Wireless communication can be defined as data transfer between two or more points that don’t have a conductive material in between. Wireless communication tools are important for robots. Wireless communication is especially important for mobile robots because they change position frequently and using them tethered is not possible. In wireless communication category, Wi-Fi modules, xBee modules, Bluetooth modules, RF modules and GPS modules are listed.
Most common wireless communication technologies use radio frequency. Radio waves can travel great distances. For that reason RF signals are commonly used in robotics. Wi-Fi modules that provide wireless communication for robotics and electronics projects started gaining high interest with the introduction of open source electronics development platform Arduino and internet of things (IoT) concept.
