ROS 6Dof robotic arm

Import stl into blender, scale to 0.001, rotate 90 degrees on the x axis, center on green line using the 3d cursor as origin, and export as collada for ROS.

Create a differential drive robot URDF with xacro in ROS, importing Blender models, defining base links and joints, and simulating in Gazebo with ros control and robot state publishers.

Explain how to structure a ros urdf xacro file for a 6dof robotic arm, detailing world and base links, joints, transmissions, inertial properties, and ros control integration.

Explore the ros launch file for the 6dof robotic arm, detailing urdf loading, joint state publisher launch, and spawning the model in gazebo using an empty world.

Demonstrates loading robot description and joint state and trajectory controllers from YAML via a ROS launch file, and explains publishing joint states and executing joint space trajectories.

Explain the ros service implementation in a robot controller package, focusing on the angles converter node, two services, and request-response flows for radian-degree conversions.

Explains the robot interface node in the ROS control framework, detailing hardware interface with joint state and command interfaces, and how the controller manager loads and communicates with Arduino hardware.

Explain the ros launch file, controller manager, and robot state publisher for 6dof arm control, and show arduino serial.py handling arduino arm commands via publishers and subscribers.

Set up a 6dof robotic arm with the Moveit framework by configuring URDF, planning groups, a CDDL kinematics solver, and defining poses like home and gripper open/close.

Explain the ros arduino integration for the arduino mega, including installing the serial library and using stepper and servo motors with ros node subscription.

Wire Arduino and motor drivers by connecting scl and sda, sharing five volt and ground, and wiring step and direction pins for each motor, with debugging pins 16 and 17.

Launch a complete MoveIt-based control of a real 6dof robotic arm by loading an Excel file and starting the MoveIt move group, controller, and RViz.
