I´m starting a project to implement a simple Object Avoidance on AQ using this promising Laser system "LIDAR-Lite" (Light Detector and Ranging) https://www.sparkfun.com/products/13167
Other projects like APM have already implemented this system (http://copter.ardupilot.com/wiki/common ... e/?lang=es)
To simplify the implementation (for me), the first step will be to add an independent sysbystem in between the Rx and the AQ control board that will read the LIDAR signal and manipulate the Pitch/Roll signal before inyecting to FC board. The idea is replicate what your eyes/fingers do when flying in front of a wall.
This intermediate subsystem is based on an ARDUINO-UNO board, and a servo for tilting the LIDAR 180º as an scanner - RADAR way. The code will add-remove PWM values to the Pitch/Roll signal received from the Tx in base of what LIDAR "see" around it. If none obstacle in front, no signal modification.
A second step will be a full itegration inside AQ code using the I2C inteface available.
Comments and ideas are wellcome
