  • There are some hardwaredecices on banggod.com or have a look to the Arduino, & 'community - for exaple: http://www.instructables.com/id/Wirelessly-Control-A-Robot-Using-Arduino-and-RF-Mo/?lang=de
    I know that the arduino is not the pic - but have similar ideas and approches... and a lot of practical tutorials....... have a nice day , Oliver

  • I am working on a stepper motor driven robot car, Already I can control the directional movement (Forward/backward/left/right) by wired medium. Now I want to make it wireless by RF. Is there any website for learning about RF transmitter and receiver?
