Motor Controller Board For Cubesat Reaction Wheels, Tanner Ehlers
Motor Controller Board For Cubesat Reaction Wheels, Tanner Ehlers
Electrical Engineering
Reaction wheels are crucial for CubeSats, providing precise attitude control and stability in the environment of space, enabling successful mission execution. The ‘Reaction Wheels’ project in the Cal Poly CubeSat Lab is in need of a new motor controller board due to the current board’s malfunction and inefficiencies in terms of size, complexity, power usage, and cost. Previously, other students have completed work on the mechanical design of the system, but little work has been done for the electrical components. The goal of this project is to design and test a new motor controller board that is compact, lightweight, power …
Motor Control Quantification And Necessary Improvements For Individuals With Post-Stroke Gait: Implications For Future Customizable Rehabilitation Approaches, Azarang Asadi
Doctoral Dissertations
Although often taken for granted, walking is an extremely complex motor skill that requires sensory inputs, neural communication, advanced control strategies, and coordination of the muscles and joints. Electrical signals traveling from the brain to the muscles are transformed to mechanical forces to achieve desired motion. A stroke damages the central nervous system and neural pathways, limiting the ability of survivors to walk. Walking speed is significantly decreased and asymmetrical walking patterns emerge. A crucial component of stroke rehabilitation is gait training, a therapeutic intervention to help individuals to improve their walking ability, as walking is essential for functional independence …
