HRP-3
The HRP-3 humanoid robot, developed by Kawada Industries in collaboration with AIST and Kawasaki Heavy Industries, represents a significant advancement in bipedal robotics for harsh environments. Standing at 160 cm tall and weighing 68 kg, it features 36-42 degrees of freedom, enabling complex manipulations and stable locomotion on slippery or uneven surfaces. Designed for disaster relief, construction, and industrial tasks, HRP-3 boasts dustproof and water-resistant construction, allowing operation under heavy rain or dust. Enhanced leg-arm coordination supports carrying heavy loads, while autonomous/remote hybrid control improves task efficiency. Equipped with stereo cameras, gyroscopes, accelerometers, and force sensors, it navigates challenging terrains, recovers from falls, and performs collaborative work with humans. Its robust hardware and advanced software make it a pioneer in practical humanoid applications beyond laboratories.

Frequently Asked Questions
Get answers to common questions about this robot
Q1. What is HRP-3, and what problem is it designed to solve?
HRP-3 Promet Mk-II is a humanoid robot developed jointly by Kawada Industries, Kawasaki Heavy Industries, and AIST. It is designed to operate in adverse environments, addressing challenges in real-world tasks under a NEDO project launched in 2002.
Q2. What are the main capabilities and key features of HRP-3?
HRP-3 features mechanical and structural components to prevent dust or spray penetration, with redesigned wrists and hands for improved manipulation. It builds on HRP-2's bipedal locomotion for rough terrain and self-protection from tipping over.
Q3. Who is HRP-3 built for, and which industries can benefit from it?
HRP-3 was developed as part of Japan's Humanoid Robotics Project for research and practical applications. It targets industries needing robots in harsh conditions, such as construction and manufacturing, according to project collaborators.
Q4. Is HRP-3 a commercial product or still a research prototype?
HRP-3 is a research prototype from the Humanoid Robotics Project, led by Kawada Industries and AIST. It served as a platform for advancing humanoid technology rather than direct commercialization.
Q5. Is HRP-3 currently available for purchase, and when is it expected to ship?
As of 2026, HRP-3 is not available for purchase, having been a project-specific prototype. No shipping timelines were announced, as it preceded later commercial efforts like NEXTAGE.
Q6. How does HRP-3 actually work in real-world environments?
HRP-3 integrates hardware from Kawada, software from AIST, and remote control from Kawasaki for operation in adverse settings. It handles rough terrain and manipulation tasks, with dust-resistant design for practical testing.
Q7. When was HRP-3 announced or officially launched?
HRP-3 Promet Mk-II was announced on June 21, 2007, by Kawasaki Heavy Industries, Kawada Industries, and AIST. It resulted from a five-year NEDO project started in 2002.
Q8. How is HRP-3 different from other robots in the same category?
HRP-3 emphasizes dust and spray resistance plus enhanced hand manipulation, differing from predecessors like HRP-2. It focuses on real-world adverse environments, unlike platforms such as Fujitsu's HOAP series.
Q9. Does HRP-3 require additional development or customization after purchase?
As a research prototype, HRP-3 required software and control integration by project partners. No standard purchase model existed, so customization was inherent to its development process.
Q10. What is the future roadmap or planned upgrades for HRP-3?
Kawada Technologies has refreshed HRP-2 systems and aims to develop advanced humanoids for construction sites. The HRP series informs ongoing efforts toward robots resilient to falls and unstable terrain.
