Frequently asked questions
How do G1 and L7 compare on price?
G1: $13,500. L7: ~$60,000–$90,000. 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 L7?
L7 rates a higher payload at 20 kg vs 2 kg. Payload ratings are vendor claims and do not always include a duty cycle — peak vs sustained payload can differ significantly.
Are both G1 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: G1 or L7?
G1 has ros2; L7 has no ROS support. For research and multi-vendor robotics stacks, native ROS 2 is the strongest signal of ecosystem maturity.
Does G1 or L7 use LiDAR?
G1 ships with LiDAR for depth sensing; L7 does not. LiDAR adds cost and complexity but improves obstacle detection in low-light or low-contrast environments.
