There are many politicians who have an innate tendency to move in the direction of any flash light or camera. Tenagers in the age of the “not-so-social media” have a similar reflex. More seriously, Science Advances, has presented a fully autonomous robot with such a behavior. In fact this form of light locomotion is named the “twirlbot”. It has been developed by Chi Chen et al. (2026) as a new kind of robot that can be directed using light impulses, as only energy source for moving towards the light source. The from of locomotion is inspired by nature (bionics) and more precisely the “tumbleweed” way of moving, better rolling forward, driven by wind energy. The tumbleweed-inspired rolling robot, short “twirlbot”, does not need mechanical devices, just energy in a specific frequency range of light, which provides the heat for the photoactive, otherwise passive, bilayer strips. The polyhedral geometry of the twirlbot allows omni-directional locomotion. It really resembles the light active politician or any posing in the spotlight while doing the “loco-motion” (Video Link performance by “Little Eva” in the early 60s or a late 80s version by Kylie Minogue).
