Aero FAQ

What is the difference between Aero and the Unitree A2?

Aero is built on the same A2 configurations and includes Stokes Robotics secondary development, set up for security and inspection work. The Unitree A2 is sold without Stokes development.

What is SIRAS?

SIRAS is the Stokes Robotics Security and Inspections Robotic Assistant System. Aero is most commonly used for security and inspection work, including SIRAS.

How is Aero different from Aero-W?

Aero is built on the legged A2, which weighs about 37 kg with dual batteries and carries a 25 kg effective load. Aero-W is built on the wheel-legged A2-W, which weighs about 52 kg with battery and reaches up to about 6 m/s.

How long does Aero run?

Unitree lists 5 hours and about 20 km of walking without a load, and 3 hours and about 12.5 km with a 25 kg load, on the dual-battery system. Each battery charges in about 1 hour.

Does Stokes Robotics offer setup and training for Aero?

Yes. We offer onsite setup and training and online training for the people who will run Aero, before and after the sale. Both are optional add-ons you can choose at checkout or in your quote request.
