Frequently asked questions
Which is cheaper: Walker S2 or A2?
Walker S2 is cheaper at $90,000 vs $100,000 for A2. Note that lower price does not imply lower total cost of ownership — see the TCO calculator on the Explore page for utilisation-adjusted figures.
Are both Walker S2 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 S2 or A2?
Walker S2 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 S2 or A2 use LiDAR?
A2 ships with LiDAR for depth sensing; Walker S2 does not. LiDAR adds cost and complexity but improves obstacle detection in low-light or low-contrast environments.
