In recent years, soft actuator has been extensively developed in robotic research. This type of robot is expected to work with human with its flexible and adaptable advantage. The actuator material is soft, light, safe and high compliant. Due to these factors, soft McKibben is of interest as an actuator for this research for bending application. This paper introduces a variant bending analysis of a soft body manipulated using soft McKibben actuators. A series of 1.80 mm width with the length of 120.0 mm McKibben actuator is used to control the bending motion. The design consists of four McKibben actuators arranged in parallel and compacted in a soft body. The bending behavior was evaluated using an experimental test with a variety of pneumatic input pressure and length section on the actuator. The experiment showed that the bending angle was influenced by the segmentation length of the actuator, where the segmentation length and increased input pressure also allow more bending on the actuator. The actuator with lot of section gave more bending response compared to the actuator with lesser section. With the performance exhibited from this study, McKibben actuator can be applied in a wider use for continuum manipulator.
The Ministry of Housing and Local Government (KPKT) initiated Safe City Program in August 2004 as a move towards creating a safe communities and environment in urban areas to improve public quality of life. It served as a crime prevention measure in ensuring the crime rate in the city can be reduced and enables the residents to live, comfortably and safely without fear. To implement this program, each municipal council’s department of town and country planning lead the effort by designing a safe environment and reduce the chance to commit crimes. This study aims to evaluate public awareness of safe city program implementation in Johor Bahru district. Community engagement is important to make sure local community fully aware about safe city program and help in making the program successful. To determine the level of awareness, 80 questionnaires were distributed to public community around affected areas. The data were then analysed using spread sheet program and SPSS. Result has shown that public awareness is closely related with physical visibility for each safe city initiatives. The significant of the study is to provide strategy to increase public awareness for the continuation of safe city program in the future.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
