These super-small drones no longer need a battery

By:

To be a fly on the wall, an observer must be ubiquitous, unobtrusive and quiet. What if, instead, the observer was just a tiny fly-sized robot, independently powered, able to travel like its insect inspiration? That's one possibility from the long line of work on the RoboBee series of miniature flying machines, the latest of which recently flew independently under its own photovoltaic power.

RoboBee is a long-running project of the Harvard Microrobotics Lab and the Wyss Institute for Biologically Inspired Engineering. The end goal is ultimately controlled swarms of insect-sized flying machines, with visions of these swarms performing everything from plant pollination to surveillance. These are ambitious aims, and all have been hindered to this point by a fundamental constraint on the form: the robots are too small to carry batteries.

Much of the flight design uses a tethered power supply, allowing the designers to craft Piezoelectric motors that expand and contract as electrical current passes through the muscle-like membranes. This created wings that could flap and propel the robot upward, but it wasn't until recently that the robot could do it on its own power supply.

RoboBees are smaller than any drone currently employed by the U.S. military, minute enough to make the palm-sized Black Hornet feel gargantuan. Without a sensor payload, it'd be a novelty, but the military has already invested in cheap, expendable sensor-carrying drone gliders for tasks such as meteorological data collection. Should this power supply enable RoboBees to support a meaningful sensor package, they could be used in a similar fashion, scattered as sensors that can flap their way into a new position.

Holding six solar power cells on a stick, and with a second set of wings, the vehicle successfully flew under its own power, even if only for the briefest of moments. The researchers' documentation of their project was published in scientific journal Nature June 26, appearing under the title “Untethered flight of an insect-sized flapping-wing microscale aerial vehicle.”

The whole RoboBee weights 259 milligrams, or less than a paperclip, and under special lights was able to generate enough lift to support an additional payload of 70 mg, which could be used for lightweight sensors, control electronics, or larger power supply in the future. Fitting sensors to a craft the small is likely a challenge, but also essential for the promise of the device.

There is also the small matter that, even using photovoltaic cells, the robot needs an alien sun to fly.

“The Robobee X-Wing needs the power of about three Earth suns to fly, making outdoor flight out of reach for now,” stated the summary from Harvard's School of Engineering and Applied Sciences. “Instead, the researchers simulate that level of sunlight in the lab with halogen lights.”

Should the sensors exist, and the device become capable of outdoor flight, microrobotics could become a ubiquitous part of modern life, performing functions alongside insects and relaying sensor information back as an unseen intelligence platform.

  • Why defense firms need to get systematic about M&A — big and small

    Why defense firms need to get systematic about M&A — big and small

    By: Eric Chewning and Frank Coleman III After years of growth, defense budgets will likely flatten (or decline). In such a financial environment, the U.S. Department of Defense will consider trade-offs between funding modernization, sustaining legacy equipment and preserving force structure. These hard choices will be informed by the DoD's strategic acquisition priorities, which will likely continue to reflect the need for innovation around leading-edge capabilities in areas like space, C5ISR, long-range precision fires, unmanned vehicles and artificial intelligence. To support these evolving mission requirements, the defense industry will need to ensure the industrial base is able to deliver technological advantage. This requires attracting world-class talent as well as the necessary financial capital to operate global industrial enterprises. Attracting these resources requires continued value creation through growth and return on invested capital improvements. But in a down budget environment, where is this growth to come from? While many will think organic growth is the best value-creating option (and often is), the answer also lies in augmenting a classic portfolio strategy with a systematic approach to transactions. Mergers and acquisitions are a proven growth accelerant for defense companies, and have generated superior shareholder returns and greater resilience for companies that have pursued it systematically. At first glance, this may simply seem like an obvious description of recent history. The aerospace and defense sector, after all, has seen rapid consolidation in the last five years, with deals worth $358 billion struck between 2015 and 2019, three times the total between 2010 and 2014. The problem for defense companies looking for more of the same is that this wave of consolidation now appears to have run its course. The combined market value of the top five defense hardware players is now more than four times that of the next five; so even as further mega-deals are theoretically possible, they will be increasingly difficult to execute, underscoring the value of programmatic M&A. Distinct from selective or organic deal-making approaches, programmatic M&A involves a company conducting two or more small or midsized deals per year, with an aggregate value greater than 15 percent of its market capitalization over five years, that align with their overall corporate strategy (which is hopefully linked to the “fast streams” of growth in the budget (see exhibit below)). These deals get choreographed around a specific business case, such as scaling or integrating vital digital capabilities, and are rooted in a disciplined appraisal of transactions. In the defense industry, programmatic M&A should be deployed against a strategy supported by the customer's need for innovation, lower costs and better mission outcomes for the war fighter. Our analysis shows that over the last decade, few defense companies took a programmatic approach to M&A. Those who did outperformed their peers in total shareholder returns by 10.4 percent. M&A was also an important key to resilience during the last defense spending downturn in 2007-2011: The top quintile of outperforming companies, as well as optimizing cash and flexing capex, used it as an opportunity to grow less cyclical parts of the business and build digital capabilities. Defense companies may be deterred by the current market environment, featuring stretched valuations, competition from institutional capital and a squeeze on mid-tier players. They may be cautious about the challenge of integrating smaller nondefense acquisitions into company processes and culture — a process that is easier to get wrong than right to be sure. The very complexity of these circumstances creates opportunities for bold players to differentiate themselves from their peers, align their strategies with national defense priorities and add significant value for shareholders. When done well, programmatic M&A can form a central pillar of their growth strategy. With a proactive approach to deal sourcing, holistic diligence, and in-house execution and integration expertise, companies can establish M&A as a critical capability and avoid the risks of reactive, one-off projects. In the challenging environment that confronts the defense industry today, those who act boldly will succeed in creating enduring businesses that can adapt to the evolving needs of the national defense. Eric Chewning and Frank Coleman III are partners at McKinsey and Company. Chewning previously served as chief of staff in the Office of the Secretary of Defense, and before that as the Pentagon's industrial chief. https://www.defensenews.com/opinion/commentary/2020/11/16/why-defense-firms-need-to-get-systematic-about-ma-big-and-small/

    Romania set to choose four new corvettes, frigate upgrade

    Richard Scott, London and Luca Peruzzi, Genoa - Jane's Navy International Romania's Ministry of Defence is nearing a decision on the procurement of new multirole corvettes after receiving final bids at the beginning of October from Damen Schelde Naval Shipbuilding of the Netherlands, Italy's Fincantieri, and France's Naval Group. The EUR1.6 billion (USD1.85 billion) programme covers the acquisition of four corvettes, as well as the combat system modernisation of the Romanian Navy's two ex-UK Royal Navy Type 22 frigates Regina Maria and Regele Ferdinand . A source selection is scheduled for 26 October, although industry sources suggest this could slip by a number of weeks. Romania's requirement calls for a 2,500-tonne class multipurpose ship with capabilities across anti-submarine warfare, anti-surface warfare, anti-air warfare, electronic warfare, naval gunfire support, and search and rescue. The design is also required to provide aviation facilities suitable for an IAR 330 Puma 10-tonne helicopter and a shipborne unmanned aircraft system. In line with Romanian stipulations for local industry participation, all three contenders are proposing build and in-service support in conjunction with subsidiaries or partners based in country. Romania has asked for the first corvette to be delivered inside three years, with the programme to be completed in seven years. Damen Schelde Naval Shipbuilding is bidding a variant of its SIGMA 10514 design with sister yard Damen Shipyards Galati. To meet the Romanian requirement, Daman has specified a Thales Nederland combat management system (CMS)/sensor fit, the Raytheon Evolved SeaSparrow Missile System and Boeing Harpoon Block II anti-ship missiles. The underwater warfare suite would be provided by General Dynamics Mission Systems-Canada. Fincantieri, which owns the Vard Braila and Tulcea shipyards in Romania, is offering a customised variant of the Abu Dhabi corvette previously built for the United Arab Emirates. It is likely that Vard Braila would be the focal point for both construction and in-service support if Fincantieri is selected. https://www.janes.com/article/83937/romania-set-to-choose-four-new-corvettes-frigate-upgrade
