Funded by the Office of Naval Research (ONR) and DEVCOM Army Research Lab. Designed for testing semi-autonomous intervention in environments where human presence is too risky.
At 85 kg (vs. Nadia's 100 kg), Alex uses custom high-power electric actuators instead of hydraulics, enabling battery-powered outdoor operation. Focus shifts from lab-based locomotion research to real-world urban and disaster-response scenarios.
Features advanced control algorithms that allow the robot to maintain balance after being pushed, exhibiting a "human-like" physical resilience in chaotic environments.
Engineered to traverse uneven terrain and climb obstacles using coordinated movements that parallel the athletic capabilities of a human first responder.
Designed to be operated through high-fidelity interfaces that allow a human pilot to see and feel what the robot does, acting as a remote human proxy.
