However, different material may influence the mass of the flexible link.
Therefore, the selection of materials can also affect resonance.
Therefore, selection materials is also an important factor worthy of consideration during the design process of flexible manipulators.
In addition, the selection of materials is also worthy of consideration during the design process of flexible manipulators for evading resonance.
