03 Jan 18. MantaDroid could be the wet, electric, flapping robotic sea scout of the future. Consider the manta. The flat, slick body, at home on the ocean’s surface or hiding in the muck of the ocean floor; the subtle movement, flapping through water. The ubiquity of rays, from smaller variants to the massive mantas, in oceans the world around. The manta is a fascinating creature, and so it should come as no surprise that the manta also makes a fascinating body for an underwater robot.
Designed by researchers at the National University of Singapore, the MantaDroid is a manta-inspired robot that propels itself through the water by flapping two flexible wings, and letting fluid dynamics take care of the rest. Each wing is powered by only a single electrical motor each, so the machine has efficiency as well as a snazzy appearance going for it. The robot is small: just shy of 14 inches long and two feet wide. And it’s also light, with the simple body weighing in at only 1.5 pounds. It moves at about 1.6 mph, or twice its body length per second, but what’s really impressive is that it can operate for up to 10 hours.
What makes the robot relevant here, though, is not just its efficient motion body or animal-inspired body. What’s relevant is that the MantaDroid is designed to be a future underwater surveillance platform.
From the National University of Singapore:
MantaDroid makes a promising alternative to traditional propeller-based thrusters used in conventional AUVs, and could potentially operate for a longer range. Like the real manta ray, MantaDroid also has a flat and wide body that can accommodate a range of sensors and be utilised for different purposes such as studying marine biodiversity, measuring hydrographic data and performing search operations.
Putting sensors in an animal-shaped body, especially one that can efficiently navigate the ocean for hours at a time, would make a pretty inconspicuous platform for whoever used it. While the researchers focus on the scientific and public safety aspects of the MantaDroid, the platform would also make a captivating military asset, especially if it could find a way to recharge while out at sea. (There is also the ethical considerations of a surveillance tool disguised as a vulnerable species, and what sort of second-order consequences that might entail).
Military dreams of ghost rays will have to wait for further testing. The next steps for the robot are testing at different depths and withstanding currents. Still, it’s not hard to imagine a future where robot rays scout the shallows of an unfamiliar coast days before humans follow, the gentle flaps of robot flippers on sand masking footsteps.

02 Jan 18. AeroVironment, Inc. (NASDAQ: AVAV), a global leader in unmanned aircraft systems (UAS) for both defense and commercial applications, today announced the formation of a joint venture to develop solar-powered high-altitude long-endurance, or HALE, UAS for commercial operations. This category of UAS is also referred to as high-altitude pseudo-satellites, or HAPS. The joint venture will fund the development program up to a net maximum value of $65,011,481. The joint venture, HAPSMobile, Inc., is a Japanese corporation that is 95 percent funded and owned by Japan-based telecommunications operator SoftBank Corp. and 5 percent funded and owned by AeroVironment, Inc. AeroVironment is committed to contribute $5m in capital for its 5 percent ownership of the joint venture, and has an option to increase its ownership stake in HAPSMobile up to 19 percent at the same cost basis as its initial 5 percent purchase.
“This is a historic moment for AeroVironment. For many years, we have fully understood the incredible value high-altitude, long-endurance unmanned aircraft platforms could deliver to countless organiza
