Eccentric assembly for walking mechanism

A barrel member of an eccentric assembly, the barrel member comprising:

• a circumferential portion extending in a longitudinal direction;
• and
• a web portion extending inwardly from the circumferential portion and substantially perpendicular to the longitudinal direction, the web portion comprising a cut-out region and an inner periphery outlining the cut-out region;
• the cut-out region including a closed end, and an open end, and the inner periphery having a first inner side and a second inner side oriented diagonally to one another so as to form an angle that opens toward the open end;
• and
• the inner periphery further including a third inner side extending between the open end of the cut-out region and the first inner side, and a fourth inner side extending between the open end of the cut-out region and the second inner side, and the third inner side and the fourth inner side oriented substantially parallel to one another.

A shaft member of an eccentric assembly, the shaft member comprising:

• a tubular portion extending in a longitudinal direction;
• and
• a flange portion extending outwardly from the tubular portion and substantially perpendicular to the longitudinal direction, the flange portion comprising an outer periphery, wherein the flange portion is alterable to adjust an eccentricity of the shaft member in the eccentric assembly;
• the outer periphery including a first outer side and a second outer side oriented diagonally to one another;
• and
• the outer periphery further including a third outer side adjacent to the first outer side, and a fourth outer side adjacent to the second outer side, and the third outer side and the fourth outer side oriented substantially parallel to one another.
