Como rodar a simulação

Adicione essas linhas no seu .bashrc. Adicione o caminho correto para o dinf_world no export e rode um source ~/.bashrc.

source /opt/ros/humble/setup.bash

export IGN_GAZEBO_RESOURCE_PATH="$HOME/caminho/para/o/arquivo/simulacao-Turtlebot3/gazebo/dinf_world"

Na pasta /dinf_world rode o comando ign gazebo -v -r dinf_world.sdf, você deverá ver a seguinte tela:

Turtlebot no dinf

No início, o Lidar não estará visível. Para fazer com que o gazebo escute o tópico do Lidar, clique no botão laranja em "Visualize Lidar". Para movimentar o Turtlebot, utilize o teleop que está na mesma aba, à direita.
