1. 21. Autonomous Vehicles With Obstacle Avoidance

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Andree Hultgren; Muhammed Memedi; [2019]
   Keywords : ;

   Abstract : Autonomous ground vehicles are becoming prevalent in this modern society due to economical and environmental benefits. This paper investigates trajectory tracking control for a two-wheel autonomous vehicle first, and then a decentralised control approach is implemented where each vehicle can maintain a formation with other vehicles.

3. 22. 3D obstacle avoidance for drones using a realistic sensor setup

   University essay from KTH/Robotik, perception och lärande, RPL

   Author : Thor Stefansson; [2018]
   Keywords : robotics; drones; unmanned aerial vehicle; obstacle avoidance; 3D; realistic sensor setup; depth camera; lidar; obstacle restriction method; ORM; indoors;

   Abstract : Obstacle avoidance is a well researched area, however most of the works only consider a 2D environment. Drones can move in three dimensions. It is therefore of interest to develop a system that ensures safe flight in these three dimensions. READ MORE

4. 23. Improving path planning of autonomous vacuum cleaners using obstacle classification

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Tomas Andersson; Noa Spele; [2018]
   Keywords : ;

   Abstract : To effectively plan their movement, robotic vacuum cleaners require information about their surrounding environment. This thesis presents a mapping algorithm which uses collision input from a moving robot to create a grid map of the environment. The algorithm also classifies each obstacle cell in the grid map as either mobile or immobile. READ MORE

5. 24. Investigation of phase conjugation for medical imaging

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

   Author : Ivan Sytcevich; [2017]
   Keywords : Phase conjugation; Ultrasound Optical Tomography; Rare-Earth-Doped Crystals.; Physics and Astronomy;

   Abstract : With the development of extremely precise spectral filters based on spectral hole burning and slow light effects, the idea of their implementation in an Ultrasound Optical Tomography (UOT) medical imaging technique arose. Simulations have shown that the resulting Contrast-to-Noise (CNR) ratio is fairly good at depths up to 5 cm but decreases dramatically when probing deeper in tissue. READ MORE

6. 25. Navigability Assessment for Autonomous Systems Using Deep Neural Networks

   University essay from Linköpings universitet/Datorseende

   Author : Ebba Wimby Schmidt; [2017]
   Keywords : autonomous systems; autonomous robots; deep learning; convolutional neural networks;

   Abstract : Automated navigability assessment based on image sensor data is an important concern in the design of autonomous robotic systems. The problem consists in finding a mapping from input data to the navigability status of different areas of the surrounding world. Machine learning techniques are often applied to this problem.
