Self-balancing scooter : How to construct a Self-balancing scooterRosencrantz, Frans January 2016 (has links)
This rapport deals with the construction of a self-balancing scooter. A self-balancing scooter is a two-wheel vehicle where the velocity is controlled by the tilt of the driver. When the driver leans forward and backward, the vehicle is running forward and backwards. The main task was to determine if the Arduino microcontroller could be used for the control system. An iron frame, control circuit and a tilt able handlebar were constructed. Two recycled permobil DC-motor were mounted onto the iron frame. An accelerometer and a gyrometer were obtaining the tilt of the handlebar and the scooter. The system was using locked Anti-phase drive and a PI-regulator to control the motors. The self-balancing scooter prototype worked well and was able to balance without any external help. The driver was able to control the speed by tilting forward or backward and was able to choose the direction by the tilt of the handlebar. The balance was affected negative by the backlashes from the gear and too weak H-bridges. If the project were made again, two three-phase hub motors with higher ratings would replace the DC-motors. Gears could be excluded and the backlashes are removed.

Human Mo-cap System Based on Inertial Measurement Units / Human Mo-cap System Based on Inertial Measurement UnitsGrzybowská, Martina January 2021 (has links)
Cieľom tejto práce je navrhnúť, zhotoviť a implementovať vlastný systém pre zachytávanie pohybu založený na inerciálnych meracích jednotkách. V rámci budovania teoretického základu bolo preskúmaných viacero metód, avšak primárne bola pozornosť venovaná samotnému inerciálnemu snímanu - jeho kladom a nedostatkom, kľúčovým vlastnostiam a jednotlivým komponentom potrebným pre zostrojenie systému na jeho báze. Tento úvodný zber informácií je nasledovaný fázami návrhu, zhotovenia a zhodnotenia, ktoré sa zaoberajú procesom vývoja a testovania daného riešenia. Hlavným prínosom realizácie systému je zostrojenie zariadení pre snímanie pohybu - jedná sa o malé, ľahké, batériovo napájané zariadenia, ktoré sú kompletne bezdrôtové, či už z hľadiska komunikácie s okolitým svetom, alebo vďaka napájaniu kompatibilnému so štandardom Qi.
