Frequently asked questions
How do GR-1 and L7 compare on price?
GR-1: ~$150,000–$170,000. L7: ~$60,000–$90,000.
Which has higher payload: GR-1 or L7?
GR-1 rates a higher payload at 50 kg vs 20 kg. Payload ratings are vendor claims and do not always include a duty cycle — peak vs sustained payload can differ significantly.
Are both GR-1 and L7 shipping to customers?
Yes. Both are commercially available as of the last review. Delivery timelines and customer geographies vary per vendor — check the manufacturer page for each.
Which is better for ROS-based development: GR-1 or L7?
GR-1 has ROS 1 only; L7 has no ROS support. For research and multi-vendor robotics stacks, native ROS 2 is the strongest signal of ecosystem maturity.
