Objective:
The objective of this assignment is to design, fabricate and evaluate an origami-based soft pneumatic actuator. The student will explore the use of origami-based design principles to achieve enhanced actuator performance, and expand the potential applications specifically for endoscopic applications.
Description:
The student will begin with a literature review to understand existing approaches in origami-inspired soft robotics. Using CAD software, they will design an actuator incorporating origami structures and simulate its mechanical behaviour under pneumatic pressure using finite element analysis (FEA). The fabricated actuator, produced through methods such as 3D printing, laser cutting, or silicone molding, will then be experimentally tested for key performance metrics, including deformation, force output, actuation speed and bending angle. Finally, the results will be analyzed to refine the design, validate the findings against simulations, and compile the outcomes into a comprehensive thesis report.
Background of the student:
The candidate should ideally have a background in mechanical engineering, biomedical engineering, or a related field. Familiarity with the following software and skills is advantageous:
- CAD software: Solidworks, Fusion 360, or similar for design
- FEA: ANSYS, COMSOL, or Abaqus for simulations
- Fabrication Tools:
- Experience with 3D printing, laser cutting or silicone moulding for prototyping
- MATLAB or Python for processing experimental data and creating plots
