我们的3D打印统一软机器人包括完全集成的流体电路，能够进行复杂的操作。软机器人的出现给控制这类系统的底层流体提出了新的挑战。在这里，我们介绍了一种通过PolyJet三维(3D)打印在一次打印运行中添加制造统一软机器人的策略，该机器人包括完全集成的流体电路。我们探索了这种方法对于软机器人的有效性，该方法旨在利用新型3D流体电路元件--例如，流体二极管、“常闭”晶体管和具有几何可调压力-增益功能的“常开”晶体管--响应于常规电子信号的流体模拟而操作，包括恒流[“直流(DC)”、“交流(AC)”启发和预编程的非周期性(“可变电流”)输入条件。通过使完全集成的软机器人实体(由软执行器、流体电路和身体特征组成)能够在一次运行中被快速传播、按需修改和3D打印，所提出的设计和附加制造策略为催化新类别的软机器人提供了独特的前景。
We 3D-print unified soft robots comprising fully integrated fluidic circuitry capable of sophisticated operations. The emergence of soft robots has presented new challenges associated with controlling the underlying fluidics of such systems. Here, we introduce a strategy for additively manufacturing unified soft robots comprising fully integrated fluidic circuitry in a single print run via PolyJet three-dimensional (3D) printing. We explore the efficacy of this approach for soft robots designed to leverage novel 3D fluidic circuit elements—e.g., fluidic diodes, “normally closed” transistors, and “normally open” transistors with geometrically tunable pressure-gain functionalities—to operate in response to fluidic analogs of conventional electronic signals, including constant-flow [“direct current (DC)”], “alternating current (AC)”–inspired, and preprogrammed aperiodic (“variable current”) input conditions. By enabling fully integrated soft robotic entities (composed of soft actuators, fluidic circuitry, and body features) to be rapidly disseminated, modified on demand, and 3D-printed in a single run, the presented design and additive manufacturing strategy offers unique promise to catalyze new classes of soft robots.
