For example, a system may include a radome to be attached to a vehicle bumper fascia; an antenna array on a Printed Circuit Board (PCB), the antenna array is between the PCB and the radome, the antenna array comprising a Transmit (Tx) antenna configured to transmit Tx radar signals via the radome and the vehicle bumper fascia, and a receive (Rx) antenna configured to receive Rx radar signals based on the Tx radar signals; and an absorbing spacer in a spacer area between the PCB and the radome, the spacer area separating the Tx antenna from the Rx antenna, the absorbing spacer configured to absorb reflected signals formed by reflection of the Tx radar signals from the vehicle bumper fascia.

An autonomous robot vehicle in accordance with aspects of the present disclosure includes a conveyance system and a compartment coupled to the conveyance system. The conveyance system autonomously drives the autonomous robotic vehicle between one or more storage locations and one or more delivery locations. The compartment receives one or more items stored at the one more storage locations. The compartment includes a temperature control module configured to maintain the compartment within a predetermined temperature range to provide temperature control for the one or more items as the conveyance system drives between the one or more storage locations and the one or more delivery locations.

A radar unit assembly for a vehicle includes a vehicle body structure and a grille assembly mounted to the vehicle body structure. A radar unit is connected to the grille assembly.

A vehicle body rear structure includes: a rear panel provided in a rear part of a vehicle body; a bumper beam attached to a structural member provided in the rear part of the vehicle body; a sensor holding member attached to the rear panel; and a sensor attached to the sensor holding member and configured to detect surrounding information on a rear side of a vehicle, wherein an entirety of the sensor is positioned more forward than a rear end of the bumper beam, lower than a lower end of the bumper beam, and higher than a departure angle face.

An autonomous floor cleaning robot includes a transport drive and control system arranged for autonomous movement of the robot over a floor for performing cleaning operations. The robot chassis carries a first cleaning zone comprising cleaning elements arranged to suction loose particulates up from the cleaning surface and a second cleaning zone comprising cleaning elements arranged to apply a cleaning fluid onto the surface and to thereafter collect the cleaning fluid up from the surface after it has been used to clean the surface. The robot chassis carries a supply of cleaning fluid and a waste container for storing waste materials collected up from the cleaning surface.

Disclosed is a system for controlling the visual appearance of a sensor cover on a vehicle. The system includes a processor, and a sensor cover display disposed on the sensor cover and in communication with the processor. A color-changing element is included in the sensor cover display. The processor is configured to provide a signal representing a desired color or pattern to the color-changing element, and the color-changing element is configured to render the desired color or pattern.

A contact detection apparatus includes a bumper beam, an absorber, a contact detection sensor, a tube holder, a cover, and first and second protrusions. A pressure tube is held in a groove of the tube holder. The cover is attached to a front end of the tube holder. A pressing member of the cover is disposed inside an opening groove of the groove and in front of the pressure tube. The pressure tube includes first and second protrusions on its outer periphery. The first protrusion projects in a frontward direction, faces the pressing member in frontward and backward directions, and has a pair of upper and lower surfaces inclining in respective directions to come closer to each other as the upper and lower surfaces extend in the frontward direction as seen in a vehicle width direction. The second protrusion is disposed above the first protrusion in an upward direction.

A contact detection apparatus includes a bumper beam, an absorber, a contact detection sensor, a tube holder, and a cover. The absorber is disposed in front of and adjacent to the bumper beam. The contact detection sensor includes a pressure tube and outputs a signal in accordance with a change in pressure of the pressure tube. The tube holder is a part of a front end of the absorber and has a groove holding the pressure tube therein. The cover is attached to a front end of the tube holder and includes a body covering a front face of the tube holder and a pressing member disposed in front of the pressure tube. An upper end of a rear face of the pressing member is disposed at a more backward position than a lower rear end of the pressing member.

A bumper spoiler structure includes: a bumper panel provided in a bumper of a vehicle; a bumper spoiler capable of advancing and retreating relative to the bumper panel by being moved in an inside-outside direction of the vehicle; a first actuator movable in the inside-outside direction and configured to move the bumper spoiler in the inside-outside direction; a first controller configured to control the first actuator; a second actuator configured to move the bumper spoiler and the first actuator in the inside-outside direction; and a second controller configured to control the second actuator. When at least one of the first actuator and the first controller is lost in a deployed state in which the bumper spoiler protrudes with respect to the bumper panel, the second controller moves the bumper spoiler and the first actuator toward an inner side of the vehicle by using the second actuator.

A vehicle collision determination system includes an acceleration sensor fixedly positioned to a front end of the vehicle and configured to measure acceleration at a fixed position, a detector configured to detect whether the vehicle collides using the acceleration measured by the acceleration sensor, a metrics setting unit configured to set at least one metric using the acceleration measured by the acceleration sensor when the detector detects collision of the vehicle, and a determiner configured to determine whether an object that has collided with the vehicle is a pedestrian using the at least one metric set by the metrics setting unit.
