The task of each node(let) in sensor_filters is very simple: load the filter chain, subscribe ~input topic, and publish the filtered messages to ~output topic. If we receive a setPose message to reset the filter, we can get in strange situations wherein we process the pose reset, but then even after another spin cycle or two, we can get a new message with a time stamp that is older than the setPose message's time stamp.

In general, message_filters nodes are about filtering or coordinating message deliver, no matter the content of the messages, while image_transport nodes are concerned with manipulating the content of the messages. If a program is linked with geometric_shapes and robot_self_filter, it may cause strange behavior because of symbol Definition at line 494 of file ros_filter. g. Here is the origin code. So far, I have succeeded in sending my IMU readings to ROS from an Arduino (at a rate of around 100Hz, publishing Accelerometer, Gyro and Magnetometer to ROS). It is written in modern C++ and more type-safe than the original version. Then, I created a node that takes that data and builds two messages This class acts as a highest-level filter, simply passing messages from a ROS subscription through to the filters which have connected to it.
