Abstract: A mechanical design for a braking system of a delivery device is described. The braking system includes one or more brake modules. Each brake module is configured to engage a different wheel of the delivery device to stop movement of the wheel when power to the brake module is less than a threshold. Each brake module includes: an electromagnet; a magnetic plate; a pawl configured to engage a wheel to stop movement of the wheel; a solenoid comprising a solenoid pin, the solenoid pin having a first end coupled to the magnetic plate and having a second end coupled to the pawl, and a manual override mechanism that is configured to allow movement of the wheel when the power to the brake module is less than the threshold. The brake module is configured to disable the manual override mechanism when the power to the brake module is greater than or equal to a threshold.

Abstract: Point-of-sale systems may include stations having interactive monitors mounted at specific heights and angles that permit such monitors to be viewed and interacted with by an associate or a customer. Some point-of-sale systems may include two stations, each having a monitor aligned in opposite directions, a user of one monitor may not view the other monitor, and vice versa. The point-of-sale systems may also include instrument readers (e.g., credit card readers or NFC readers) for recognizing payment instruments of customers and identifying the customers based on the payment instruments. Each of the monitors and instrument readers may be linked by cables to computer devices that are securely housed in a chamber above which the monitors are mounted. The monitors and other components are installed in a modular fashion, and may be independently installed or replaced without requiring an installation or replacement of the entire point-of-sale system.
