Swarming magnetic micro/nanorobots hold great promise for biomedical applications, but at present suffer from inferior capabilities to perceive and respond chemical signals in local microenvironments. Here we demonstrate swarming photonic-crystal microrobots (PC-bots) capable of spontaneously performing on-the-fly visual pH detection self-regulated drug delivery by perceiving changes. The PC-bo...

This paper first defines a class of estimation problem called simultaneous navigation and characterization (SNAC), which is superset localization mapping (SLAM). A SNAC framework then developed for the Autonomous Nanosatellite Swarming (ANS) mission concept to autonomously navigate about characterize an asteroid including gravity field, rotational motion, 3D shape. The ANS consists three module...
