Soft Robots, robots that are constructed out of soft materials or using compliant actuation methods, can operate safely in complex environments without fear of damaging their surroundings or themselves. However, the soft materials and structures can be imprecise and difficult to control. We then developed a discretized constant-curvature model to predict the behavior of planar bending actuators, both under tip load and while pressurized internally. We experimentally verified this model under a range of configurations, using the model to perform open-loop inverse kinematics. These techniques represent a meaningful advancement in understanding and improving soft actuators, allowing them to move with speed and precision while resisting external forces.

Many studies have been conducted in the manufacturing industry to support the cause analysis and early recovery of production line shutdowns caused by machine failures. However, methods such as simple anomaly detection are not effective against large machines with complex behavior. In this study, we propose a method for such machines to show the estimated causes of failure by combining log text files and sensor data, which record software behavior and hardware status, respectively. The proposed method is twice as accurate as methods with only software logs or sensor data, and achieves explainability of the results.
Thanks to the miniaturization and flexibility of various sensors, wearables have been broadly applied in many areas, such as sports science, medical informatics, rehabilitation, etc. Researchers are eager to deeply ex...

Soft robotics holds enormous promise for a wide class of applications. However, system controllability, bandwidth, portability, and energy efficiency of soft robot power supplies are often inadequate. Soft robotics desperately needs improved solutions to drive soft actuators either pneumatically or hydraulically. This research paper offers a contribution to bridge this gap. It deals with small-scale power supplies for hydraulically-driven soft robots based on fluidic elastomer actuators in the power range 5-400 W. A design procedure for such power supplies is developed with an emphasis on high-bandwidth control. The performance requirements are established based on a literature survey, and design alternatives are discussed. Then, a prototype consisting of a 0.102 cm(3)/rev positive-displacement, external gear pump directly driven by a 70 W brushless dc motor is built and experimentally characterized. control of the targeted soft robots results possible because the proposed power supply has high-bandwidth varying between about 12 and 30 Hz (i.e., well above the actuators' mechanical frequency). The power supply's energy efficiency is also measured, and areas for its improvement are identified. The proposed solution is feasible, applicable to autonomous soft robots, scalable to the power levels of interest, and possibly useful for both tethered soft robots and rigid/semi-rigid robots.

In off-road environments, the assessment and classification in travers-able and non-traversable areas is a challenging task. Not only does the drive-ability depend on the vehicle's state in combination with the environmental geometry, but also the assessment is complicated by noisy and wrong sensor data. Thereby, faulty evaluation may lead to severe harm to goods or people since either safety issues or reliability problems are caused. While for the control part behavior-based systems proved to be suitable due to their inherent robustness against unforeseen situations, robust perception is still an unsolved problem leading to severe system failures. This paper faces the perception problem by introducing a new data quality-based perception module based on the integrated Behavior-Based control (iB2C) architecture. Therefore, a new concept of data quality in behavior-based systems and methods for quality aware data fusion are developed while taking advantage of the modularity, extensibility and traceability of the existing architecture.
