Tutorials
A comprehensive set of tutorials are now available for the ARan robot in Robots/ARan-base/Tutorials. The tutorials make use of the Gazebo simulator and currently contain tutorials on autonomous navigation. Comprehensive instructions on how to install the public simulator are provided.
Public simulation packages overview
This section presents an overview of the packages used in the public simulation of ARan, with links to the corresponding wiki pages describing the packages. For the installation instructions of the packages please refer to ARan simulation installation tutorial.
Control the robot
ARan supports a logitech joystick by default.
Controllers from other vendors may have different key mappings. In this case the joy_teleop.yaml file needs to be changed to reflect the different configuration.
If you had one plugged in when you started up the (real or simulated) robot, now it can be used. Activate the joystick commands by pressing the 'X' button, and drive using the controllers. This activation behaviour comes in very handy when the robot is navigating autonomously but a rapid interruption is needed.
One can also use the rqt_robot_steering plugin to drive the robot by sending commands directly to /mobile_base_controller/cmd_vel
