In the past few years, we have covered plenty of clever robots here. This light powered fairly-like robot is also worth a look. Researchers of the Light Robots group at Tampere University Hao Zeng & Jianfeng Yang are behind this design.
As they explain, this robot can be powered by light sources such as a laser beam. A light beam can be used to control take-off/landing. The fairy robot can adapt to wind direction by changing its shape. Such robots can be used for artificial pollination.
