| مستخلص: | Impaired mobility is one of the major issues in human life, affecting and limiting independent living, especially for older adults. Although many conventional rigid exoskeletons and soft orthoses have been developed to strengthen the human body for workers, and improve the mobility of people with disabilities, there remain many challenges to overcome before we can create an assistive suit for healthy elderly individuals. Advanced wearable assistive devices should have light weight, low cost, high exibility, and high adaptability. This will enable them to fit the user's body while remaining inconspicuous (possibly being embedded with standard clothing), and also provide suffcient mechanical power to maintain effective and safe assistance to the body. To achieve these required features, this thesis describes the study and development of novel artificial muscles based on two potentially disruptive technologies: pneumatically-driven and electrically-driven soft actuators. First, a lightweight, flexible, inexpensive pneumatic actuator, namely Bubble Artificial Muscle (BAM), was developed. BAMs are capable of generating either high contraction or high tensile force, by adjusting their material properties. This provides BAMs with high flexibility, allowing them to be designed to suit the various capabilities of human muscles. An actuation model was developed to predict the real-world performance of BAMs, and a design methodology to maximise BAM performance metrics is presented. A mobility assistance demonstrator was built to investigate how an effective orthosis can theoretically reduce muscle work of a user while walking. BAMs were used to create soft orthoses to assist two human locomotion movements: walking and sit-to-stand transition, providing support forces and assisting the lower limb's motions. However, since the BAM is pneumatically driven, it has a major drawback due to its associated air power source, e.g. a large, heavy, noisy pump or compressor fo |
