Abstract: An apparatus includes a hub, a carrier structure and a first plurality of connective elements. The carrier structure surrounds the hub and holds a plurality of rollers that rotate within the carrier structure about an axis that is orthogonal to an axis of rotation of the hub. The first plurality of connective elements are coupled to the hub and the carrier structure. A connective element of the first plurality of connective elements elastically deforms to absorb an impact experienced by the carrier structure such that the rollers can rotate within the carrier structure while the carrier structure experiences the force.

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.
