  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

    Master-uppsats, Linköpings universitet/Reglerteknik

    Författare :Anton Larsson; Oskar Grönlund; [2023]
    Nyckelord :;

    Sammanfattning : 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.

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

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Joseph Ariss; Salim Rabat; [2019]
    Nyckelord :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;

    Sammanfattning : 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.

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

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Felix Trulsson; [2019]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER
