Chinese team sets world record with 116 autonomous underwater drones in swimming pool test
Quick Look
- A Chinese team from Northwestern Polytechnical University and Xian Tianhe Maritime Technologies set a Guinness World Record by deploying 116 autonomous underwater vehicles (TH-618s) in a swimming pool on August 29, 2026.
- The drones performed formation navigation without human intervention for 34 minutes over 500 metres, verified by Guinness officials.

Why It Matters
The test was conducted to demonstrate advancements in autonomous underwater swarm technology, with vehicles operating without human intervention using real-time data for navigation.
Vehicles were deployed in sequence and carried out formation navigation with no human intervention during the test in a swimming pool
A Chinese team has set a world record for the most autonomous underwater drones operating at the same time, deploying more than a hundred of the small robots in a swimming pool test.
The Guinness World Record for “most autonomous underwater vehicles operating simultaneously” was set by a team from Northwestern Polytechnical University in collaboration with Xian Tianhe Maritime Technologies.
The trial involved a swarm of 116 autonomous underwater vehicles – called TH-618s, the university said in a statement on September 24.
It took place on August 29 in a pool measuring 50 metres (164 feet) long and 20 metres (65 feet) wide under the supervision of Guinness World Records officials, who have since certified and posted the record on their website.
The vehicles were deployed in sequence and executed autonomous underwater formation navigation with no human intervention for 34 minutes over 500 metres, relying on real-time data to follow their preset route.
