SunCubes Srl
"Wireless Power, Wherever You Need It"
Milan deep-tech startup developing laser-based optical wireless power transmission systems for drones, UAVs, and underwater autonomous vehicles.
SunCubes Srl is a Milan-based deep-tech startup founded in 2023 and incubated at ESA BIC Milan through Politecnico di Milano's PoliHub innovation hub. The company was established by five engineers with expertise in aerospace engineering, photonics, laser technology, and advanced optics drawn from Politecnico di Milano, Universita di Pisa, and Universita di Bologna.
SunCubes is developing optical wireless power transmission (OWPT) technology that uses collimated laser beams to deliver electrical energy wirelessly over long distances, eliminating the need for cables, physical landing pads, or human intervention. The core application is continuous in-flight recharging of unmanned aerial systems (UAS), extending drone mission durations far beyond battery-limited flight times.
The flagship product platform, SunCubes Lucy, is designed to deliver 200 W of usable power to a drone receiver over ranges up to 3 km using 500 W of optical laser output. The system incorporates automatic beam pointing and tracking, a patented safety shutoff that interrupts the laser if any obstruction enters the beam path, and an interface mechanically and electrically compatible with standard UAS form factors. In October 2024, SunCubes successfully demonstrated 600-meter power delivery at Leonardo's Venegono facility. The company raised a 1.1 million euro seed round to advance the technology.
In June 2026, SunCubes announced the DEEP LIGHT program — a blue-laser underwater wireless power platform for autonomous underwater vehicles (AUVs) — backed by the Italian Navy through the Polo Nazionale della Dimensione Subacquea (PNS). DEEP LIGHT leverages the blue-green optical window optimized for marine light propagation to enable contactless underwater energy transfer over tens of meters, supporting naval surveillance and offshore operations. SunCubes partnered with NUBURU and Lyocon for blue-laser subsystem development. SunCubes represents Italy's emerging capability in laser-based power beaming for both aerial and submarine robotics applications.

Hyundai's Louisiana Steel Mill to Supply Materials for Robots and SpaceX Rockets
Hyundai Motor Group Executive Chair Chung Euisun announced that steel from the upcoming Hyundai Steel mill in Louisiana could be utilized beyond automotive applications, potentially in Atlas humanoid robots and SpaceX rockets. This vision was shared during the groundbreaking ceremony for the Hyundai-Posco Louisiana Steel plant, which will initially focus on automotive steel production. The $5.8 billion electric arc furnace facility is set to be Hyundai Steel's first production base in the U.S., with an annual capacity of 2.7 million metric tons, including 1.8 million tons dedicated to automotive steel and 900,000 tons for other uses. Chung's comments reflect a long-term strategy to diversify the mill's output, aligning with Hyundai's plans to deploy Atlas robots in U.S. manufacturing operations by 2028. Looking ahead, Hyundai is cautious about deploying Atlas within the steel mill, emphasizing the need for extensive testing. Chung also highlighted the company's efforts to enhance Atlas' development by reorganizing its structure to accelerate technology adoption and improve capabilities in critical components like actuators and grippers.

XDOF Engages in Series B Funding Talks at $1.2 Billion Valuation
XDOF, a startup specializing in real-world teleoperation data for training robots, is in advanced discussions for a Series B funding round, aiming for a valuation of approximately $1.2 billion. The funding is reportedly led by 8VC, following the company's rapid growth and annualized revenue nearing $50 million. The significance of this funding round lies in XDOF's role in addressing a critical bottleneck in robotics: the lack of large-scale real-world datasets. Co-founded by UC Berkeley researchers Philipp Wu and Fred Shentu, XDOF aims to provide outsourced data solutions for the robotics industry, similar to what Scale AI offers for AI applications. Looking ahead, XDOF is set to release what it claims is the largest collection of high-quality robot training data, known as ABC, in collaboration with UC Berkeley's AI Research lab. The startup is also planning to expand its workforce of data collectors globally, which will enhance its capabilities in generating essential training data for robots.

Monumental's CEO Discusses Robotics Potential in Construction Industry
In a recent episode of Lexicon, Salar al Khafaji, founder and CEO of Monumental, highlighted the overlooked potential of robotics in the construction industry. He emphasized the challenges of deploying autonomous robots on unpredictable building sites and the need for specialized machines to address rising construction costs and housing shortages. Al Khafaji pointed out that construction has not received the technological attention it deserves, despite its significant economic and social impact. He believes that the industry is vast and underappreciated by tech founders, which is why he pivoted from data visualization to focus on tangible impacts in construction. Monumental has developed autonomous robots capable of transporting materials and constructing brick walls on commercial sites. However, al Khafaji noted that real-world deployment presents unique challenges, such as varying environmental conditions that affect sensors and computer vision systems.

Pentagon Reports 11 Percent Cost Increase for F-35 Joint Strike Fighter Variants
The Pentagon has announced that the costs for all three variants of the F-35 Joint Strike Fighter are rising by approximately 11 percent. The average flyaway cost for the F-35A has increased to $92 million for production lots 18 and 19, up from $82.5 million, while the F-35B and F-35C have also seen price hikes to $121.4 million and $110.8 million, respectively. This increase in costs is significant as it reflects ongoing challenges faced by the F-35 program, including inflation, rising raw material prices, and supply chain issues. Lockheed Martin, the manufacturer, has indicated that these factors have contributed to the rising costs, which are projected to exceed $50 billion over the program's lifespan due to upgrades and increased spare parts. Looking ahead, the Pentagon plans to acquire 148 aircraft each in lots 18 and 19, totaling 296 aircraft. The F-35 program continues to evolve with modernization efforts, including enhancements to the engine and a new power management system, although some upgrades are behind schedule.

Tesla Reveals New Details About Cybercab, Including Age Restrictions for Passengers
Tesla's recent private event for the Cybercab showcased a stark departure from its typical large-scale launches, with CEO Elon Musk notably absent. The Cybercab promises to be a fully autonomous vehicle utilizing cameras and AI, but details were sparse, primarily shared through PDFs and updates to the 'Robotaxi' app. A significant point of contention is the restriction on minors under 13 from riding in the Cybercab, while those aged 8 to 17 can use the Model Y SUVs, albeit with adult supervision. The implications of these restrictions highlight Tesla's cautious approach to safety amid ongoing investigations by the National Highway Traffic Safety Administration into the Cybercab's rollout. The absence of standard child seat anchors in the Cybercab raises concerns, especially as Tesla aims to ensure the safety of all passengers. The vehicle's safety features, including automatic crash responses, are designed to mitigate risks, but the decision to limit child passengers reflects the company's hesitance to fully embrace its autonomous technology in all scenarios. Looking ahead, Tesla must navigate regulatory scrutiny and public perception as it seeks to validate the safety of the Cybercab. The company's commitment to innovation in autonomous driving will be closely monitored, particularly in light of recent recalls related to electronic door latches. No further timeline was disclosed at the time of publication.
