Publication number: 20250359707Abstract: A method for operating an automated food making apparatus having a motor, actuator arm, and an apparatus. The apparatus may be a paddle with flexible fins. The method rotates the paddle with a pin-shaft mechanism to dispense an ingredient placed in a canister, controls the motor automatically based on weight sensor readings, and locates a position of the actuator arm with position sensors. The same motor dispenses ingredients from a plurality of canisters. The method may have a plurality of paddle rotation and weight measurement steps until a target weight is reached. The plurality of paddle rotation steps may be unidirectional or bidirectional paddle rotation. The paddle may be rotated according to one or more paddle rotation algorithms, an error recovery algorithm, or different algorithms based on the amounts of ingredients remaining in the canister. The paddle may be rocked until the target weight is achieved.Type: ApplicationFiled: August 8, 2025Publication date: November 27, 2025Inventors: Deepak Chandra Sekar, Kathirgugan Kathirasen, Brian Richardson, Sanath Bhat, Levi Lalla

Publication number: 20250200499Abstract: A system is disclosed. The system comprises a scale, and a computer coupled to the scale. The computer comprises a processor, and a computer readable medium. The computer readable medium comprises code, executable by the processor, to perform a method. The method can include receiving a fulfillment request associated with one or more items, responsive to receiving the fulfillment request, determining estimated weight data based on the one or more items in the fulfillment request, obtaining actual weight data associated with the fulfillment request for one or more items, the actual weight data obtained using the scale, verifying that the actual weight data corresponds to the estimated weight data, and performing additional processing based on verifying.Type: ApplicationFiled: March 6, 2025Publication date: June 19, 2025Applicant: DoorDash, Inc.Inventors: Harrison Shih, Hamid Sani, Levi Lalla, Agota Sipos, Milind Shah, Derek Bruce Young, Thomas Belluscio

Patent number: 12271859Abstract: A method includes a computer receiving a fulfillment request associated with one or more items. Responsive to receiving the fulfillment request, the computer determines estimated weight data based on the one or more items in the fulfillment request. The computer obtains actual weight data associated with the fulfillment request for one or more items. The computer verifies that the actual weight data corresponds to the estimated weight data. The computer performs additional processing based on verifying.Type: GrantFiled: July 18, 2023Date of Patent: April 8, 2025Assignee: DoorDash, Inc.Inventors: Harrison Shih, Hamid Sani, Levi Lalla, Agota Sipos, Milind Shah, Derek Bruce Young, Thomas Belluscio
