The body structures and motion stability of worm-like and snake-like robots have garnered significant research interest. Recently, innovative serial-parallel hybrid segmented robots have emerged as a fundamental platform for a wide range of motion modes. To address the hyper-redundancy characteristics of these hybrid structures, we propose a novel caterpillar-inspired Stable Segment Update (SSU) gait generation approach, establishing a unified framework for multi-segment robot gait generation.

Soft actuators hold great promise for applications in biomimetic robots, artificial muscles, and drug delivery systems due to their adaptability in diverse environments. A critical aspect of designing thermally responsive soft actuators is to achieve spatially programmable actuation under a global thermal stimulus. Different local actuation behaviors can be encoded in one actuator to enable complex morphing structures for different tasks.

Article Synopsis
- Inching-locomotion caterpillars (ILAR) serve as inspiration for creating 'inch-worm' robots that utilize biomimicry and can adapt to various environments, including natural and extraterrestrial settings.
- A new mathematical method called Multi-Body Dynamics for Inching-Locomotion Caterpillar Robots (MBD-ILAR) is introduced to simulate the movement of these robots and includes calculations for factors like kinematics and dynamics, focusing on specific robot design aspects.
- A case study was conducted to apply this method, which involved developing a graphical user interface to optimize robot actuator choices and validate the simulation results by analyzing how different parameters influence attachment forces and mechanical performance.
