“…Amphibians adapt to different environments, including on ground, in water, and through transitional zones. Motivated by this, amphibious robots 44 – 46 with high adaptivity have drawn great attention for broad applications, such as resource exploration, disaster rescue, and military reconnaissance. However, these amphibious robots usually need to combine different structures, actuation systems, or control strategies to realize locomotion both on the ground and in water.…”

Wireless millimeter-scale origami robots have recently been explored with great potential for biomedical applications. Existing millimeter-scale origami devices usually require separate geometrical components for locomotion and functions. Additionally, none of them can achieve both on-ground and in-water locomotion. Here we report a magnetically actuated amphibious origami millirobot that integrates capabilities of spinning-enabled multimodal locomotion, delivery of liquid medicine, and cargo transportation with wireless operation. This millirobot takes full advantage of the geometrical features and folding/unfolding capability of Kresling origami, a triangulated hollow cylinder, to fulfill multifunction: its geometrical features are exploited for generating omnidirectional locomotion in various working environments through rolling, flipping, and spinning-induced propulsion; the folding/unfolding is utilized as a pumping mechanism for controlled delivery of liquid medicine; furthermore, the spinning motion provides a sucking mechanism for targeted solid cargo transportation. We anticipate the amphibious origami millirobots can potentially serve as minimally invasive devices for biomedical diagnoses and treatments.

“…While some topics addressed in this text overlap with the prior survey, the focus of this paper is different: it concentrates on additional topics, such as biological sensing systems, biologically inspired or mimicked vision and tactile sensors, and datasets and neural network-inspired fusion algorithms. Biological systems are the inspiration sources of various robotic engineering studies [36]. This paper surveys the state of the art of VTFP in humanoids regarding their natural counterparts.…”

Humanoid robots are designed and expected to resemble humans in structure and behavior, showing increasing application potentials in various fields. Like their biological counterparts, their environmental perception ability is fundamental. In particular, the visual and tactile perception are the two main sensory modes that humanoids use to understand and interact with the environment. Vision-Tactile Fusion Perception (VTFP) has shown multiple possibilities for better sensing understanding in challenging conditions, causing new research interests and questions. The overlap between visual and tactile perception in humanoids is continually growing. This work has reviewed the current state of the art of VTFP. It starts with the physiological basis of biological vision and tactile systems as well as the VTFP mechanisms as inspirations for humanoid perception. Then, the bioinspired visual-tactile fusion systems for humanoids are reviewed as the emphasis. After the survey on the vision and tactile sensors of robots, seven currently publicly available VTFP datasets are introduced. They are the data sources for several studies on neural network-inspired fusion algorithms. Furthermore, the applications of VTFP on humanoids are summarized. Finally, the challenges and future work are discussed. This review aims to provide several references for further exploitation of VTFP and its applications on humanoids.

“…Recent technological advances in computational analysis led to a new precise evaluation of these systems, building models that mimicke these biological designs, especially in robotics. Indeed, numerous examples of robots mimicking organismal shapes and movements emerged in recent decades, including air [79,80], underwater [81,82], and ground robots [83]. Notorious biological translations are the robotics arm OCTARM, inspired by the octopus [84], the Elephant Trunk Manipulator [85], and the numerous demonstrators developed by Festo Bionic Learning Network (Bionic Swift, BioincWheelBot, BioincANTS).…”

Organismal Design and Biomimetics: A Problem of Scale

et al. 2021

Organisms and their features represent a complex system of solutions that can efficiently inspire the development of original and cutting-edge design applications: the related discipline is known as biomimetics. From the smallest to the largest, every species has developed and adapted different working principles based on their relative dimensional realm. In nature, size changes determine remarkable effects in organismal structures, functions, and evolutionary innovations. Similarly, size and scaling rules need to be considered in the biomimetic transfer of solutions to different dimensions, from nature to artefacts. The observation of principles that occur at very small scales, such as for nano- and microstructures, can often be seen and transferred to a macroscopic scale. However, this transfer is not always possible; numerous biological structures lose their functionality when applied to different scale dimensions. Hence, the evaluation of the effects and changes in scaling biological working principles to the final design dimension is crucial for the success of any biomimetic transfer process. This review intends to provide biologists and designers with an overview regarding scale-related principles in organismal design and their application to technical projects regarding mechanics, optics, electricity, and acoustics.
