Control robot using Java over 2.4GHz RF link

In this demo, I am showing it is possible to control an Arduino Robot from a host PC using Java. There are two Arduino Uno (compatible) boards used. Each equips with 2.4GHz RF module. The base station connects to a laptop PC. I coded a simple Java GUI (using Swing) with just 4 buttons. The program sends the ‘left’, ‘right’, ‘forward’, ‘backward’ commands to the robot through 2.4GHz radio frequency  (Nordic Semiconductor nRF24L01+) link.
