Frequently asked questions
Which is cheaper: G1 or Forerunner K2?
G1 is cheaper at $13,500 vs $34,800 for Forerunner K2. Note that lower price does not imply lower total cost of ownership — see the TCO calculator on the Explore page for utilisation-adjusted figures.
Which has higher payload: G1 or Forerunner K2?
Forerunner K2 rates a higher payload at 15 kg vs 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 Forerunner K2 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 Forerunner K2?
G1 has ros2; Forerunner K2 has no ROS support. For research and multi-vendor robotics stacks, native ROS 2 is the strongest signal of ecosystem maturity.
Does G1 or Forerunner K2 use LiDAR?
G1 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.
