  • Publication number: 20200286192
    Abstract: A buffered order management system that allows restaurant employees and robots to operate together without the need for waiting for each other or getting in each other's way with the use of input and output tray buffers. Vision based checks are used to detect manual loading errors to prevent disruptions in robot operation while reducing need for employees to watch over the robot performing tasks continually. Weighing stations are used to detect presence and check weights of items plated into meal tray assemblies ensuring that they are within control limit quantities as per order recipes. Intermediate buffers are used when multiple stations are needed with automated and manual meal assembly tasks to allow robots and employees to work loosely coordinated reducing employee stress but higher efficiency of robots and high productivity for the entire restaurant.

  • Patent number: 10589423
    Abstract: A robot vision supervisor system for use with industrial robots being placed with average home consumers or at restaurants that is capable of guiding the robot to its homing position for initial homing or when a loss of reference has occurred. Further the robot vision supervisor is able to detect presence of unidentified foreign objects in the workspace and guide the robot to navigate around and prevent collisions. Image processing algorithms are used with primary, orthogonal and cross camera arrays to increase reliability and accuracy of the robot vision supervisor. Lookup tables of images are captured and stored by controller for discretized positions in the full robot workspace when robot is in known good calibration to compare with images during regular operation for detecting anomalies.

  • Publication number: 20200054175
    Abstract: A food assembler device that works on sandwich prep table to assemble custom orders in a restaurant utilizing a robot and various attachment tools to collect ingredients from hot and cold containers based on online or manually input orders via a graphic user interface. The food assembler device does not contact any food ingredients and needs minimal cleaning. The food assembler device can be assembled with plurality of robots working together on larger food prep tables and placed along an assembly line using means to increase thruput by coordination of ordering systems, on board computers, controllers, smart weight measuring smart boats, conveyors with sequence and ingredient matrix optimization with dynamic batch size of orders.

  • Patent number: 9643324
    Abstract: A modular robot mechanism utilizing fixed drives, power sources, power delivery cables and electrical components for 4 or more axes in a protective enclosure while making it possible to provide spatial positioning and tilting degrees of freedom to an end effector suitable for using in a consumer product. Furthermore a robotic head mechanism is disclosed that creates additional degrees of freedom or states by combination of existing axes with spring loaded lock mechanisms eliminating need for conventional electrically actuated solenoid or pneumatic grippers making it possible for use as a home appliance. A method to control the robot mechanism and additional axis utilizing a matrix to decouple the input position to the remote actuator and Cartesian motion produced at the end effector.

  • Patent number: 7331750
    Abstract: A parallel robot or parallel kinematics mechanism is provided for uses such as robotics or machining. The mechanism comprises a fixed base, a main arm, and a first and second support arm to position and orient an object in a cylindrical space with at least three degrees of freedom and retained inclination. The main arm includes an end component for supporting the object and linkage means to retain the inclination of the end component with respect to the base for all positions and orientations of the end component. The mechanism advantageously provides a large cylindrical workspace and a small footprint and is capable of moving an object at high accelerations and speeds. The mechanism can be equipped with an additional motor to orient an object, thereby providing the mobility of a SCARA robot. Alternatively, it can be equipped with passive transmission means that allow for an object to be displaced in parallel to itself.
