Professor Ron Fearing and his students at the University of California at Berkeley are using Dickinson's information to build a micromechanical fly. In the photo a 30% larger than final size scale mockup of the Micromechanical Flying Insect (MFI) is compared with its inspiration, the blow fly Calliphora erythrocephala. Researchers expect the stainless steel MFI to be flying in the lab by 2003. The main problem to be overcome in such a small device is an adequate power supply.
