ThayerMahan
US maritime defense company providing autonomous undersea surveillance, acoustic intelligence, and counter-UUV systems (Outpost, SeaPicket, SeaGuard) for.
ThayerMahan, Inc. is a maritime defense technology company founded in 2016 and headquartered in Groton, Connecticut — the historic home of U.S. submarine forces. The company was co-founded by retired U.S. Navy Vice Admiral Michael Connor, former commander of U.S. submarine forces, along with Navy veteran Richard Jude Hine and innovator John Kao. ThayerMahan takes its name from Alfred Thayer Mahan, the influential 19th-century naval strategist and historian who argued that maritime dominance was central to national power.
The company specializes in persistent autonomous undersea surveillance, delivering scalable acoustic intelligence solutions to defense and government customers. Its core products include the SeaPicket fixed hydrophone array system and the Outpost mobile surveillance platform, both of which operate autonomously for extended periods using renewable energy sources and require minimal human intervention. These systems use advanced passive acoustic sonar and fourth-generation beamforming technology to detect, classify, track, and localize underwater contacts including submarines, unmanned underwater vehicles (UUVs), and surface vessels.
ThayerMahan has expanded its technical capabilities through acquisitions, including the purchase of Ocean Acoustical Services and Instrumentation Systems (OASIS). The company has demonstrated its technology in partnership with NOAA for detecting illegal, unreported, and unregulated (IUU) fishing activity, and has partnered internationally — including with Australian firm Ocius — to develop autonomous undersea warfare capabilities for AUKUS nations. In 2026, ThayerMahan shipped its first SeaPicket system to an international defense customer and opened a dedicated array manufacturing facility in Groton to scale production.

EPFL and NYU Develop Scalable Robotic Fish for Diverse Aquatic Environments
A team from EPFL and NYU has introduced ScaFi, a scalable robotic fish designed to adapt to various aquatic environments. Unlike traditional propeller-driven vehicles, ScaFi mimics the swimming motion of fish, allowing it to navigate shallow waters and dense vegetation without disturbing wildlife. The significance of ScaFi lies in its ability to maintain swimming efficiency across different sizes, which could reduce the engineering effort required for aquatic robots. The research highlights the importance of adaptable tools for environmental monitoring, as ecosystems vary greatly in size and complexity. Future developments will focus on understanding the energy efficiency of ScaFi as it scales, as initial tests revealed challenges with larger models. The team aims to explore whether the energy performance can be improved alongside the swimming capabilities of the robotic fish.
Chen Pu of Yuan Ke Vision Discusses Transitioning Robot Training Data from 2D to 4D with High Precision
On September 23, Chen Pu, Vice President of Product Development at Yuan Ke Vision, highlighted the importance of high-quality real data for robot training during a seminar in Beijing. He emphasized the need to elevate data from 2D to 4D and improve precision from centimeter to sub-millimeter levels to build a robust 4D data foundation for robotics. This transition is crucial as the industry faces challenges such as weak model generalization and inadequate scene adaptability. Chen noted that current training methods often rely on limited 2D video data, which fails to capture the complexities of three-dimensional space and temporal changes, hindering robots' ability to understand and interact with their environments effectively. Looking ahead, Yuan Ke Vision aims to address these challenges by developing new data collection and training paradigms that enhance dimensionality, enrich modalities, and improve precision. Chen pointed out that while video data serves as a foundation, it is often too simplistic, and the lack of tactile data remains a significant gap in the industry.

Robot Dogs Use Insect-Inspired Movements to See Through Obstructions in 17 Milliseconds
A collaborative team from Johannes Kepler University Linz, Free University of Bozen-Bolzano, University of Trento, and University of Sussex has developed a method for robot dogs to mimic insect movements to enhance their visual perception. By performing rhythmic lateral movements, akin to the 'peering' behavior observed in insects like locusts, these robots can effectively see through obstructions such as foliage and debris. This innovation is significant as it addresses a common challenge faced by exploration robots in environments cluttered with obstacles that hinder visual sensors. The research establishes a connection between the peering motion and synthetic aperture sensing, allowing the robots to create a virtual aperture that enhances background signals while blurring out obstructions. Future developments to watch include the potential applications of this technology in various environments, including forests and disaster sites. The research indicates that the synthetic aperture technique is most effective at around 50% obstruction density, suggesting a promising avenue for improving robotic vision in complex terrains.

Mondo Robotics' Beni: A Tumbling Robot Camera with Significant Obstacle Avoidance Issues
Mondo Robotics has introduced Beni, a small bipedal robot designed to capture and record video while following users. Equipped with a built-in camera and sensors, Beni can perform tricks like flips and roll while tracking specified objects via an app. However, after several weeks of testing, reviewers found Beni's obstacle avoidance capabilities severely lacking. The importance of Beni lies in its potential as a fun companion for personal activities like sports and pet video recording. Despite its interesting features, the robot struggles significantly with obstacle avoidance, often losing track of its target in cluttered environments. Reviewers noted that even in open spaces, Beni failed to navigate around obstacles effectively, which detracts from its overall usability. Moving forward, it will be crucial to monitor Mondo Robotics' efforts to improve Beni's obstacle avoidance technology. Currently priced at $599, the robot's value is questionable given its primary flaw. If Mondo can address these issues, Beni could become a more appealing option for users engaged in various activities, but until then, recommendations are limited.
