Frequently asked questions
How do Walker S and A2 compare on price?
Walker S: Contact. A2: $100,000. Only one of the two has a public unit price; the other publishes a range or enterprise-only terms.
Are both Walker S and A2 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: Walker S or A2?
Walker S has no ROS support; A2 has ros2. For research and multi-vendor robotics stacks, native ROS 2 is the strongest signal of ecosystem maturity.
Does Walker S or A2 use LiDAR?
A2 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.
