and GR-3 (2025). 4NE-1: $105,000. Only one of the two has a public unit price; the other publishes a range or enterprise-only terms.
Which has higher payload: GR-1 or 4NE-1?
GR-1 rates a higher payload at 50 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 GR-1 or 4NE-1 actually available to buy?
GR-1 has been discontinued. 4NE-1 is in active development without commercial availability. 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: GR-1 or 4NE-1?
GR-1 has ROS 1 only; 4NE-1 has no ROS support. For research and multi-vendor robotics stacks, native ROS 2 is the strongest signal of ecosystem maturity.
