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: Primary vehicles having cameras or other sensors generate and transmit instructions for causing secondary vehicles, such as personal delivery devices, to travel on selected courses and speeds. The primary vehicles capture and process images or other data to determine positions or orientations of the secondary vehicle, to detect any obstacles, and to select courses or speeds for the secondary vehicle based on the locations of the obstacles or one or more objectives of a task or function. Alternatively, the secondary vehicles may also capture images or other data, and transmit the images or data to the primary vehicle for processing. The secondary vehicles may include one or more fiducials having visual markings thereon. The visual identifiers are fixed in their orientations with respect to the secondary vehicles, such that positions or orientations of the secondary vehicles may be determined upon detecting the markings within imaging data.
