Use the Blank Message and Bus Assignment blocks to specify the x and y values of a 'geometry_msgs/Point' message type. Open the Blank Message block mask to specify the message type. set Sample time to 0.01. Open the Bus Assignment block mask to select the signals you want to assign. ...
Click on Select next to the Message type box, and select geometry_msgs/Point from the resulting pop-up window. set Sample time to 0.01. Click OK to close the block mask. From the Simulink > Signal Routing tab in the Library Browser, drag a Bus Assignment block. Connect the output port...
