A robotic delivery vehicle may be capable of providing sufficient insulation for perishable items without sacrificing the delivery robotic delivery vehicles' travel range by using passive cooling configurations. Passive cooling configurations may include improving the insulation performance of the robotic delivery vehicle as well as incorporating cooling elements. The robotic delivery vehicle may include a cargo bay liner and a vehicle lid that covers and encloses a cargo bay from the external environment. The cargo bay liner may include an insulated bottom and at least one insulated wall extending from the insulated bottom, wherein the at least one insulated wall and the insulated bottom define a cargo volume. The lid may define a lid volume and is configured to selectively enclose the cargo volume.

An item dispensing vehicle with selectively controllable bays is described herein. In an example, a system includes a first bay configured to retain a first set of items on a first set of conveyor belts that ends at a first opening. The system also includes a second bay configured to retain a second set of items on a second set of conveyor belts that ends at a second opening. The system additionally includes a divider positioned between the first bay and the second bay and a door comprising a third set of conveyor belts and operable between one or more open positions and a closed position. The door blocks the first opening and the second opening in the closed position. The first opening and the second opening can be at least partially unblocked in an open position of the one or more open positions.

A wearable device may compress the skin of a user when worn, which may affect values determined using sensors of the device. To determine the effect of skin compression on the values, a time-of-flight signal, images, or frames of video data that depict a portion of the body having indentations from wearing the device may be acquired. Characteristics of the images, such as shadows associated with the indentations, may be processed using a machine learning algorithm or mathematical function to determine a depth of various portions of the indentations. Depth data from the time of flight signal may be used to refine or modify these determined depths. The amount of skin compression associated with the indentations may be used to modify signals acquired using sensors, or output a recommendation for a band or other method for securing the device.

Systems for determining elevations of skin features

A mobile robot (for example, a robot used for package deliveries, among other purposes) may include a mast with a visual indicator for providing visibility to drivers and pedestrians in the environment proximate to the mobile robot. The mast may produce a large moment arm, which may result in the mast being more likely to break off from the robot. To mitigate or prevent damage to any components of the mast and/or the mobile robot when such a breakage occurs, described herein is an omni directional breakage joint that is used to connect the mast to the mobile robot. The omni directional breakage joint comprises multiple ball and socket joints that provide structural support between the mast and the mobile robot, while simultaneously allowing for a certain movement freedom of the mast and allowing for the mast to easily be engaged and disengaged from the mobile robot without causing damage to any components.
