Efficient Visual Ego-Motion Estimation for Agile Flying Robots

Micro air vehicles (MAVs) have shown significant potential in modern society. The development in robotics and automation is changing the roles of MAVs from remotely controlled machines requiring human pilots to autonomous and intelligent robots. There is an increasing number of autonomous MAVs involved in outdoor operations. In contrast, the...

Architected Cementitious Cellular Materials Towards Auxetic Behavior

In recent years, the rapid development of digital fabrication technology has substantially boosted the research of architected cellular materials. Among them, the auxetic materials are a distinct type for their unusual deformation behavior: negative Poisson’s ratio. When loaded longitudinally in compression, in contrast to conventional materials...

On-chip integration of Si/SiGe-based quantum dots and electronic circuits for scaling

With continuous breakthroughs in quantum science and technology in recent years, the development of quantum computers is moving from pure scientific research to engineering realization. Meanwhile, the underlying physical structures also develop from the initial single qubit to multiple qubits or medium-scale qubit registers. Since qubits are...
