Introduction

GAZEBO

simulate 1+ robots in environments filled with static and dynamic objects, lighting, and programmable interactions.

gzserver = parsing the description files => simulates the complete scene

gzclient = connects to the gzserver & renders the simulation scene along with useful interactive tools.

$ gazebo

Unified Robot Description Format (URDF)= XML format

1. define a robot model,

2. kinodynamic properties,

3. visual elements / sensors

CAN: describe a robot with rigid links connected by joints in a chain or tree-like structure.

CANT: flexible links or parallel linkage.

1 URDF = N Xacro (XML Macros)

RViz = ROS Visualizer. (a ROS package)

RViz shows all 3 core aspects of a robot: Perception, Decision Making, and Actuation.
