A support platform assembly is disclosed. The support platform assembly provides a level surface on which a ladder can be supported, and includes an extendable platform, a first set of legs and a second set of legs. The extendable platform includes a first plate having a flat top surface and a second plate having a flat top surface, the second plate being slidable relative to the first plate between a retracted position and an extended position such that a length of the platform increases as the second plate slides from the retracted position to the extended position. The first set of legs are pivotably coupled to a bottom surface of the first plate, and the second set of legs are pivotably coupled to a bottom surface of the second plate, the first and second sets of legs being configured to vertically support the platform.

A brick laying system where an operator such as a mason works proximate a moveable platform having a robotic arm assembly, a mortar applicator with a mortar transfer device, and a brick transfer device to build structures. The robotically assisted brick laying system may also contain a stabilizer having a disturbance sensing and a disturbance correcting component that provides compensation for disturbances caused by load shifting, movement of the platform, wind, operator movement, and the like. In addition, the robotically assisted brick laying system has a sensing and positioning component for controlling placement of the moveable platform and robotic arm assembly. The interoperability of the system with a mason or skilled operator removes much of the manual labor component of brick laying, allowing the mason more time to focus on craftsmanship and quality, thus improving the end product and the overall working conditions of the mason.

A step stool includes an inner frame, an outer frame, an actuator, and a coupler. The inner frame includes two inner pillars, and the outer frame includes two outer pillars attached to a platform near opposite ends of the platform and configured to receive the two inner pillars. The actuator is coupled to one of the two inner pillars and one of the two outer pillars, and is operable to raise the outer frame relative to the inner frame. The coupler couples the two outer pillars to each other to evenly lift the opposite ends of the platform when the actuator raises the outer frame.
