Frequently asked questions
How do GR-2 and Walker S compare on price?
GR-2: Contact. Walker S: Contact.
Which has higher payload: GR-2 or Walker S?
Walker S rates a higher payload at 15 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 Walker S 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 Walker S?
GR-2 has ROS 1 only; Walker S has no ROS support. For research and multi-vendor robotics stacks, native ROS 2 is the strongest signal of ecosystem maturity.
