| Abstract | A new approach of ferrrofluid based soft actuator which shows various vertical motions has been introduced in this study. The flexibility and potential of the prototype made, was tested during this thesis by simulation and experimental approach. The simplicity of the design make the system more cost effective and readily made. The soft actuator is made by injecting ferrofluid inside a soft and thin rubber tube commonly used as balloon. The system also consists of six hand winded electromagnets placed at different positions along the side of the tube, whose magnetic field intensity is controlled by changing the duty cycle of the input voltage. The position of the coils as well as the input voltage to the coils are varied which in turn showed different motion of the ferrofluid tube. Both simulation and practical investigation are carried out to show a precised movement of the soft actuator. This research also explores how COMSOL Multiphysics can be used to model different motions of the ferrofluid tube with varying voltage. Numerical results from the COMSOL model shows quite resemblance with the empirical result obtained from the practical modelling. The simulation results helped refinement of the practical model and optimization of the parameters. |
