Frequently asked questions
How do G1 and Sophia compare on price?
G1: $13,500. Sophia: Contact (R&D version available). 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 Sophia?
G1 rates a higher payload at 2 kg vs 1.2 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 Sophia 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 Sophia?
G1 has ros2; Sophia has ROS 1 only. For research and multi-vendor robotics stacks, native ROS 2 is the strongest signal of ecosystem maturity.
Does G1 or Sophia use LiDAR?
G1 ships with LiDAR for depth sensing; Sophia does not. LiDAR adds cost and complexity but improves obstacle detection in low-light or low-contrast environments.
