Frequently asked questions
How do G1 and Walker S compare on price?
G1: $13,500. Walker S: Contact. 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 Walker S?
Walker S rates a higher payload at 15 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 Walker S 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 Walker S?
G1 has ros2; Walker S has no ROS support. For research and multi-vendor robotics stacks, native ROS 2 is the strongest signal of ecosystem maturity.
Does G1 or Walker S use LiDAR?
G1 ships with LiDAR for depth sensing; Walker S does not. LiDAR adds cost and complexity but improves obstacle detection in low-light or low-contrast environments.
