I computed: and i got ca. 70 Hz. What is the meaning of the number 99.2 Hz? |

2018-11-13 14:03:46 -0500 | marked best answer | Logging and processing the same sensor data Hi all, In my system I have a sensor that sends data via TCP/IP. This data should be logged for future processing and also used for a live computation at the same time. Since i am a newbie to ROS, I have a question concerning a good design for the situation above. Does it make sense to write a node(let) which simply opens the socket, reads the data and publishes the bytes as they come from the sensor. Then use two node(let)s to subscribe to the topic? Or better, one node reads the data, processes it and writes the data to a rosbag? What happens to this design if there are 20 sensors? Regards |

2018-11-10 03:27:23 -0500 | commented answer | Logging and processing the same sensor data @PeteBlackerThe3rd, i agree with you. The idea is always to have the sensor data in an abstract layer. |
