Mars Exploration with Directed Aerial Robot Explorers

Global Aerospace Corporation (GAC) is developing a revolutionary system architecture for exploration of planetary atmospheres and surfaces from atmospheric altitudes. The work is supported by the NASA Institute for Advanced Concepts (NIAC). The innovative system architecture relies upon the use of Directed Aerial Robot Explorers (DAREs), which essentially are long-duration-flight autonomous bal...

Modular Optimization for Robotic Explorers

Robotic explorers perform multiple tasks and have multiple constraints to optimize. Planning the best sequence of tasks requires information about how a given sequence will affect the constraints and goals of the explorer. Modules for all constraints and goals are created, each one of which evaluates a given plan from its point of view. The resulting values of the modules are then combined in a...

Fast Cartography for Data Explorers

Exploration is the act of investigating unknown regions. An analyst exploring a database cannot, by definition, compose the right query or use the appropriate data mining algorithm. However, current data management tools cannot operate without well defined instructions. Therefore, browsing an unknown database can be a very tedious process. Our project, Atlas, is an attempt to circumvent this pr...

Automated Aircraft Touchdown

In this paper, we explore the challenging and important problem of automated aircraft landing. We created a simulator to be able to perform online experiments in various conditions including stormy weather and starting from off-trajectory starting points. We experiment with a wide range of techniques to learn the optimal flight policy including reinforcement learning, Monte Carlo based dynamic ...

Go long! A touchdown for factor VIII?

The recurrent hemarthroses and resultant crippling hemophilic arthropathy of hemophilia have almost been completely eradicated through aggressive prophylactic therapy with clotting concentrates in the developed world. Quality of life measures now track similar to their unaffected peers and patients engage regularly in sporting activities unimagined in previous generations.1 Prophylaxis for seve...
