In industrial applications Finite State Machines (FSMs) are often used to implement decision making policies for autonomous systems. In recent years, the use of Behavior Trees (BT) as an alternative policy representation has gained considerable attention. The benefits of using BTs over FSMs are modularity and reusability, enabling a system that is easy to extend and modify. However, there exists few published studies on successful implementations of BTs for industrial applications. This paper contributes with the lessons learned from implementing BTs in a complex industrial use case, where a robotic system assembles explosive charges and places them in holes on the rock face. The main result of the paper is that even if it is possible to model the entire system as a BT, combining BTs with FSMs can increase the readability and maintainability of the system. The benefit of such combination is remarked especially in the use case studied in this paper, where the full system cannot run autonomously but human supervision and feedback are needed.

In the context of highly customized industrial applications, human-machine collaboration systems merge the efficiency and precision of collaborative robots with the adaptability and complex decision-making capabilities of humans. This integration adeptly addresses intricate manufacturing tasks that demand high sensitivity and adaptability. However, the virtual Commissioning of human-machine collaborative design schemes prior to the establishment of such systems presents challenges. These include integrating diverse heterogeneous components, the absence of a unified standard for modeling, and the need for dynamic adjustments to design schemes to enhance Commissioning efficiency across multiple engineers. Moreover, in manufacturing environments where cost and efficiency are critical, there is a demand for lightweight collaborative Commissioning tools that can swiftly resolve issues. To address these challenges, this paper leverages AML standardized modeling capabilities to develop a human-machine collaborative digital twin construction methodology. This methodology is based on meta models, meta-actions, and configurable meta processes. Furthermore, it introduces a granular progressive loading algorithm designed for a cloud-edge operational mode, which, when coupled with multi-view classification techniques, fulfills the requirements of lightweight collaboration in platforms such as web browsers/IPAD/Augmented Reality. The approach is ultimately validated through a case study focusing on battery pack wiring harness assembly units within the new energy battery sector.

We propose EMS (R), a cloud-enabled massive computational experiment management system supporting high-throughput computational robotics research. Compared to existing systems, EMS (R) features a sky-based pipeline orchestrator which allows us to exploit heterogeneous computing environments painlessly (e.g., on-premise clusters, public clouds, edge devices) to optimally deploy large-scale computational jobs (e.g., with more than millions of computational hours) in an integrated fashion. Cornerstoned on this sky-based pipeline orchestrator, this paper introduces three abstraction layers of the EMS (R) software architecture: (i) Configuration management layer focusing on automatically enumerating experimental configurations;(ii) Dependency management layer focusing on managing the complex task dependencies within each experimental configuration;(iii) Computation management layer focusing on optimally executing the computational tasks using the given computing resource. Such an architectural design greatly increases the scalability and reproducibility of data-driven robotics research leading to much-improved productivity. To demonstrate this point, we compare EMS (R) with more traditional approaches on an offline reinforcement learning problem for training mobile robots. Our results show that EMS (R) outperforms more traditional approaches in two magnitudes of orders (in terms of experimental high throughput and cost) with only several lines of code change. We also exploit EMS (R) to develop mobile robot, robot arm, and bipedal applications, demonstrating its applicability to numerous robot applications.

Soft, wearable systems hold promise for a wide variety of new or enhanced applications in the realm of human-computer interaction, physiological monitoring, wearable robotics, and a host of other human-centric devices. Soft sensor systems have been developed concurrently in order to allow these wearable systems to respond intelligently with their surroundings. A recently reported sensing mechanism based on the strain-mediated contact in anisotropically resistive structures (SCARS) is an attractive solution due to its high sensing resolution, low-profile nature, and high mechanical resilience. Furthermore, the resistance-based output provides a simple electronic readout, facilitating its use in a wide variety of applications. However, previous iterations of the sensing mechanism have exhibited stress relaxation and hysteretic behaviors that limit the scope of its use. Here, we report an iteration of the SCARS mechanism that uses silicone-based materials with low mechanical loss in order to improve the sensor signal stability and bandwidth. A new fabrication approach is developed which permits the incorporation of a liquid elastomer adhesive layer while also preserving the SCARS sensing functionality. The silicone-based SCARS sensors exhibited fast stress relaxation response (< 1 s) and reduced cyclic drift properties by more than half that of previously reported designs. A physiological monitoring demonstration is presented, validating that the new sensor design is mechanically resilient to such applications and has potential for use in real-world wearable use cases.
