Agility Robotics (Amazon)

Apptronik
55
Digit
β
Apollo
ROS2 compatible, Python SDK. Closed source. Limited public docs.
Digit: $250,000. Apollo: Target <$50,000 at scale. Only one of the two has a public unit price; the other publishes a range or enterprise-only terms.
Apollo rates a higher payload at 25 kg vs 16 kg. Payload ratings are vendor claims and do not always include a duty cycle β peak vs sustained payload can differ significantly.
Digit is shipping to customers. Apollo 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.
Digit has ros2; Apollo has no ROS support. For research and multi-vendor robotics stacks, native ROS 2 is the strongest signal of ecosystem maturity.
Digit ships with LiDAR for depth sensing; Apollo does not. LiDAR adds cost and complexity but improves obstacle detection in low-light or low-contrast environments.
