Getting Started with Turtlesim

Start the roscore:

$ roscore

To install and start the turtlesim:

$ sudo apt-get install ros-$(rosversion -d)-turtlesim

Run turtlesim:

$ rosrun turtlesim turtlesim_node

You'll see the turtlesim window:

Nodes

New in ROS hydro As of Hydro turtlesim uses the geometry_msgs/Twist message instead of its own custom one (turtlesim/Velocity in Groovy and older). Also the topic has been changed to cmd_vel (instead of command_velocity before).

turtlesim_node

turtlesim_node provides a simple simulator for teaching ROS concepts.

Subscribed Topics

turtleX/cmd_vel (geometry_msgs/Twist)

Published Topics

turtleX/pose (turtlesim/Pose)

Services

clear (std_srvs/Empty) reset (std_srvs/Empty) kill (turtlesim/Kill) spawn (turtlesim/Spawn) turtleX/set_pen (turtlesim/SetPen) turtleX/teleport_absolute (turtlesim/TeleportAbsolute) turtleX/teleport_relative (turtlesim/TeleportRelative)

Parameters

~background_b (int, default: 255) ~background_g (int, default: 86) ~background_r (int, default: 69)

mimic

mimic provides a simple interface for making one turtlesim mimic another.
