KAIST HOUND 1 is a fast, strong research quadruped built at the Dynamic Robot Control and Design Lab of KAIST in South Korea. Its drivetrain was designed with mixed-integer optimization of the gear train and motor heat limits, so the legs can deliver high torque and high speed without overheating. A single walking controller trained entirely with reinforcement learning let it run 100 metres from a standing start in 19.87 seconds, a Guinness World Record for the fastest quadruped robot. It also walks long distances, climbs slopes and steps over tall obstacles, which makes it a leading platform for legged-locomotion research.

Frequently Asked Questions

Get answers to common questions about this robot

Q1. What is the robot dog KAIST HOUND 1, and what problem does it solve?

KAIST HOUND 1 is a research quadruped from KAIST in South Korea. It was built to prove that a legged robot can combine very high speed, strong joints and long-distance efficiency, which most robot dogs trade off.

Q2. What are the main capabilities and key features of KAIST HOUND 1?

It runs faster than any other quadruped robot on record, walks long distances, climbs slopes and steps over tall obstacles. Its optimized gear train and a locomotion controller trained with reinforcement learning make the movement fast, stable and efficient.

Q3. Who is KAIST HOUND 1 built for, and which industries benefit from it?

It is built for robotics researchers and universities studying fast legged locomotion, as well as defense and field-robotics programs that need a high-performance walking platform.

Q4. Is KAIST HOUND 1 a commercial product or a research prototype?

It is a research prototype, not a retail product. Its design and test results are published for other research teams to learn from and reuse.

Q5. Is KAIST HOUND 1 currently available for purchase?

No. It is not sold; KAIST uses it in its own research, but the lab shares its design details and a simulation model for other researchers.

Q6. How does KAIST HOUND 1 perform in real-world environments and rough terrain?

It was tested on outdoor tracks, slopes and obstacles as well as on a treadmill. The record run shows it holding a fast, steady gallop outdoors, and long walks show it stays efficient over distance.

Q7. When was KAIST HOUND 1 announced or officially launched?

The design was presented at a robotics conference in 2022, and the world-record run followed in October 2023.

Q8. How does KAIST HOUND 1 compare to other quadruped robot dogs?

Most robot dogs focus on carrying sensors or payloads at modest speeds. HOUND 1 is tuned for speed and agility, so it is closer to a sprinter than a patrol robot.

Q9. Can KAIST HOUND 1 be customized with add-ons or third-party tools?

Because it is a lab platform, KAIST can change its controller and hardware, and the published simulation model lets other teams test their own ideas on a virtual copy.

Q10. What is the future roadmap or planned upgrades for KAIST HOUND 1?

KAIST has already built a follow-up, HOUND 2, which the lab describes as faster and able to outrun a human, so the line continues toward quicker and tougher legged robots.
