Frequently asked questions
How do Forerunner K2 and CL-1 compare on price?
Forerunner K2: $34,800. CL-1: Prototype (2023), never sold; superseded by CL-3 / Oli (full-size humanoid now sold on limxdynamics.com). Only one of the two has a public unit price; the other publishes a range or enterprise-only terms.
Is Forerunner K2 or CL-1 actually available to buy?
Forerunner K2 is shipping to customers. CL-1 has been discontinued. 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 CL-1?
Forerunner K2 has no ROS support; CL-1 has ROS 1 only. For research and multi-vendor robotics stacks, native ROS 2 is the strongest signal of ecosystem maturity.
Does Forerunner K2 or CL-1 use LiDAR?
CL-1 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.
