An Evaluation and Development Environment for an ARM7-Based Autopilot Using the Atmel SAM7S256 Microcontroller Aug-2009 18 pages
Authors:  Justin L Shumaker; Ainsmar X Brown; ARMY RESEARCH LAB ABERDEEN PROVING GROUND MD VEHICLE TECHNOLOGY DIRECTORATE
The full text of this report is available for sale.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.


A Gimbaled Platform for Micro Aerial Vehicle Autopilot Simulation and Calibration Mar-2009 24 pages
Authors:  Justin L Shumaker; Kamal S Ali; Lamarious Carter; ARMY RESEARCH LAB ABERDEEN PROVING GROUND MD VEHICLE TECHNOLOGY DIRECTORATE
The full text of this report is available for sale.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 ...


Interfacing the TCM8230MD CMOS Camera with an ARM7 Microcontroller Mar-2009 20 pages
Authors:  Justin L Shumaker; ARMY RESEARCH LAB ABERDEEN PROVING GROUND MD VEHICLE TECHNOLOGY DIRECTORATE
The full text of this report is available for sale.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 ...
