LiSA UAV: Development of Lightweight and Scalable Autonomous UAV Platform for Low-Cost Intelligent Aerial Sensing

Current autonomous drones for aerial sensing are often costly, heavy (typically over 500 g), and require licensed pilots under aviation regulations. This restricts their use for education, research, and small-scale field applications. LiSA UAV addresses this by offering a lightweight (d on a compact 2.5-inch cinewhoop carbon fiber frame. It supports multiple autonomous modes, including Loiter,

Silent Sentry: A Software-Defined Passive Sensor for Counter-Stealth and Battlefield Survivability

What problem does your design idea solve?

On the modern battlefield, a critical dilemma exists: to see, one must emit energy with active radar, which instantly reveals one's position to be jammed or targeted. This makes surveillance a high-stakes gamble. Furthermore, the proliferation of stealth technology has rendered many conventional radar systems obsolete,

Puffer Defense

Individual soldier defense against last-minute drone attacks is now essential on the modern battlefield. Drones are causing a sharp rise in casualties, especially in the Russia-Ukraine war. UN data shows Ukrainian civilian deaths from drone and missile strikes have increased by nearly 50% in early 2025. With over 400,000 Ukrainian and 790,000 Russian military casualties reported,

HexSense: Ballistically Deployed Wireless Sensor Nodes for Future Planetary in-situ Explorations

Current methods for in-situ planetary surface exploration — whether on the Moon, Mars, or beyond — still rely primarily on single, high-cost platforms such as rovers and landers. Rovers, while mobile, are constrained by limited power and the need to avoid hazards, resulting in extremely slow movement (typically a few centimeters per second). As a result,
