  1. 1. Comparative Analysis of the Inverse Kinematics of a 6-DOF Manipulator : A Comparative Study of Inverse Kinematics for the 6-DOF Saab Seaeye eM1-7 Manipulator with Non-Conventional Wrist Configuration

    University essay from Linköpings universitet/Reglerteknik

    Author : Anton Larsson; Oskar Grönlund; [2023]
    Keywords : ;

    Abstract : This report presents various methods for solving the inverse kinematic problem for a non-conventional robotic manipulator with 6 degrees of freedom and discusses their respective advantages and disadvantages. Numerical methods, such as gradient descent, Gauss-Newton and Levenberg-Marquardt as well as heuristic methods such as Cyclic Coordinate Descent and Forward and Backward Reaching Inverse Kinematics are discussed and presented, while the numerical methods are implemented and tested in simulation.

  3. 2. Precision Tailoring Cooling Systems using Linear Regression

    University essay from KTH/Matematisk statistik

    Author : Kajsa Bjelle; Ida Cui; [2021]
    Keywords : Regression analysis; nonlinear regression; linear regression; Levenberg-Marquardt; applied mathematics; friction factor; wavy fin; bachelor thesis; Regressionsanalys; ickelinjär regression; linjär regression; Levenberg-Marquardt; tillämpad matematik; friktionsfaktor; wavy fin; kandidatexamensarbete;

    Abstract : This bachelor thesis is written for KTH Royal Institute of Technology and Ymer Technology AB. It examines the friction factor associated with the pressure drop in wavy-fin heat exchangers. Previous studies have used a nonlinear approach for determining the regression coefficients. READ MORE

  4. 3. Physically Inspired Optimization

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Abstract : Optimization is the study of finding the best solution for a problem. The applications of this field ranges from finding the best routes for travelling to finding the ground state of physical systems. READ MORE

  5. 4. A comparison between a traditional PID controller and an Artificial Neural Network controller in manipulating a robotic arm

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

    Author : Joseph Ariss; Salim Rabat; [2019]
    Keywords : Artificial Intelligence; Artificial Neural Network; Control System; PID Controller; Model Reference Controller; Robot arm; Artificiell Intelligens; Artificiell Neuralt Nätverk; Kontroll System; PID-kontroller; Modellreferenskontroller; Robotarm;

    Abstract : Robotic and control industry implements different control technique to control the movement and the position of a robotic arm. PID controllers are the most used controllers in the robotics and control industry because of its simplicity and easy implementation. However, PIDs’ performance suffers under noisy environments.

  6. 5. A polynomial phase model for estimation of underwater acoustic channels using superimposed pilots

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Felix Trulsson; [2019]
    Keywords : ;

    Abstract : In underwater acoustic communications the time variation in the channel is a huge chal- lenge. The estimation of the impulse response at the receiver is crucial for the decoding of the signal to become accurate. READ MORE
