Which has higher payload: Astribot S1 or Optimus Gen 3?
Optimus Gen 3 rates a higher payload at 25 kg vs 5 kg. Payload ratings are vendor claims and do not always include a duty cycle — peak vs sustained payload can differ significantly.
Is Astribot S1 or Optimus Gen 3 actually available to buy?
Astribot S1 is shipping to customers. Optimus Gen 3 is in active development without commercial availability. 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: Astribot S1 or Optimus Gen 3?
Astribot S1 has ros2; Optimus Gen 3 has no ROS support. For research and multi-vendor robotics stacks, native ROS 2 is the strongest signal of ecosystem maturity.
Does Astribot S1 or Optimus Gen 3 use LiDAR?
Astribot S1 ships with LiDAR for depth sensing; Optimus Gen 3 does not. LiDAR adds cost and complexity but improves obstacle detection in low-light or low-contrast environments.
