A 2 Segment Spring Damper Loaded Leg Model Used For Simulation B 2.1 model based on the core characteristics of the hardware prototype (see below), we implemented a 2 segment leg model with a passive spring damper element at the (knee )joint (figure3a). this numerical model is a modified version of the 2 segment leg proposed in rummel and seyfarth (2008) with an additional damper inserted in parallel to the. The simulation results indicate that an adjustable and viscous damper is desired to reject perturbations of the system’s total energy due to variations in the drop height. we examined how our predictions from the numerical simulation relate to hardware experiments (fig.1c). we sep fig. 1: (a) 2 segment leg model with parallel spring damper. To obtain the kinematics of the robot, this study uses the spring loaded inverted pendulum (slip) model to simulate a two legged robot’s gait in 2d, by capturing the dynamics of a point mass at the top of spring damper legs. the simulation is developed in python, and a script for animating the locomotion of the system is also included. The simulink model uses signal connections, which define how data flows from one block to another. the simscape model uses physical connections, which permit a bidirectional flow of energy between components. physical connections make it possible to add further stages to the mass spring damper simply by using copy and paste.
