Liquid Metal Logic for Soft Robotics

چکیده
While there are many soft matter sensing and actuation technologies, is far less choice when it comes to material devices for control computation. One solution the Soft Matter Computer (SMC) which can perform both analogue digital computations in materials. This computer processes a fluidic input pattern consisting of alternating regions conducting insulating fluids into an electronic output signal. However, use salt water as conductive fluid means that has high electrical resistance requires AC voltage, making untethered operation impractical. In this letter, we introduce liquid metal (LM-SMC), uses galinstan alternative fluid. We show by switching metal-sodium hydroxide input, reduce SMC three orders magnitude, allowing at DC voltages 2 Volts under. characterise stability patterns demonstrate potential LM-SMC using bipolar ionic polymer composite shape memory alloy actuators. By enabling fully computation multiple actuators from single low voltage source, enables new class intelligent machines.

Soft robotics for chemists.
In areas from assembly of machines to surgery, and from deactivation of improvised explosive devices (IEDs) to unmanned flight, robotics is an important and rapidly growing field of science and technology. It is currently dominated by robots having hard body plans—constructions largely of metal structural elements and conventional joints—and actuated by electrical motors, or pneumatic or hydrau...
متن کاملDielectric Elastomer Based "Grippers" for Soft Robotics.
The use of few stiff fibers to control the deformation of dielectric elastomer actuators, in particular to break the symmetry of equi-biaxial lateral strain in the absence of prestretch, is demonstrated. Actuators with patterned fibers are shown to evolve into unique shapes upon electrical actuation, enabling novel designs of gripping actuators for soft robotics.

متن کاملFuzzy Logic for Culture-aware Robotics
In the context of culture-aware robotics, we propose a method for the explicit, on-line mapping between cultural variables and robot behaviour parameters which relies on the linguistic variable formalism, fuzzy clustering and the principles of fuzzy controllers. As a case study, we consider the adaptation of the Human-Robot conversational distance to Hofstede’s cultural dimension of Individualism.
