Study of communication between driver sbRIO9632 and Raspberry Pi 3

The purpose of this article is to analyse communication between Raspberry Pi 3 and a mobile robot Starter Kit 2.0 equipped with sbRIO9632 driver. Sending data between devices was carried out by the TCP / IP protocol. The first chapter discusses the issues related to the duration of algorithms that recognize objects in images. Subsequently, the measurement system is presented along with the description of the TCP / IP protocol. Next, the method of testing the connection between Raspberry Pi 3 and the mobile robot was determined. The TCP / IP protocol was chosen as a way of data exchange and the server and communication client were established. Two time measurements were used to diagnose the TCP / IP connection. The first timer was measured from the time the image was taken from the camera by digital image processing, sending data to the server response. The second timer measured the communication time (sending the packet - response). Time measurements were made in two situations: communication was via a network cable and using a router (wireless communication). The last chapter of this article was the analysis of results and conclusions.
