By using fluids similar to Silly Putty that can behave as both liquids and solids, researchers say they have created fluid robots that might one day perform tasks that conventional machines cannot.​

They control the robot's shape and motion using audio waves, saying these robots could be ideal for "unfamiliar, hostile, or chaotic environments" because the robots are "free of constraints such as skin or obligatory structural integrity". The original article is in Artificial Life, Vol. 22, No. 1 (MIT Press).

Now I feel bad for being human and suffering from obligatory structural integrity!
