Inverse kinematics solution for trajectory tracking using artificial neural networks for SCORBOT ER-4u
This paper presents the kinematic analysis of the SCORBOT-ER 4u robot arm using a Multi-Layered Feed-Forward (MLFF) Neural Network. The SCORBOT-ER 4u is a 5-DOF vertical articulated educational robot with revolute joints. The Denavit-Hartenberg and Geometrical methods are the forward kinematic algorithms used to generate data and train the neural network. The learning of forward-inverse mapping enables the inverse kinematic solution to be found. The algorithm is tested on hardware (SCORBOT-ER 4u) and reliable results are obtained. The modeling and simulations are done using MATLAB 8.0 software
Dise帽o e implementaci贸n de control a trav茅s de matrices de cinem谩tica para el brazo rob贸tico SCORBOT ER 4U ubicado en el Instituto Tecnol贸gico de Costa Rica
Proyecto de graduaci贸n (Licenciatura en Ingenier铆a en electr贸nica) Instituto Tecnol贸gico de Costa Rica. Escuela de Ingenier铆a en Electr贸nica, 2019.This document aims to describe the technological update carried out at the
Technological Institute of Costa Rica at the San Carlos regional headquarters to
a SCORBOT ER-4U handling robot between the second semester of 2019 and
the first semester of 2019.
The implementation of a master-slave structure between Python and Processing
was carried out for the communication of the control with the interface
created and developed in a Raspberry Pi 3 B+, as well as logical tests of the
sensors and encoders and mechanics for the mechanical restoration as the location
in the zero position and a control system was developed using kinematic
matrices given by Denavit-Hartenberg.
The control obtained must be improved and the implementation of another
controller is recommended as well as improving the power system by replacing
the power source with specific circuits for the implemented systems
