Pros and cons at a glance
GR-2
Pros
- Shipping to customers (verified commercial availability)
- 53 degrees of freedom — full-body articulation
Cons
- Unit price not publicly disclosed (quote-on-request or enterprise-only)
- Low rated payload (3 kg) — research or light-handling tasks only
- Short runtime (120 min) — frequent recharging or battery swaps
A2
Pros
- Shipping to customers (verified commercial availability)
- Ships with LiDAR for robust depth sensing in low-light environments
- 40 degrees of freedom — full-body articulation
Cons

Frequently asked questions
How do GR-2 and A2 compare on price?
GR-2: ~$150,000+, enterprise only; no US sales channel. A2: $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: GR-2 or A2?
A2 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.
Are both GR-2 and A2 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: GR-2 or A2?
GR-2 has ROS 1 only; A2 has ros2. For research and multi-vendor robotics stacks, native ROS 2 is the strongest signal of ecosystem maturity.
Does GR-2 or A2 use LiDAR?
A2 ships with LiDAR for depth sensing; GR-2 does not. LiDAR adds cost and complexity but improves obstacle detection in low-light or low-contrast environments.
