   Sammanfattning : The Internet of Things (IoT) is widely adopted across various fields due to its flexibility and low cost. Energy-harvesting Wireless Sensor Networks (WSNs) are becoming a building block of many IoT applications and provide a perpetual source of energy to power energy-constrained IoT devices. LÄS MER

4. 23. Measurement of mechanical vibrations : Measurement of ambient energy in the form of mechanical vibrations in transportation, storage and installment for the use of self-powered wireless sensor networks

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Oskar Nordström; [2023]
   Nyckelord :;

   Sammanfattning : This project aims to explore the feasibility of using energy harvesting to create a self-powered sensor node that doesn't require batteries. The project was initiated by Ericsson, who identified a need to monitor their radio products during delivery to ensure they are not damaged by vibrations that exceed design specifications. LÄS MER

7. 25. Hanging Load Mock-Up For Experimental Setup To Test Flight System Stability

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

   Författare :Anthony Gundstedt; [2023]
   Nyckelord :drone; hanging; variable length; mixer matrix; PID; controller; microcontroller; RC; Telnet; I2C; FrSKY; Sbus; S.bus; Forestry; AirForestry; Swing; anti-swing; IMU; filter;

   Sammanfattning : Can we reduce disturbance, swing, and errors by delegating some of the tasks to a subsystem on the tool hanging from a drone to gain precision and dependability? This project covers developing and implementing a user-controlled prototype with an automatic control system and gripper for functionality and controlled movement in 5 DOF. AirForestry is developing a new way of working in the forestry business to provide a greener and healthier solution for the soil and the environment. LÄS MER
