An autonomous tilting three-wheeled vehicle comprises a pair of front wheels coupled to a tiltable chassis by a mechanical linkage, such that the pair of wheels and the chassis are configured to tilt in unison with respect to a roll axis of the chassis. An electronic controller of the autonomous vehicle controls a tilt actuator to selectively tilt the chassis. Optionally, a steering actuator is coupled to the front wheels and controlled by the electronic controller to selectively steer the wheels. A sensor configured to measure orientation-dependent information may be coupled to the chassis by a gimbal configured to compensate for vehicle tilt. In some examples, the autonomous vehicle comprises an autonomous delivery robot.

A connection system for a house and a vehicle, may include a vehicle door provided in the vehicle to open or close a vehicle entrance through which a passenger enters or exits the vehicle and allowing an internal space of the vehicle to be exposed into the house when authenticated by the house; and a hatch provided in a house entrance on a side wall of the house to selectively couple the house entrance and the vehicle entrance with each other so that an internal space of the vehicle and an internal space of the house are connected to each other in a state that the vehicle door is open when the authenticated vehicle is parked on a side of the house entrance.

A vehicle includes a support structure. The vehicle also includes a side door operable to move relative to the support structure between an open position and a closed position. In the open position of the side door, access to a vehicle interior of the vehicle is provided. In the closed position of the side door, the side door extends across a longitudinal centerline of the vehicle. The vehicle further includes a plurality of pivot members, each pivotably coupled to the support structure at a first end and pivotably coupled to the side door at a second end. The side door is movable between the open and closed positions via pivotal movement of each of the plurality of pivot members relative to the support structure and pivotal movement of the side door relative to each of the plurality of pivot members.
