Abstract: Techniques and apparatus for performing a power-on self-test for a braking system in an autonomous delivery robot are described. One technique includes moving each wheel of the autonomous delivery robot in a first direction in accordance with predefined criteria, while brake module(s) of the braking system are engaged to one or more of the wheels to stop movement of the one or more wheels. A first amount of movement of at least a first wheel that is engaged to a first brake module is determined. Upon determining that the first amount of movement satisfies a predetermined condition, a determination is made that the braking system has failed the test and the brake module(s) of the braking system are kept in an engaged state.

Abstract: A container may include a cargo bay for holding items; a lid able to slide between a closed position to an open position relative to the cargo bay; a check strap operatively connected to the lid and able to move vertically in a first direction toward the lid as the lid slides from the closed position to the open position, and to move vertically in a second direction opposite the first direction as the lid slides from the open position to the closed position; and arms operatively attached to rollers and to one or more tension devices, wherein when the check strap moves vertically in the first direction, the check strap separates the rollers and causes the arms to pull the one or more tension devices, and wherein when the check strap moves vertically in the second direction, the one or more tension devices cause second rotation of the arms.

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.
