Weight
CaveatSECONDARY SOURCE. The figure appears at KAIST RaiLab, the laboratory that developed the robot - not at Raion Robotics, which sells it. The manufacturer's own page discloses no weight for the robot (only 1.8 kg for a single motor module).
Runtime
CaveatSECONDARY SOURCE, no load condition. The source states 'up to 8 hours of continuous operation' without saying at what load or behavior. The figure is therefore not comparable to Unitree B2's 4 hours at 20 kg.
Max speed
CaveatSECONDARY SOURCE, and the operator is the source's own: 'can reach speeds of up to 6 m/s'. Up to is a ceiling, not an operating speed.

Intended use, per the manufacturer
The manufacturer’s words
Modular payload space supports perception, communication, and mission equipment for patrol, inspection, and research workflows.
RAIBO2 integrates high-output actuators, reinforced mechanical structure, and learning-based control into a field-ready quadruped platform.

L22: 'patrol' is mapped to security and surveillance. WEAKEST of the six: the manufacturer writes neither 'security' nor 'surveillance' about RAIBO2 - only 'patrol', and only once. The university laboratory behind the robot, KAIST RaiLab, writes something different: 'a practical and cost-effective solution for industrial applications' - but RaiLab is not the manufacturer, and their words are not used here.

Notes
- The manufacturer's only technical table describes a single actuator module, not the robot — including a 1.8 kg "weight" that is the motor's, not the robot's. Not used as robot specs.
- The manufacturer's claim that this robot completed a public marathon course is marketing language — no distance or time is stated.
