Frequently asked questions
How do GR-2 and Astribot S1 compare on price?
GR-2: ~$150,000+, enterprise only; no US sales channel. Astribot S1: $250,000. Only one of the two has a public unit price; the other publishes a range or enterprise-only terms.
Which has higher payload: GR-2 or Astribot S1?
Astribot S1 rates a higher payload at 10 kg vs 3 kg. Payload ratings are vendor claims and do not always include a duty cycle — peak vs sustained payload can differ significantly.
Are both GR-2 and Astribot S1 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: GR-2 or Astribot S1?
GR-2 has ROS 1 only; Astribot S1 has ros2. For research and multi-vendor robotics stacks, native ROS 2 is the strongest signal of ecosystem maturity.
Does GR-2 or Astribot S1 use LiDAR?
Astribot S1 ships with LiDAR for depth sensing; GR-2 does not. LiDAR adds cost and complexity but improves obstacle detection in low-light or low-contrast environments.
