This Dataset files are the main resource materials for Chapter 2 (design analysis and optimization) and Chapter 3 (motion control based on self-learning) in my PhD thesis. The first sub-folder is about the comparison experiments on two different groups of multi-segment continuum robots, revealing how structure parameters affect the kinematic performances of continuum robots in terms of workspace and dexterity. The second sub-folder is about the construction of deep reinforcement learning framework to realize the model-free control of multi-segment continuum robots. In addition, case study and comparative analysis on a two-segment continuum robot is included.
