Gerardo Carmona / Mbed 2 deprecated AVC_Robot_Controled_Navigation

Not finished. This is my first attemp to make an autonomous vehicle for the Sparkfun Autonomous Competition (https://avc.sparkfun.com/) of June 2015.

Dependencies:   FXOS8700CQ SDFileSystem mbed

Fork of AVC_Robot_Controled_Navigation by AVR Competition

  • For my autonomous robot I will use a GPS, magnometer, accelerometer, and encoders.
  • I control my robot with a remote control to save the GPS points (detect turns) using a xBee radio and save them to a file in a SD card.
