Instructions

1. Run plot_landscape.m and other plotting codes in static_plots to visualize static energy landscapes for obstacle traversal and self-righting shown in figure 4 of main text.
2. Run plot_*.m codes in interactive_plots for interactive figures of potential energy landscapes

Using interactive plots

• Interactive figures can be used to visualize orthogonal cross-sections of potential energy landscape in the space of three system degrees of freedom.
• For example, for beam energy landscape (image below), potential energy landscape is visualized in the space of body forward position x, body roll, and body pitch.
  
• Adjust the slider position to change system state shown in top left panel (and by the green dots on landscape panels).
• System state and plots can be reset to the initial state by right-clicking on the button on top right corner
