Walker S vs Astribot S1: Specs, Price & ROS Support Compared (2025)

Walker S: Contact. Astribot S1: $250,000. Only one of the two has a public unit price; the other publishes a range or enterprise-only terms.

Walker S rates a higher payload at 15 kg vs 10 kg. Payload ratings are vendor claims and do not always include a duty cycle — peak vs sustained payload can differ significantly.

Yes. Both are commercially available as of the last review. Delivery timelines and customer geographies vary per vendor — check the manufacturer page for each.

Walker S has no ROS support; Astribot S1 has ros2. For research and multi-vendor robotics stacks, native ROS 2 is the strongest signal of ecosystem maturity.

Astribot S1 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.
