Scientists build first 'liquibots' that run continuously without electricity
Inspired by water-walking insects, scientists have built liquid robots that work autonomously and continuously without the need for electrical inputs, transporting chemicals back and forth while partially submerged in solution. The "liquibot" technology may lead to further developments in automated chemical synthesis or drug delivery systems for pharmaceuticals, say the researchers, including those from Lawrence Berkeley National Laboratory in the US.
