On uneven ground, legged robots have the potential to be a walking machine. Theo Jansen's mechanism, which consists of eleven bar linkages, reproduces a smooth walking pattern known as gait. Parallel motions are commonly used in heavy machinery and have recently been highlighted in a biological motion model. Due to the singularity problem, the close-loop connection just gives a designed end- effector's trajectory, which is believed to be less changeable. The singularity on the modified Theo Jansen mechanism was addressed in this study by introducing the parametric orbit as a new freedom point at the joint center, and multi body dynamics were used to examine its kinematics and dynamics (MBD). In the numerical simulation, the mechanism's extensibility in terms of gait trajectory flexibility was clearly established, resulting in novel functional gait trajectories controlled by two control parameters that modify the form of the parametric oval in the joint center.

Microstructure Atlas of P91 Steel

This book highlights the qualitative and quantitative sequential changes in microstructure of P91 steel under various stress and temperature conditions. The P91 alloy is an established material used under elevated temperature and stress in the components of thermal power plants. Temperature and stress levels for laboratory experimentation have been selected based on the true operating condition of a boiler. This book describes both full length as well as interrupted tests that were performed under given parameters. Subsequently, the microstructures, bulk hardness and NDE parameters (magnetic and non-linear ultrasonic) have been evaluated. For reliable data, the microstructures have been observed at different regions of creep exposed samples by different characterization techniques. This has been further followed by drawing co-relation between specific features like precipitate size variation with creep strain / creep time and so on. Given the contents, this book will be a useful reference for researchers and professionals working in the area of materials especially in thermal power plants.
