Micro Air Vehicle (MAV) is a lightweight flying object of around 300mm size that can be flown by a ground pilot through radio commands or through an autopilot built on an embedded system. Appropriate morphing or shape changing of MAV wing during flight has the potential to give different aerodynamic benefits, similar to birds but the implementation of such a system poses weight, power, response time and size challenges. The all-up weight of MAV should be around 300g and the flight is powered by a on-board battery which has very less power to spare, given the difficulty to meet the target endurance of about 30 minutes. Active morphing was achieved by drooping the Leading Edge (LE) of MAV wing. Such a morphing form has the potential to give higher lift during takeoff, low speed loitering, negotiation of high-rise structures and landing. A MAV designed and developed at NAL, namely 'Black Kite' was used for this purpose. This paper presents the Open source embedded controller namely Arduino adapted for the morphing of MAV using multiple Shape Memory Alloy based actuators. It describes a form of wing morphing obtained by drooping the leading edge, design and development of SMA based actuators, measurement and control of degree of morphing, integration of the whole system using the arduino autopilot board and the flight testing.
