Sensorized Soft Actuator Datasets
No full textCalibration and evaluation dataset that was used by Scharff, 2019. With permission of the authors, this data has been made available with this article. The calibration dataset consists of the RGBC (red, green, blue, clear) measurements of the four color sensors and the corresponding 2D marker coordinates for 1000 different actuator configurations. The evaluation dataset consists of a video where the actuator interacts with a variety of objects in combination with the corresponding RGBC-measurements
3D-printed biomimetic artificial muscles using soft actuators that contract and elongate
No full textBiomimetic machines able to integrate with natural and social environments will find ubiquitous applications, from biodiversity conservation to elderly daily care. Although artificial actuators have reached the contraction performances of muscles, the versatility and grace of the movements realized by the complex arrangements of muscles remain largely unmatched. Here, we present a class of pneumatic artificial muscles, named GeometRy-based Actuators that Contract and Elongate (GRACE). The GRACEs consist of a single-material pleated membrane and do not need any strain-limiting elements. They can contract and extend by design, as described by a mathematical model, and can be realized at different dimensional scales and with different materials and mechanical performances, enabling a wide range of lifelike movements. The GRACEs can be fabricated through low-cost additive manufacturing and even built directly within functional devices, such as a pneumatic artificial hand that is fully three-dimensionally printed in one step. This makes the prototyping and fabrication of pneumatic artificial muscle-based devices faster and more straightforward.</p
A Soft Continuum Robotic Arm with a Climbing Plant‐Inspired Adaptive Behavior for Minimal Sensing, Actuation, and Control Effort
No full textA key challenge in designing soft continuum robotic arms is the realization of intelligent behavior while minimizing sensing, actuation, and control effort. This work investigates how soft continuum arms can benefit from mimicking the distribution of flexural rigidity of searcher stems in climbing plants to accomplish this goal. A modeling approach is presented to tune both the structural design and the tactile sensor design of a soft continuum arm inspired by the flexural rigidity distribution of Mandevilla cf. splendens’ searcher stems. The resulting soft continuum arm, named Mandy, can detect suitable supports along its length and twining around them using a single sensor and actuator. Through simulations and experiments, it is shown such behavior cannot be achieved with a soft continuum arm possessing uniform structural stiffness and a standard tactile sensor design. Thus, the significance of investing greater effort in structural design, leveraging biological data, to improve the design of soft continuum arms with more compact actuation and sensing hardware, is highlighted
Rob and Bert in Tokyo
No full textThis essay is steeped in contradiction: it is as much an attempt at mourning, coping, and letting go as it is an exercise in remembrance, rediscovery, and reconnection. One of the many areas of international legal scholarship where Rob Cryer left his mark is his oeuvre on the International Military Tribunal for the Far East (IMTFE). To pay tribute to, and get re-acquainted with, Rob-the-person, I re-read his 2010 article on the ‘dignified dissenter’ in Tokyo, Dutch Judge Bert Röling. In that article, Rob uses the memoranda and the opinion of Bert-the-judge to assess his conceptual and legal contributions to the IMTFE judgment. They also serve him as a vehicle to get a better grasp of the author behind the text and the values and dilemmas that shaped Röling’s positions on the IMTFE bench. What more can we learn and understand about Rob Cryer while ‘reading Rob reading Bert’? What aspects of Röling’s legacy did he choose to foreground, and what qualities did he appreciate most? How did Rob treat his character when shedding light on the more contentious elements of Röling’s work? Even if this essay fails in its therapeutic purpose, it might still add a few mosaic pieces to the collective construction of Rob’s portrait in this volume
Proprioception of GRACE artificial muscle utilizing macro-bending principle of fiber optics
No full textThe rapid growth of artificial intelligence (AI) and deep learning technologies has catalyzed transformative advancements across various domains, with Convolutional Neural Networks (CNNs) and Transformer models spearheading this evolution. Despite their potential, deploying these complex models on resource-constrained edge devices poses significant challenges, primarily due to inherent memory and computation bottlenecks. This thesis investigates innovative compute-in-memory (CIM) architectures aimed at addressing these challenges, with a particular focus on enhancing AI acceleration in edge environments. We present a suite of CIM designs, featuring SRAM-based CIM macros that utilize a time-current-based multiply-and-accumulate (MAC) mechanism, alongside a novel hybrid CIM architecture, which seamlessly combines SRAM and non-volatile Resistive RAM (ReRAM) technologies. These designs are crafted to minimize data transfer, boost energy efficiency, and preserve computation accuracy, all of which are essential for real-time AI applications on edge devices. The SRAM CIM design achieves high throughput and energy efficiency by embedding MAC and ADC operations directly within SRAM cells. In contrast, Hybrid CIM leverages the high density of ReRAM and the rapid processing capabilities of SRAM to enhance the computation speed, precision and resilience against device variations. Moreover, we propose a hybrid CIM accelerator architecture specifically optimized for the deployment of CNNs and Transformers on edge devices. This architecture integrates ReRAM and SRAM at a fine granular level and employs a differential sensing scheme to enable efficient and accurate parameter storage and retrieval. An algorithm-architecture co-design strategy is implemented to optimize the data flow of Multi-Head Attention (MHA) in the Transformer models, effectively alleviating I/O bottlenecks and improving scalability for processing long sequences. Experimental evaluations reveal that our design achieves remarkable energy efficiency and inference throughput, outperforming existing architectures and establishing itself as a promising solution for accelerating Al on edge devices.</p

Mechanochromic Suction Cups for Local Stress Detection in Soft Robotics
No full textAdvancements in smart soft materials are enhancing the capabilities of robotic manipulators in object interactions and complex tasks. Mechanochromic materials, acting as lightweight sensors, offer easily interpretable visual feedback for localized stress detection, structural health monitoring, and energy-efficient robotic skins. Herein, an innovative mechanochromic soft end-effector capable of discerning local contact stresses during mechanical interactions with objects is presented and their relative position is ascertained. This system utilizes a reversible force-induced color switch in a thin layer of spiropyran-functionalized polydimethylsiloxane, which coats a silicone-made suction cup. The mechanochromic suction cup is integrated with a 3D-printed compact load-transferring system and electronic color-changing detection elements. The assembly may serve as a synthetic receptor for robotic actuators, discerning localized interaction forces down to 3 N. The system's resilience to varying environmental factors, including illumination, tilting, and interaction with objects of various shapes is verified. The results indicate potential for exteroceptive solutions in reconfigurable manipulation tasks without compromising the overall softness of the manipulator
