About
About RAIBO2
RAIBO2 uses in-house motors, reducers and motor drivers combined with reinforcement-learning control trained in Raion Robotics’ simulation environment. Its actuators provide up to 100 Nm of peak torque with low mechanical loss and backdrivability. Learned locomotion policies maintain foot placement and body stability across stairs, raised platforms and uneven outdoor terrain.
The quadruped includes modular payload space for inspection sensors, communications equipment and research hardware. Camera and lidar inputs support autonomous navigation, while an internal RTPS communications system exchanges compressed data over LTE, Wi-Fi and radio links. RAIBO2 is offered for industrial validation, patrol, inspection, research and proof-of-concept deployments.

Timeline
- RAIBO2 completes full marathon without recharging
2024-11-17 - Demonstration - Raion Robotics records RAIBO2 as completing a full marathon without recharging in 4 hours, 19 minutes and 52 seconds. The demonstration is a hard field-mobility signal for long-duration quadruped operation rather than a short lab demo. Research data later reported the 42.195 km run used 1280 Wh from a 2016 Wh battery pack.
