rosoutのトピックを見る

Last updated at Posted at 2021-11-14

rosプログラム内でデバッグ用のloginfoなどを使用するとrosoutというメッセージが出力されます。今回はこのトピックがどんな感じか見てみます。

まず,roscoreと以下URLのプログラムを実行します。

そして,rostopic echo /rosoutを実行します。

結果は以下のように,メッセージやそのログレベル,実行ファイル名などが表示されます。

因みにrosoutのメッセージ型はrosgraph_msgs/Logというものみたいです。

$ rostopic type /rosout
rosgraph_msgs/Log
