With a wingspan of 63 cm and weighing in at 175 grams, the robotic dragonfly mimics all forms of flight as its natural counterpart, including hover, glide and manoeuvring in all directions. This is made possible, the company says, by the BionicOpter’s ability to move each of its four wings independently, as well as control their amplitude, frequency and angle of attack. Including its actuated head and body, the robot exhibits 13 degrees of freedom, which allows it to rapidly accelerate, decelerate, turn and fly backwards." Link to Original Source
A method of solution is perfect if we can forsee from the start,
and even prove, that following that method we shall attain our aim.
