<From the middle of the back row, clockwise: Professor Hae-Won Park, Dongyun Kang (Ph.D. candidate), Hajun Kim (Ph.D. candidate), JongHun Choe (Ph.D. candidate), Min-su Kim (Research Professor)>
KAIST research team's independently developed humanoid robot boasts world-class driving performance, reaching speeds of 12km/h, along with excellent stability, maintaining balance even with its eyes closed or on rough terrain. Furthermore, it can perform complex human-specific movements such as duck walk and moonwalk, drawing attention as a next-generation robot platform that can be utilized in actual industrial settings. Professor Park Hae-won's research team at the Humanoid Robot Research Center (HuboLab) of KAIST's Department of Mechanical Engineering announced on the 19th that they have independently developed the lower body platform for a next-generation humanoid robot. The developed humanoid is characterized by its design tailored for human-centric environments, targeting a height (165cm) and weight (75kg) similar to that of a human. The significance of the newly developed lower body platform is immense as the research team directly designed and manufactured all core components, including motors, reducers, and motor drivers. By securing key components that determine the performance of humanoid robots with their own technology, they have achieved technological independence in terms of hardware. In addition, the research team trained an AI controller through a self-developed reinforcement learning algorithm in a virtual environment, successfully applied it to real-world environments by overcoming the Sim-to-Real Gap, thereby securing technological independence in terms of algorithms as well.
<Developed 'KAIST Humanoid' Lower Body Platform>
Currently, the developed humanoid can run at a maximum speed of 3.25m/s (approximately 12km/h) on flat ground and has a step-climbing capability of over 30cm (a performance indicator showing how high a curb, stairs, or obstacle can be overcome). The team plans to further enhance its performance, aiming for a driving speed of 4.0m/s (approximately 14km/h), ladder climbing, and over 40cm step-climbing capability.
<‘KAIST Humanoid’ Lower Body Platform running>
Professor Hae-Won Park's team is collaborating with Professor Jae-min Hwangbo's team (arms) from KAIST's Department of Mechanical Engineering, Professor Sangbae Kim's team (hands) from MIT, Professor Hyun Myung's team (localization and navigation) from KAIST's Department of Electrical Engineering, and Professor Jae-hwan Lim's team (vision-based manipulation intelligence) from KAIST's Kim Jaechul AI Graduate School to implement a complete humanoid hardware with an upper body and AI. Through this, they are developing technology to enable the robot to perform complex tasks such as carrying heavy objects, operating valves, cranks, and door handles, and simultaneously walking and manipulating when pushing carts or climbing ladders. The ultimate goal is to secure versatile physical abilities to respond to the complex demands of actual industrial sites.
<An Intermediate Result: A Single-Leg Hopping Robot Has Been Developed>
During this process, the research team also developed a single-leg 'Hopping' robot. This robot demonstrated high-level movements, maintaining balance on one leg and repeatedly hopping, and even exhibited extreme athletic abilities such as a 360-degree somersault. Especially in a situation where imitation learning was impossible due to the absence of a biological reference model, the research team achieved significant results by implementing an AI controller through reinforcement learning that optimizes the center of mass velocity while reducing landing impact. Professor Park Hae-won stated, "This achievement is an important milestone that has achieved independence in both hardware and software aspects of humanoid research by securing core components and AI controllers with our own technology," and added, "We will further develop it into a complete humanoid including an upper body to solve the complex demands of actual industrial sites and furthermore, foster it as a next-generation robot that can work alongside humans."
<Key Components of the Directly Developed Robot: (a) Reducer, (b) Motor Stator, (c) Motor Driver, (d) EtherCAT-CAN convert board>
The results of this research will be presented by JongHun Choe, a Ph.D. candidate in Mechanical Engineering, as the first author, on hardware development at 'Humanoids 2025', an international humanoid robot specialized conference held on October 1st. Additionally, Ph.D. candidates Dongyun Kang, Gijeong Kim, and JongHun Choe from Mechanical Engineering will present the AI algorithm achievements as co-first authors at 'CoRL 2025', the top conference in robot intelligence, held on September 29th. ※Paper Titles and Papers: Learning Impact-Rich Rotational Maneuvers via Centroidal Velocity Rewards and Sim-to-Real Techniques: A One-Leg Hopper Flip Case Study, Conference on Robot Learning (CoRL), Seoul, Korea 2025, Dongyun Kang, Gijeong Kim, JongHun Choe, Hajun Kim, Hae-Won Park, arxiv version: https://arxiv.org/abs/2505.12222 Design of a 3-DOF Hopping Robot with an Optimized Gearbox: An Intermediate Platform Toward Bipedal Robots, IEEE-RAS, International Conference on Humanoid Robots, Seoul, Korea, 2025, JongHun Choe, Gijeong Kim, Hajun Kim, Dongyun Kang, Min-Su Kim, Hae-Won Park, arxiv version: https://arxiv.org/abs/2505.12231 This research was supported by research funding from the Ministry of Trade, Industry and Energy and the Korea Institute of Industrial Technology Planning and Evaluation (KEIT) (RS-2024-00427719). ※ Related Video: https://youtu.be/ytWO7lldN4c

KAIST Research Team Develops World’s First Humanoid Pilot, PIBOT
In the Spring of last year, the legendary, fictional pilot “Maverick” flew his plane in the film “Top Gun: Maverick” that drew crowds to theatres around the world. This year, the appearance of a humanoid pilot, PIBOT, has stolen the spotlight at KAIST.
< Photo 1. Humanoid pilot robot, PIBOT >
A KAIST research team has developed a humanoid robot that can understand manuals written in natural language and fly a plane on its own. The team also announced their plans to commercialize the humanoid pilot.
< Photo 2. PIBOT on flight simulator (view from above) >
The project was led by KAIST Professor David Hyunchul Shim, and was conducted as a joint research project with Professors Jaegul Choo, Kuk-Jin Yoon, and Min Jun Kim. The study was supported by Future Challenge Funding under the project title, “Development of Human-like Pilot Robot based on Natural Language Processing”. The team utilized AI and robotics technologies, and demonstrated that the humanoid could sit itself in a real cockpit and operate the various pieces of equipment without modifying any part of the aircraft. This is a fundamental difference that distinguishes this technology from existing autopilot functions or unmanned aircrafts.
< Photo 3. PIBOT operating a flight simulator (side) >
The KAIST team’s humanoid pilot is still under development but it can already remember Jeppeson charts from all around the world, which is impossible for human pilots to do, and fly without error. In particular, it can make use of recent ChatGPT technology to remember the full Quick Reference Handbook (QRF) and respond immediately to various situations, as well as calculate safe routes in real time based on the flight status of the aircraft, with emergency response times quicker than human pilots.
Furthermore, while existing robots usually carry out repeated motions in a fixed position, PIBOT can analyze the state of the cockpit as well as the situation outside the aircraft using an embedded camera. PIBOT can accurately control the various switches in the cockpit and, using high-precision control technology, it can accurately control its robotic arms and hands even during harsh turbulence.
< Photo 4. PIBOT on-board KLA-100, Korea’s first light aircraft >
The humanoid pilot is currently capable of carrying out all operations from starting the aircraft to taxiing, takeoff and landing, cruising, and cycling using a flight control simulator. The research team plans to use the humanoid pilot to fly a real-life light aircraft to verify its abilities. Prof. Shim explained, “Humanoid pilot robots do not require the modification of existing aircrafts and can be applied immediately to automated flights. They are therefore highly applicable and practical. We expect them to be applied into various other vehicles like cars and military trucks since they can control a wide range of equipment. They will particularly be particularly helpful in situations where military resources are severely depleted.”
This research was supported by Future Challenge Funding (total: 5.7 bn KRW) from the Agency for Defense Development. The project started in 2022 as a joint research project by Prof. David Hyunchul Shim (chief of research) from the KAIST School of Electrical Engineering (EE), Prof. Jaegul Choo from the Kim Jaechul Graduate School of AI at KAIST, Prof. Kuk-Jin Yoon from the KAIST Department of Mechanical Engineering, and Prof. Min Jun Kim from the KAIST School of EE. The project is to be completed by 2026 and the involved researchers are also considering commercialization strategies for both military and civil use.

Hubo Completes New Mission at the Winter Olympic Torch Relay
KAIST-born humanoid robot, Hubo, completed its special new mission: carrying the Olympic torch. The Winter Olympics will be held in PyeongChang for two weeks beginning February 9.
On December 11, the final leg of the torch relay in Daejeon for the PyeongChang Olympics 2018 took place inside KAIST. A city known for science and technology hosted special torch relay runners over three days.
Hubo arrived at the campus with Dr. Dennis Hong, a professor from the University of California at Los Angeles, in an autonomous vehicle. Then, Hubo received the flame from Professor Hong. Hubo, a robot developed by Professor Jun Ho Oh from the Department of Mechanical Engineering at KAIST, is best known for being the winner of the DARPA Robotics Challenge in 2015.
Hubo successfully completed its Olympic mission. That is, it had to drill through a wall to deliver the torch to the next runner. After completing the mission successfully, the torch was passed to Professor Oh. He ran a few steps and handed it over to the last runner of the Daejeon leg.
The last runner was Jung Jae Lee, who is a winning team member of the Samsung Junior Software Cup. Lee also had the honor of riding and controlling FX-2 which is another robot developed by Professor Oh for this peace torch relay. FX-2 took a few steps to finalize the relay.
Lee said, “I would like to become an expert in security. As I was riding the robot, I felt every step I took was one step closer to achieving of making major developments in the field of security.
Professor Oh said, “It is meaningful to see humans and robots cooperating with each other to carry out the torch relay.”
The torch relay, participated in by both humans and robots in Daejeon, was successfully completed and the torch headed off to Boryeong, Chungcheongnam-do.

President of Israel visited KAIST on June 9, 2010.
President of Israel, Shimon Peres, visited KAIST today on June 9, 2010 to witness the development of science and technology in Korea and explore ways of establishing collaboration and cooperation with industries and universities between Korea and Israel. President Peres led a delegation consisted of the Israeli Mister of Industry, Trade, and Labor, the Minister of Communication, and 60 business leaders from the top companies in the security, infrastructure, communication, high-tech, and water industries.
Upon their arrival to the campus, the Israeli delegation was greeted by KAIST’s humanoid robot, “HUBO,” and then moved to its branch campus, IT Convergence Campus, for a ride of Online Electric Vehicle (OLEV) that has been developed by KAIST. The OLEV receives the necessary power through the cable lines buried underground, so it can be provided with a constant and continuous supply of electricity while running or stopping.
Between roads and OLEVs is nothing but space. There is no electrical wires intricately crossed underbody of the electric car or above the road. The pick-up equipment installed beneath the body of the electric car collects magnetic fields created around the underground cables, which then converts the filed into electricity. The OLEV’s wireless, non-contact charging system made it possible for a battery currently used for hybrid or pure electric cars on the market to be smaller and cheaper.
President Peres expressed a great interest in the technology applied to the OLVE, quoting, “the OLEV system is indeed very impressive.” He talked about efforts being made in Israel with respect to the development of electric cars. The country plans to replace the conventional transportation system with electric cars by constructing a network of battery exchange stations and roadside charge points which allow the cars to be charged whenever they are parked.
“Despite the different approach taken by the two nations for the development of electric cars, I believe that transforming the automobile industry from combustion engine to electric system is the right direction we should all follow. Without addressing the current transportation system that heavily dependent on natural resources, we will not be able to promote “green growth on a global scale,” added President Peres.
In addition to electric cars, President Peres took up a considerable portion of his time to exchange ideas on how to expand cooperative relations between universities in Korea and Israel, specifically in the area of space, biotechnology, nanotechnology, high-tech, renewable and alternative energy, and the EEWS initiatives that have been implemented by KAIST to find answers to global issues such as climate change and depletion of natural resources. The EEWS stands for energy, environment, water, and sustainability.
In response, the president of KAIST pledged to set up a stronger and greater tie with research universities in Israel, particularly called for more collaboration between KAIST and Technion-Israel Institute of Technology.
Also, the Israeli delegation had a tour for several Korean research and development centers in Daedeok Innopolis, located in the City of Daejeon, which is the 2nd largest science and research complex in Korea.
Shimon Peres, the 9th president of Israel, held many of important government positions in Israel, among other things, Prime Minster and Minister of Defense. He won Nobel Peace Prize in 1994, together with Yitzhak Rabin and Yasser Arafat for the conclusion of a peace agreement, Oslo Accords, between Israel and Palestine Liberation Organization.

"The 2010 Artificial Intelligence Robot War Competition" begins to receive applications
[Event Notice]
“The 2010 Artificial Intelligence Robot War Competition” begins to receive applications
A good opportunity to gauge the intelligence of your robots
“The 2010 Artificial Intelligence (AI) Robot War Competition” will be held in October 2010, and the Competition has been receiving applications from contestants since April 1st. The deadline for the application will be May 31st, 2010.
Qualified contestants must be a minimum of two, but less than six, team members, and they will compete in one of the two fields: System on Chip (SoC) Taekwon Robot and Humanoid Robot (HURO). Winners will be decided based on the intelligence capabilities presented by a robot’s platform that mimics key functions of the human brain.
SoC Taekwon Robot will compete against one another by using a camera installed on its head to recognize visual images, locations, distances, and gestures of the other competing robot.
HURO competition is a new entry begun this year, and winners will be determined in accordance with the robot’s ability to perform given missions and fights. Missions are to go through a track installed with obstacles, recognize colors and shapes of barriers, and knock down barriers to earn scores. Fighting will be performed in the form of a Korean martial art, Tae-kwon-do.
The Korean government has nominated Robotics as one of the key growth engines to develop IT industry and Korean economy. Robotics converge many of different engineering fields, such as machinery, materials, components, and embedded software. In particular, the SoC is an essential technology for Korea to continuously take lead in the semi-conductor industry in the world, which is an important element for robotics.
SoC stands for System on Chip, an integrated chip that assembles various chips and components to be fabricated together on a single chip, instead of building them on a circuit board. The SoC technology has advantages of higher performance, smaller space requirements, lower memory requirements, higher system reliability, and lower consumer costs.
An artificial intelligence SoC robot is autonomous because it can adapt itself to changes in various environments and reach a given goal without constantly receiving external orders.
For details of the event, please refer to the website of www.socrobotwar.org.
