Abstract: A pick up and delivery system for use with mobile robots which have a body with a horizontal upper surface and at least one vertical side. The robot has at least one shelf, each of which contains a stop bar containing a retaining device. The system further uses multiple stations, each of which contain at least one pallet retaining surface to contain at least two pallets. The pallet retaining surfaces are provided with a holding device at the pick up area and a holding device at the delivery area. Pallets are used to retain the items being transferred with each of the pallets having a securing device that interacts with the holding device and retaining device. The strength of the holding device at the pick up area is less than the holding device at the delivery area, with the robot's retaining device having a strength between the strength of the holding devices. The mobile robot picks up a pallet from a first station, and delivers the pallet to a second station.

Abstract: An apparatus for building stem wall forms which can be easily deployed by a form laborer to set up stem wall forms at a building site. The apparatus is collapsible for easy deployment and removal from a stem wall form. The preferred embodiment is comprised of a collapsible rectangular center structure coupled to a board holder and a board support arranged in diagonal relation to each other. The board holder allows the apparatus to hang from a first form board and the board support allows a second form board to rest thereon. In use, the apparatus functions by holding opposing form boards of a stem wall form in a parallel relation to each other, so that the form boards can be staked and nailed into place. Once the form boards are staked in place, to create a stem wall form, the apparatus can be collapsed, and removed from the form to be reused again at another location.
