Humanoid robots with cutting-edge technology to shine at fighting competition

The world's first robot fighting competition will open on Sunday in Hangzhou City of east China's Zhejiang Province, highlighting humanoid robots equipped with cutting-edge technologies.

The event, China Media Group (CMG) World Robot Contest: Mech Combat Arena Competition, will be livestreamed globally.

The competition is set in the Olympic Sports Center in Hangzhou. The participating humanoid robots not only master fighting skills such as straight punches, hooks, and side kicks, but can also stand up quickly after falling to the ground. 

Sun Baoyan, marketing manager of Hangzhou-based tech startup Unitree Robotics, one of the developers of the robots, said that these moves are extremely challenging for the robot's balance ability, reaction speed, endurance, and other factors.

"Taking a leg swinging action as an example, the motion control program needs to first analyze the various sensors inside the robot, so that it can sense the state of its body in real time, and then mobilize the motors of each joint to complete such a set of actions. This series of analyses are achieved in milliseconds," Sun said.

A greater challenge for the developers is to solve problems such as robot stability, endurance and heat dissipation in high-intensity confrontations.

The competition mainly consists of two parts: exhibition matches and competitive matches. On the eve of the event, both developers and robots are undergoing high-intensity skill training every day.

"We need to add a lot of fighting-related actions to the robot, all of which require special optimization. At the same time, you can see that our robot has a very strong anti-fall capability, thanks to the large amount of optimization work we have done in motion control algorithms," said Wang Qixin, a board member of Unitree Robotics.

All robots used in this competition adopt domestically developed core technologies. In addition to professional referees and commentators, experts in related fields will be invited to the competition site to deeply analyze the robots' every move, presenting a feast of technology and vision for the audience.

"We have adopted a lot of new technologies in camera settings and technical applications, including free view, AR, VR, and online packaging, trying to use more stylized lenses to make each robot very vivid (in the livestreaming) and make their performance in the matches more infectious. We also hope to further explore the capabilities of humanoid robots through such live broadcasts," said Jiang Hua, chief technical director of the event.

A Chinese envoy on Thursday issued a sharp warning over Japan's nuclear ambitions at the United Nations (UN), accusing Japan of challenging international red lines and urging the Japanese government to clarify its stance and abandon re-militarization.

At the UN Security Council meeting on non-proliferation on the Korean Peninsula, Xu Feng, counselor for the Disarmament Division at China's Permanent Mission to the UN, confronted Japan's recent actions and rhetoric regarding nuclear weapons.

Citing legally binding documents like the Cairo Declaration, Potsdam Proclamation, and the Japanese Instrument of Surrender, Xu stressed that Japan must be fully disarmed and is prohibited from maintaining any capability for rearmament.

"As a non-nuclear-weapon state to the Treaty on the Non-Proliferation of Nuclear Weapons, Japan must abide by its international obligations to not accept, not manufacture, not possess, and not proliferate nuclear weapons," said Xu.

The Chinese side expressed grave concern over Japan's technical status as a recognized "nuclear threshold" state, possessing reprocessing technology, operational facilities, and storing plutonium far beyond civilian energy needs, giving Japan the capability for a rapid "nuclear breakout."

Xu highlighted recent disturbing signals in Japan's nuclear policy, noting that in November 2025, the Japanese prime minister publicly questioned whether the country's Three Non-Nuclear Principles would be maintained amid security policy revisions. In December, a senior official at the prime minister's office reportedly stated that "Japan should possess nuclear weapons."

Xu pointed out that these remarks reveal an ambition among Japanese right-wing forces to challenge the international order. Japan must give a formal, top-level clarification on its nuclear policy and halt all steps towards re-militarization, he said, adding only then can international concerns be truly addressed.
