Vodka-powered robots harness Cheerios-inspired physics for movement in bizarre experiment | Higher alcohol concentrations helped achieve even greater robot speeds
The bots were developed by a team led by Jackson Wilt at Harvard University. As reported by New Scientist, they experimented with 3D-printed plastic pucks around a...
Higher alcohol concentrations simply worked better as a fuel source for achieving greater propulsion, with Wilt noting that beer would not be as effective. Using multiple robots also helped demonstrate the "Cheerios effect" – the clustering of floating objects caused by attractive forces between the meniscuses they create on the water's surface. Wilt suggests they could potentially be used to evenly disperse substances through bodies of water for environmental remediation or certain industrial processes that require timed material distribution.
