Micro Glider Project (2004-2005)


We proposed to develop a new class of very low mass (1 gram and below) and low-cost autonomous fliers which can cover a wide area, using gliding or active flight. Using insect-inspired optical-flow motion detection, large numbers of fliers will rapidly fan out to scout an area. An example application is in fighting forest fires, where large areas need to be inexpensively monitored. The piezo actuated control surfaces developed in the micromechanical flying insect project provide the breakthrough technology needed to construct such lightweight flying platforms.
This was a joint project between UC Berkeley and Centeye, Inc. The project results are described in R.J. Wood et al, IEEE Robotics and Automation Magazine, vol. 14, no. 2, June 2007.
