SCONE
Hybrid rolling-walking hexapod platform
It runs on flat ground through rotational motion and walks on stairs with six legs — two modes handled by a single sector-shaped frame, with no transformation mechanism.

Figures are measured on SCONE v2.
v1
The body used a parallel-link structure with a sector frame. Legs were too long and actuator torque too low, which limited motion.
v2
We replaced the parallel link with a channel-shaped frame and enlarged the sector frame, reaching 2 m/s rolling, 0.7 m/s walking, and 15+ consecutive steps.
v3 (in development)
We are retuning the sector frame and adding LiDAR plus about four cameras for autonomous navigation. v3 will carry a real AED and run repeated simulated-emergency PoCs on a university campus as the first test bed.
First market
The problem is not how many AEDs exist — it is whether they arrive
Roughly 80,000 AEDs are installed nationwide, yet bystanders actually use one in only 0.74% of out-of-hospital cases. The device is hard to locate, and even when located, it takes time to carry. The four-minute golden window closes in the meantime.

The AED must stop being a device fixed to a wall and become a device that comes to the patient.
Emergency (current)
Carries an AED to reach the patient within the golden window.
Firefighting
Exploring entry reconnaissance and hose-integrated configurations.
Infrastructure inspection
Applied to stairs and confined sections in power generation and substation facilities.
Patrol
Night patrol and anomaly detection in mixed-use facilities.
Same platform in every case — only the payload changes.
