Overview, buying status, and research notes

What it isHRP-4 is a humanoid from Kawada Robotics. Humanoid platform in the HRP family Our review focuses on what is published today: size, payload, runtime, mobility, software access, safety claims, and whether buyers can actually purchase or deploy it.
Availability and pricingHRP-4 is currently listed as research platform. Pricing is JPY 26,000,000 reported launch price. That buying status matters because a preorder, pilot, enterprise quote, prototype, or discontinued model means very different things for buyers.
Best fitBased on its published specs and positioning, HRP-4 is most relevant for research, human environment robotics. It should be evaluated as a practical robot for the intended job, not only as a brand name or demo video.
What to watchPublic specifications can change as the manufacturer releases new details. Verify release timing, purchase availability, safety claims, autonomy level, SDK or ROS access, payload, runtime, battery details, sensors, hand design, actuator details, walking speed, and stable manufacturer measurements.
Comparable robotsA useful comparison set for HRP-4 includes Tesla Optimus, Figure 02, Unitree G1, Apollo, Digit, NEO, Phoenix, Walker S, GR-2, Unitree H2. Compare price, availability, height, weight, payload, runtime, DOF, walking speed, hands, software access, service model, and deployment evidence.
Specs that matterHRP-4 has 22 documented specification fields available for review. Specification highlights include Price: JPY 26,000,000 reported launch price; Availability: research platform; Height: 151 cm (1510 mm); Weight: 39 kg; Payload: 0.9 kg per horizontally extended arm reported in HRP comparison; DOF: 34; Actuators: 34 actuators minimum (estimated from total DOF). The important question is whether the published capabilities match the actual work: lifting, walking, sensing, manipulating objects, operating safely, and being supported after deployment.
