In the context of the current increase in demand for E-waste recycling, this thesis proposes a solution for the recycling of used cell phones to dismantle used cell phones with the necessary mechanical motion provided through a Stewart Platform. A digital model of the platform is constructed encompassing the kinematics and dynamics properties of the system to assess the feasibility of the solution providing the required trajectory of the end effector to complete the translational and rotational motions necessary for disassembly. A series of experiments were conducted to measure the maximum force required to disassemble mobile phone screens, which in most cases is the largest force in the disassembly process to inform the design of the disassembly platform. The resulting analyses showing the effectiveness of the method are provided followed by suggested future work to create a complete disassembly system based on the investigated framework.
