Overview
Aero at a glance
01
Set up for security
Stokes secondary development configures Aero for security and inspection work, including our SIRAS system.
02
Carries a real load
25 kg effective load, with about 3 hours of walking at that weight.
03
Long shifts
About 5 hours and 20 km of walking without a load, with a dual-bay battery system.

What it is
A security and inspection robot on a mid-size platform
Aero starts with the Unitree A2 and adds Stokes Robotics secondary development on top. The A2 is a mid-size quadruped with a 25 kg effective load and about 5 hours of walking, and Aero arrives set up for security and inspection work.
Aero 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.

Each Stokes package starts with the base robot and the standard hardware the manufacturer ships with it, such as the battery and charger. Stokes Robotics then completes the secondary development for the job the robot will do and has everything set up before delivery. Your quote lists the exact configuration and contents, so your purchasing team knows what's arriving before anything is ordered.
Depending on the robot, you can add onsite setup and training, online operator training, a connectivity package with its own stand-alone network and touch-screen control, a STEMBOTICS curriculum license for classroom programs, or a battery and controller upgrade on select quadrupeds. Tell us which ones your team needs and we'll include them in the same quote.

Questions
Aero FAQ
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.
SIRAS is the Stokes Robotics Security and Inspections Robotic Assistant System. Aero is most commonly used for security and inspection work, including SIRAS.
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.
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.
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 in your quote request.
Aero is sold through a quote, so your configuration, add-ons, and training are confirmed before anything is ordered. Request a quote and our sales team will build it with you. If you only need the robot, the Unitree A2 can be bought online.
