Cold spray technology using micron-sized particles to produce coatings is increasingly used for reparative tasks in various industries. In a cold setup, the gun usually connected robotic arm deposit on components with complex geometries. For these components, standoff distance process has be large enough easy maneuverability of around small radial feature. However, commonly found most studies, ...

Change of direction (CoD) ability is critical for the success athletes in many sports. The purpose this study was to perform a principal component analysis using 9 CoD tests order reveal possible subcomponents ability, which could aid practitioners test selection. Male and female kinesiology students (n = 76) performed all 30-m sprint quasi-randomized, counterbalanced order. Three components ma...

Tracking maneuvering targets presents a great challenge to airborne surveillance radar signal processing and sensor systems management systems. Smears caused by an uncompensated maneuver (either translational or rotational) affect target identification (ID) with distorted target images. An unexpected maneuver introduces large position estimation errors to a tracker and in the worst case loss of...

The Robot Systems Division of the National Institute of Standards and Technology (NIST) has recently been experimenting with a variety of applications for the NIST ROBOCRANE. The ROBOCRANE design utilizes the basic idea of the Stewart Platform parallel link manipulator. The unique feature of the NIST approach is to use cables as the parallel links and to use winches as the actuators. Depending ...

Skid-steered robots are commonly used in outdoor applications due to their mechanical simplicity, high maneuverability, and robustness. The maneuverability of these robots allows them, under ideal conditions (e.g., flat terrain and powerful actuators), to perform turning maneuvers ranging from point turns to straight line motion. However, sloped terrain, terrain with high friction, or actuator ...
