Abstract
A mother daughter cart system includes a transportable daughter cart, a moveable mother cart to which the daughter cart is selectively addable and an onboard energy generation system. With the addition of the daughter cart to the mother cart, the mother cart is coupled with the daughter cart for movement as a unit. The daughter cart includes a part support adapted to carry one or more parts, and an electrically powered actuator coupled to the part support and configured, when powered, to selectively impart movement to the part support to manipulate its placement. The energy generation system includes a generator configured to convert energy from the mother cart's movement into electrical energy usable to power the actuator in the daughter cart.
