Cat Modeling

/**
 * Creates two cat models for flipping. The first is simply two segments
 * connected by a 2-degree-of-freedom (no twist) joint. It exhibits the

 * freedom between the model's two halves. This model exhibits the variable-
 * inertia mechanism of flipping.

    // This model will be able to hunch and wag (see the joints below).

    // Define anterior and posterior halves of the cat
    // ------------------------------------------------------------------------

    // Define joints between bodies (ground and two halves)
    // ------------------------------------------------------------------------


    // Add bodies to the model
    // ------------------------------------------------------------------------


    // Display goemetry
    // ------------------------------------------------------------------------


    // Actuation
    // ------------------------------------------------------------------------
    

    // Print the model

    // ========================================================================
        
    
    // Leg properties
    // ------------------------------------------------------------------------
    
    
    // Define leg bodies
    // ------------------------------------------------------------------------
    
    
    // Define leg joints (i.e., between legs and two halves of cat)
    // ------------------------------------------------------------------------

    
    
    // Add bodies to the model
    // ------------------------------------------------------------------------
    // ...now that we have connected the bodies via joints.

    
    
    // Display goemetry
