In this paper, we present a kineto-static analysis on a wrist rehabilitation robot to compensate for joint misalignment between human and robot joints. Since joint misalignment has proved to generate user–device interaction forces, which reduce the comfort and safety of the wearable devices and limit the user’s willingness to use it. The use of compliance and the addition of passive joints for joint misalignment compensation are discussed. In order to study the effect of the initial offset, we find that the initial offset in the direction perpendicular to the forearm causes a larger unwanted force. In addition, the use of the softest compliance can minimize unwanted force by 38% compared to the case without compliance. Furthermore, the effect of the addition of passive joints to the exoskeleton is investigated. From the analysis results, the soft part of the human being is regarded as a passive joint with the ability to compensate for joint misalignment. Moreover, the influence of the soft characteristics of human limbs should be considered when designing a wearable robot. This soft property, causing the movement of the braces, results in reducing the angular range of the wrist. Through the analysis results, we provide effective ideas for joint misalignment compensation to fulfill a comfortable and safer robot design.

Ethical, legal and societal implications (ELSI) in the development of wearable robots (WRs) are currently not explicitly addressed in most guidelines for WR developers. Previous work has identified ELSI related to WRs, e.g., impacts on body and identity, ableism, data protection, control and responsibilities, but translation of these concerns into actionable recommendations remains outstanding. This paper provides practical guidance for the implementation of ELSI in WR design, development and use. First, we identify the need for domain-specific recommendations against the context of current ELSI guidance. We then demonstrate the feasibility and usefulness of taking a domain-specific approach by successively transforming currently identified ELSI into an action-guiding flowchart for integration of ELSI specific to the different stages of WR development. This flowchart identifies specific questions to be considered by WR development teams and suggests actions to be taken in response. By tailoring ELSI guidance to WR developers, centring it on user needs, their relation to others and wider society, and being cognizant of existing legislation and values, we hope to help the community develop better WRs that are safer, have greater usability, and which impact positively on society.

Microwave cutting glass and ceramics based on thermal controlled fracture method has gained much attention recently for its advantages in lower energy-consumption and higher efficiency than conventional processing method. However, the irregular crack-propagation is problematic in this procedure, which hinders the industrial application of this advanced technology. In this study, the irregular crack-propagation is summarized as the unstable propagation in the initial stage, the deviated propagation in the middle stage, and the non-penetrating propagation in the end segment based on experimental work. Method for predicting the unstable propagation in the initial stage has been developed by combining analytical models with thermal-fracture simulation. Experimental results show good agreement with the prediction results, and the relative deviation between them can be <5% in cutting of some ceramics. The mechanism of deviated propagation and the non-penetrating propagation have been revealed by simulation and theoretical analysis. Since this study provides effective methods to predict unstable crack-propagation in the initial stage and understand the irregular propagation mechanism in the whole crack-propagation stage in microwave cutting ceramics, it is of great significance to the industrial application of thermal controlled fracture method for cutting ceramic materials using microwave.
