Roboticists have begun to design biologically inspired robots with soft or partially soft bodies, which have the potential to be more robust and adaptable, and safer for human interaction, than traditional rigid robots. However, key challenges in the design and manufacture of soft robots include the complex fabrication processes and the interfacing of soft and rigid components. We used multimaterial three-dimensional (3D) printing to manufacture a combustion-powered robot whose body transitions from a rigid core to a soft exterior. This stiffness gradient, spanning three orders of magnitude in modulus, enables reliable interfacing between rigid driving components (controller, battery, etc.) and the primarily soft body, and also enhances performance. Powered by the combustion of butane and oxygen, this robot is able to perform untethered jumping.
机器人专家已经开始设计具有柔软或部分柔软身体的受生物启发的机器人，与传统的刚性机器人相比，这些机器人具有更强的健壮性和适应性，并且在人机交互方面更安全。然而，软机器人设计和制造中的关键挑战包括复杂的制造工艺以及软、硬部件的接口。我们使用多材料三维（3D）打印来制造一种燃烧动力机器人，其身体从刚性核心转变为柔软的外部。这种跨越三个模量数量级的刚度梯度，使刚性驱动组件（控制器、电池等）与主要的柔软身体之间能够可靠地连接，并且还提高了性能。这种机器人由丁烷和氧气的燃烧提供动力，能够进行无绳跳跃。
