1. An ambulatory system comprising:
- a beam assembly;
a first leg assembly coupled to the beam assembly, the first leg assembly configured to support the beam assembly and to move in a first direction while coupled to the beam assembly;
a second leg assembly coupled to the beam assembly, the second leg assembly configured to move in a second direction while coupled to the beam assembly;
a carriage configured to support a load and coupled to the beam assembly, the carriage further configured to move the load in a third direction, the third direction not parallel to first direction or the second direction; and
a control mechanism for displacing the carriage, first leg assembly and second leg assembly along the beam assembly, the control mechanism configured to move the first leg assembly, the second leg assembly, and the carriage based on a position of the first leg assembly or the second leg assembly.

Abstract
An ambulatory vehicle having legs and configured for transporting a load is disclosed. The ambulatory vehicle includes a load that is able to shift the center of gravity of the ambulatory vehicle along a transverse axis and a longitudinal axis of a beam assembly. Additionally, leg assemblies of the ambulatory vehicle are configured to exchange places along the length of the beam assembly. Further, the vehicle is able to perform a number of gaits including a slow stable gait and faster dynamic gaits comprising striding, trotting, and bounding. The ambulatory vehicle is able to navigate rough terrain and steep slopes and navigate submerged.

8. A method for moving a beam assembly, comprising:
-
supporting a beam assembly using a first leg assembly and a second leg assembly, the first leg assembly including a first leg in contact with a surface, the second leg assembly including a second leg in contact with the surface; retracting the second leg such that the second leg is not in contact with the surface; moving the second leg assembly from a first position to a second position along a first axis of the beam assembly; displacing a load from a first position to a second position along a second axis of a beam assembly to maintain a center of gravity of the ambulatory vehicle over the first leg assembly; and extending the leg of the second leg assembly to contact the surface. - View Dependent Claims (9, 10, 11, 12, 13, 14)

20. A method for moving a beam assembly, comprising:
-
supporting a beam assembly using a first leg assembly and a second leg assembly, the first leg assembly including a first foot assembly in contact with a surface, the second leg assembly including a second foot assembly in contact with the surface; changing a position of the second leg such that the second foot assembly is above the first foot assembly and in about the same vertical plane as the first foot assembly; moving the second foot assembly from a first position, over the first foot assembly, and to a second position along a first axis of the beam assembly; and extending the leg of the second leg assembly to place the second foot assembly in contact the surface. - View Dependent Claims (21, 22)
