Upgrading a quad-copter with a proximity sensor for autonomous flight

Chris got his hands on a Crazyflie nano quadcopter.  Oddly enough the quad already comes with open source firmware and hardware ideal for hacking ( imagine that! )  So that’s just what he did.  The Crazyflie runs a STM32 (arm cortex m3) processor and FreeRTOS.  He got the upgraded package with a magnetometer, and altimiter, and can add a GPS too.  All things that are great for autonomous flight but it still isn’t smart enough to not bash into the wall.

Adding a proximity sensor would at least help with immediate obstacle avoidance (and walls), So he found a proximity sensor and dove right in learning C again.  Check out the full write-up here.

    Small correction, the unit can be interfaced with a GPS but does nit yet include one.
