This report aims to demonstrate the feasibility of building a global 3-D map from multiple UAV robots in a GPS-denied, indoor environment. Presented are the design of each robot and the reasoning behind choosing its hardware and software components, the process in which a single robot obtains a individual 3-D map entirely onboard, and lastly how the mapping concept is extended to multiple robotic agents to form a global 3-D map using a centralized server. In the latter section, this report focuses on two algorithms, Online Mapping and Map Fusion, developed to facilitate the cooperative approach. A limited selection …

Attitude determination and control is one of the most important subsystems on any satellite, allowing the spacecraft to sense and control its orientation while in orbit. Attitude sensing is achieved by measuring the satellite’s acceleration, rotation, and it’s alinement to Earth’s magnetic field. With its orientation determined, a satellite can use one or several different techniques to regulate its motion. One methods is to use of a pseudo-passive system of electromagnets (called magnetorquers) powered at specific times to use magnetic fields generated by the Earth to exert force on the spacecraft, thereby controlling the rotation of the satellite and facilitating …
