 | This report provides a detailed procedure for interfacing an Atmel SAM7S256 board with a Linux-based PC. The environment and interface are related to a new autopilot project that is designed around the ARM7 architecture used within the U.S. Army Research Laboratory's Vehicle Technology Directorate. An example project is also discussed as a means to see how the environment operates. |

| Presented is an overview of the work accomplished toward the development of a fully autonomous mesoscale hexapod robotic system. A circuit board and mobility system were developed in-house during the summer of 2008 to serve as the first generation of this platform. Much of the attention for this project has been focused on designing the system to be lightweight, small, and computationally capable of autonomous behavior using state-of-the-art embedded electronics ... |

| This report describes a 3-degrees-of-freedom gimbaled platform designed to be used as a hardware in the loop simulator. This platform is designed to aid in the calibration and synchronization of micro aerial vehicles' autopilot components. This platform can also be used as a simulator allowing the autopilot to fly a computer model of the airframe. This allows for the quick and efficient verification of autopilot behavior with different airframes under ... |

| The TCM8230MD is a color complementary metal-oxide semiconductor video camera manufactured by Toshiba. Image resolutions range from 128x96 to 640x480 pixels, with frame rates as high as 30 Hz. Due to high data rates, a powerful microcontroller with an efficient buffering algorithm is required. Because of its small size, mass, power consumption, and cost, this camera has tremendous application to micro-robotic systems. Microcontrollers such as the ARM9 have dedicated hardware ... |

| Autopilots utilizing a single processor allow for smaller, lighter, more cost-effective designs than those using multi-processor architecture. Presented here is a software architecture that allows multiple tasks to operate in a real-time mutually exclusive environment using a single 8-bit processor. This type of architecture will be utilized to create an autopilot using a single processor and sensors. The problem is preventing individual tasks from interfering with one another in a ... |

| There is a critical need to improve the performance and utility of unmanned aerial vehicles (UAVs). Several areas of UAV performance need to be improved for the next generation of UAVS to be used successfully in expanded future combat roles. For example current time aloft is only on the order of an hour or two for electric-powered UAVs. The current generation of UAVs lacks vertical takeoff and landing (VTOL) capability ... |

| A rifle-mounted, boresighted camera and rugged video recorder can be used to determine where the rifle is pointed at the time the trigger is pulled. This information can be collected in exercises simulating close combat to help us better understand how to optimize small arms for this battle space. In this report, we examine issues in instrumenting the Soldier and suggest an approach to collecting this sort of data. |
