One of the challenges to life in space is electricity. It’s a way to keep humans comfortable and operate robots when there is no built-in power outlet and solar power is not always an option.
Currently led by space technology company Astrobotic, a team of organizations including the University of Washington and the UW Spinout WiBotic is $ 5.8 million to develop a line of lightweight, ultra-fast wireless chargers that can assist both humans and robots. I received the contract. Live and work on the moon. This agreement is part of NASA’s call for proposals at a turning point.
A prototype of wireless charging has existed since 2011, but this new magnetic resonance-based power supply system is the first in space.
Wireless charging in space involves a unique set of issues, such as how to prevent the metallic iron contained in the lunar dust (or lunar regolith) from interfering with the charging connection. The University of Washington received $ 440,000 from this deal to study how the moon’s regolith affects wireless power transmission.
“Moon dust is very fine and tends to adhere to the surface because it is charged. The UW team tackles the question of basic research on how the particle size and composition of dust affects power transfer efficiency. “We are,” said Joshua Smith, a senior researcher at UW, who is a professor of both Paul G. Allen’s Faculty of Computer Science and Engineering and Department of Electrical Engineering. Computer engineer. “We plan to take an approach that is a hybrid of science and engineering. We will develop synthetic moondust that matches known related characteristics, which is the worst case of our wireless power transmission system. Represents.
“Our work is the basis for the engineering requirements of the other members of the team. This helps answer questions such as: How much more to overcome the expected heat loss. Do you need to transfer power, or how much cooling capacity do you need to incorporate into your system to remove the heat generated by the moon dust? “
Developed in collaboration with NASA Kennedy Space Center, Astrobotic’s CubeRover is the first space technology to integrate with a wireless charging system. Part of NASA’s TippingPoint agreement will fund the development of CubeRover’s intelligent autonomous navigation system. This allows for accurate navigation even when GPS is not an option. Equipped with CubeRover (and other planetary roving technologies), it allows you to find and power the charging dock multiple times to survive the 14-day moonlit night.
Astrobotic certifies the entire system, test engineering, and flight model space, and leads the integration of a multi-kilowatt ultra-fast wireless charging system designed by CubeRover and WiBotic. WiBotic also provides engineering, mechanical and electrical design support.
Ben Waters, CEO of WiBotic, said: “These rover require easy and reliable power access in environments with highly abrasive dust and harsh temperatures.” We work with Astrobotic and our team. We look forward to providing a flexible and durable charging station that powers a variety of manned and unmanned lunar rover. “
This wireless charging technology can be quite useful not only on the Moon, but also on Mars, orbit, and other critical space applications. Future teams will be able to extend wireless technology to a variety of assets such as lunar rover, power tools and flight systems. Base stations, power receivers, and CubeRover flight units will be delivered to NASA in 2023 via the Commercial Lunar Payload Services program for inclusion in the next lunar mission.
