Abstract: A transporter. The transporter includes: a first unit; at least one second unit; and a coupler attached between the first unit and the second unit, the coupler coaxially aligned with the coupling axis thereby permitting rotational movement perpendicular to the coupling axis and an auto lock mechanism attached to the coupler for permitting hands free coupling of the first unit and the at least second unit. The transporter may further include at least one articulated joint attached between the coupler and one of the first unit and the second unit.
