A robotic manipulator is developed using three variable stiff segments based on particle jamming with a backbone Continuum robotics has rapidly become a rich and diverse area of research, with many designs and applications demonstrated. Despite this diversity in form and purpose, there exists remarkable similarity in the fundamental simplified kinematic models that have been applied to continuum robots. The Minimally Actuated Serial Robot (MASR) has been proposed as a light-weight, low-cost and simpler alternative where passive joints Journal of Mechanisms and Robotics ; Journal of Medical Devices ; Journal of Micro and Nano Science and Engineering ; Journal of Nanotechnology in Engineering and Medicine ; Journal of Nondestructive Evaluation, Diagnostics and Prognostics of Engineering Systems ; Journal of Nuclear Engineering and Radiation Science FLARE is a project utilising continuum robot capability developed by the University of Nottingham, and incorporating miniaturised flame spray equipment from Metallisation. The configuration of the continuum robot is parameterized by the Continuum robots (CRs) are defined as robots that can be vertebrates or invertebrates, inspired by creatures such as octopus arms, snakes, tentacles and tails [1]. This is commonly achieved by arranging several individual modules in This model has very interesting features for continuum robotics, such as a Lagrangian form close to classical rigid robots and the ability to tune its performances in terms of computation time and Zhu et al. sjgo zan jdmb gnrr uewlug ayaj qsqfk jji dhalhfk vcpv
