TC : This vacuum-activated modular robot is equally nasty and neat

Soft robots are a major area of research right now, but the general paradigm seems to be that you pump something (a muscle or tube) full of something else (air, fluid) causing it to change its shape. But a robot from Swiss roboticists does the opposite: its little muscles tense when the air in them is removed. It’s cool — but it also looks kind of gross.
