Mastering ROS for Robotics Programming

By: Lentin Joseph

Overview of this book

The area of robotics is gaining huge momentum among corporate people, researchers, hobbyists, and students. The major challenge in robotics is its controlling software. The Robot Operating System (ROS) is a modular software platform to develop generic robotic applications. This book discusses the advanced concepts in robotics and how to program using ROS. It starts with deep overview of the ROS framework, which will give you a clear idea of how ROS really works. During the course of the book, you will learn how to build models of complex robots, and simulate and interface the robot using the ROS MoveIt motion planning library and ROS navigation stacks. After discussing robot manipulation and navigation in robots, you will get to grips with the interfacing I/O boards, sensors, and actuators of ROS. One of the essential ingredients of robots are vision sensors, and an entire chapter is dedicated to the vision sensor, its interfacing in ROS, and its programming. You will discuss the hardware interfacing and simulation of complex robot to ROS and ROS Industrial (Package used for interfacing industrial robots). Finally, you will get to know the best practices to follow when programming using ROS.

Understanding the Moveit! configuration of a universal robotic arm


The changes that we need to make in the industrial MoveIt! configuration are almost the same as the arm we already worked with.

First, we have to define the controller.yaml file, which has to create inside ur10_moveit_config/config. Here is the definition of the controller.yaml of UR-10:

controller_list:
  - name: ""
    action_ns: follow_joint_trajectory
    type: FollowJointTrajectory
    joints:
      - shoulder_pan_joint
      - shoulder_lift_joint
      - elbow_joint
      - wrist_1_joint
      - wrist_2_joint
      - wrist_3_joint

The kinematics.yaml file inside the config folder contains the IK solvers used for this arm; we can use the following IK solvers. The contents of this file are given as follows:

#manipulator:
#  kinematics_solver: ur_kinematics/UR10KinematicsPlugin
#  kinematics_solver_search_resolution: 0.005
#  kinematics_solver_timeout: 0.005
#  kinematics_solver_attempts: 3
manipulator:
  kinematics_solver...
