Researchers are constantly working on solutions to enable robots to feel their surroundings like humans. A team at the Technical University of Munich has developed robot skin cells that can measure proximity, pressure, temperature, and acceleration. Computing power is used only when individual cells are activated.
This robotic skin learns to ignore constant signals just like humans. The H1 robot with this synthetic skin can accurate sense humans, walk on one leg, and hug humans safely. The above video shows what makes this robot skin special.
