This might just be the soft robot that possesses the most human traits of all: sweating. This robotic finger breaks out in a sweat to prevent itself from overheating, similar to what our bodies do during hot days or when we exert ourselves physically.
Soft robots are already useful because they can resist damage and grasp slippery things, but sweating might one day let them work in warm environments or handle hot objects.

While we've already seen a metal "brobot" that can sweat while doing pushups, this one [was] the first types of soft robots to get the tech. Scientists think that the tech could keep robots and other machines cooler than their surroundings in hot conditions. They also believe that the sweat pores could absorb liquids for analysis or coat the robots with protective chemicals.
It still is not perfect though, as scientists are still thinking about how to make it more mobile. More details over at EnGadget.
