Abstract: A robotic assistant includes a wheeled base, a storage unit including drawers, a foldable arm connected to a top of the storage unit and including an end of arm tooling (EOAT) connected to a distal end of the foldable arm, an elevation mechanism positioned on the wheeled base and used to move the storage unit up and down, and a control system that receives command instructions. In response to the command instructions, the control system is configured to move the wheeled base, open or close the one or more drawers, actuate movement of the foldable arm and the EOAT to pick up and place external objects from/to a determined location, and control the storage unit to move up/down.

Abstract: According to one aspect, an actuator of a robotic drawer is disclosed. The actuator may include a plurality of articulation components that form an articulated rack. The actuator may include a plurality of pins each coupled to an exterior of one of the plurality of articulation components. The actuator may include a transformer box coupled to a pinion and configured to move along an exterior of the articulated rack as the pinion moves along the surface. The transformer box may include a first guide configured to apply a first force to an arm of each of the pins as the transformer box moves in a first direction. The first force may cause the pin to rotate in a first rotational direction until the arm is fitted into a cam of the articulated rack such that adjacent articulation components are held in a fixed position, causing the articulated rack to extend.

Abstract: A robotic walking assistant includes a wheeled base having a base and one or more position adjustable wheels connected to the base, a body disposed in a vertical direction, positioned on the wheeled base and having a handle, and a control system that receives command instructions. Each of the one or more wheels is slidable with respect to the base between a retracted position and an extended position in a direction that is substantially parallel to a surface where the wheeled base moves. In response to the command instructions, the control system moves the one or more wheels between the retracted positions and the extended positions.
