What it is
A wheel-legged security and inspection robot on a mid-size platform
Aero-W starts with the Unitree A2-W and adds Stokes Robotics secondary development on top. The A2-W puts wheels on the legs of the A2, rolling across open ground with 20 to 25 kg on board and using its legs to climb stairs, and Aero-W arrives set up for security and inspection work.
Aero-W is offered in Standard and Pro configurations. The Pro adds a second LiDAR, GPS, 4G, and a high-performance expansion dock for SLAM mapping and autonomous navigation.

Questions
Aero-W FAQ
Aero-W is built on the same A2-W configurations and includes Stokes Robotics secondary development, set up for security and inspection work. The Unitree A2-W is sold without Stokes development.
SIRAS is the Stokes Robotics Security and Inspections Robotic Assistant System. Aero-W is most commonly used for security and inspection work, including SIRAS.
Aero-W is built on the wheel-legged A2-W, which adds wheels to the legs, uses 16 degrees of freedom instead of 12, weighs about 52 kg with battery, and reaches up to about 6 m/s. Aero is built on the legged A2, which weighs about 37 kg with dual batteries.
About 4 to 5 hours and about 20 km without a load, and about 2.5 to 3 hours and about 12.5 km with a 25 kg load, on the dual-battery system. Each battery charges in about 1 hour.
Yes. We offer onsite setup and training and online training for the people who will run Aero-W, before and after the sale. Both are optional add-ons you can choose at checkout or in your quote request.
