Frequently asked questions
How do Forerunner K2 and Reachy 2 compare on price?
Forerunner K2: $20,000. Reachy 2: ~$70,000–$100,000. Only one of the two has a public unit price; the other publishes a range or enterprise-only terms.
Which has higher payload: Forerunner K2 or Reachy 2?
Forerunner K2 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.
Is Forerunner K2 or Reachy 2 actually available to buy?
Forerunner K2 is open for preorders. Reachy 2 is shipping to customers. Status reflects the vendor's published commercial position as of the last review and can change between announcement and actual delivery.
Which is better for ROS-based development: Forerunner K2 or Reachy 2?
Forerunner K2 has no ROS support; Reachy 2 has ros2. For research and multi-vendor robotics stacks, native ROS 2 is the strongest signal of ecosystem maturity.
Does Forerunner K2 or Reachy 2 use LiDAR?
Reachy 2 ships with LiDAR for depth sensing; Forerunner K2 does not. LiDAR adds cost and complexity but improves obstacle detection in low-light or low-contrast environments.
