Blog by Laura Tripaldi :”…Over the past 20 years, robotics has undergone a significant transition. A field once dominated by anthropomorphic bodies and rigid materials has begun to embrace a much wider range of possible incarnations, starting with the use of plastic and flexible materials to replace steel and hard polymers. Cecilia Laschi, one of the most authoritative figures in the field of robotics, has frequently emphasized how this transition from “rigid” to “soft” robots goes far beyond a simple change in the choice of materials, reflecting instead a broader transition in the entire anatomy of the automata, in the strategies used to control them, and in the philosophy that drives their construction. The most notable engineering achievement by Laschi and her colleagues at the Sant’Anna Institute in Pisa is a robotic arm originally designed in 2011 and inspired by the muscular hydrostatics of the octopus. In octopuses, limbs are capable of complex behaviors such as swimming and manipulating objects through coordinated deformations of muscle tissue, without any need for rigid components. In the robot designed by Laschi and her colleagues, the robotic limb’s movement is achieved similarly through deformable smart materials known as “shape memory alloys.”
Unlike a conventional robot, these movements are not pre-programmed, but emerge from the material’s response to external forces. This new engineering logic is part of what Laschi describes as embodied intelligence, an approach in which the robot’s behavior emerges from integrating its physical structure and interaction with the world. The concept of “embodiment” challenges the hierarchical separation between body and mind, representation and experience. Rather than conceiving of intelligence as the product of an active mind controlling a passive body, embodiment emphasizes the relationship between cognition and corporeality. Originating in philosophy, over the last 20 years, this concept has begun to spread and establish itself in the field of engineering, opening up new avenues for the design of versatile and adaptive robots. “The octopus is a biological demonstration of how effective behavior in the real world is closely linked to body morphology,” Laschi and her co-workers explain, “a good example of embodied intelligence, whose principles derive from the observation in nature that adaptive behavior emerges from the complex and dynamic interaction between body morphology, sensorimotor control, and the environment.”…(More)”.
