ChemBots are “soft, flexible, mobile objects that can identify and maneuver
through openings smaller than their static structural dimensions”
Soft and squishy chemical robots will one day squeeze through tight spots then expand to 10 times larger, offering an advantage over rigid robots. Once a mission is complete, a chembot would biodegrade.
The chembots could get into a building through a crack, for example. They could explore a cave or crevice and dismantle an explosive. Or they might climb ropes, wires or trees. Another tiny idea: One chembot could pack a smaller chembot into a situation, then release it for even more minute explorations.
