Abstract
Purpose
Passively compliant underactuated mechanisms are one way to obtain the gripper which could accommodate to any irregular and sensitive grasping object. The purpose of the underactuation is to use less active inputs than the number of degrees of freedom of the gripper mechanism to drive the open and close motion of the gripper. Another purpose of underaction is to reduce the number of control variables.
Design/methodology/approach
The underactuation can morph shapes of the gripper to accommodate different objects. As a result, the underactuated grippers require less complex control algorithms. The fully compliant mechanism has multiple degrees of freedom and can be considered as an underactuated mechanism.
Findings
This paper presents a new design of the adaptive underactuated compliant gripper with distributed compliance. The optimal topology of the gripper structure was obtained by optimality criteria method using mathematical programming technique. Afterwards, the obtained model was improved by iterative finite element optimization procedure. The gripper was constructed entirely of silicon rubber.
Originality/value
The main points of this paper are the explanation of the development and production of the new compliant gripper structure.

Abstract
Purpose
This study aims to offer a holistic halal cosmetic consumption framework by describing the current knowledge about halal cosmetics and presenting new directions for future research.
Design/methodology/approach
The theory, method and context–attributes, decision and outcome systematic review framework was used in this study. This study addresses the halal cosmetics literature published in the Scopus database: nonpredatory journals between 2010 and 2021.
Findings
This study found seven antecedent categories that affect four halal cosmetics consumption decisions. Those decisions led to three outcomes. In addition, behavioral theories were identified as the most frequent theory used to explain this phenomenon in personal and business settings.
Originality/value
To the best of the authors’ knowledge, this is the first systematic review of halal cosmetics consumption. This study explores the relevant theories, contexts, methods, antecedents and consumer decisions. Therefore, this study offers important insights into this phenomenon.
