This 22cm, 1.5gram gliding robot can autonomously detect and fly towards a light source. Its tail is acutated using a novel 0.2gram Shape Memory Alloy (muscle wire) acutator. For more inforamation about its context and other bioinspired jumping and flying robots, please visit lis.epfl.ch

"Phototaxis behavior is commonly observed in animals with light-sensing organs. C. elegans, however, is generally believed to lack phototaxis, as this animal lives in darkness (soil) and does not possess eyes. Here, we found that light stimuli elicited negative phototaxis in C. elegans and that this behavior is important for survival. Tail avoidance response. At 1.72 s, a flash of light (2 s duration, UV-A) was turned on. At 2.85 s, the worm responded by stopping backward movement and ...

, sporadic and above all interesting to me. Though it is quite apparent, it is still a mystery to lepidopterists (moth and butterfly scientists) as to why moths are so attracted to light. Phototaxis is an organism's automatic movement toward or away from light. Moths are positively phototactic meaning they naturally feel the need to move toward a light source rather than away. Dependency on entities outside of oneself (though it shows trust to some degree) is unstable and weak. The concept of ...
