Abstract: Examples implementations relate to determining path confidence for a vehicle. An example method includes receiving a request for a vehicle to navigate a target location. The method further includes determining a navigation path for the vehicle to traverse a first segment of the target location based on a plurality of prior navigation paths previously determined for traversal of segments similar to the first segment of the target location. The method also includes determining a confidence level associated with the navigation path. Based on the determined confidence level, the method additionally includes selecting a navigation mode for the vehicle from a plurality of navigation modes corresponding to a plurality of levels of remote assistance. The method further includes causing the vehicle to traverse the first segment of the target location using a level of remote assistance corresponding to the selected navigation mode for the vehicle.

Abstract: An example system includes a delivery vehicle, a sensor connected to the delivery vehicle, and a control system that determines a delivery destination for an object. The control system receives sensor data representing a physical environment of at least a portion of the delivery destination and determines a drop-off spot for the object within the delivery destination by way of an artificial neural network (ANN). The ANN is trained to determine the drop-off spot based on previously-designated drop-off spots within corresponding delivery destinations and includes an input node that receives the sensor data, hidden nodes connected to the input node, and an output node connected to the hidden nodes that provides data indicative of a location of the drop-off spot. The control system additionally causes the delivery vehicle to move to and place the object at the drop-off spot.

Abstract: Described herein are methods and systems for facilitating a wireless power handover. In particular, a controller may cause a first transmitter to provide electrical power to a receiver. The controller may then determine that a handover condition is met and may responsively facilitate a handover to a second transmitter. During this handover, the controller may engage in a phase-determination process to determine first and second phases at which the first and second transmitters should respectively provide electrical power to the receiver. Once determined, the controller may then cause the first and second transmitters to respectively provide electrical power to the receiver at the first and second phases and at substantially the same time. Subsequently, the controller may cause the first transmitter to no longer provide electrical power to the receiver and the second transmitter to continue to provide electrical power to the receiver, thereby completing the handover.

Abstract: An example method may include receiving, from a client computing device, an indication of a target drop-off spot for an object within a first virtual model of a first region of a delivery destination. A second virtual model of a second region of the delivery destination may be determined based on sensor data received from one or more sensors on a delivery vehicle. A mapping may be determined between physical features represented in the first virtual model and physical features represented in the second virtual model to determine an overlapping region between the first and second virtual models. A position of the target drop-off spot within the second virtual model may be determined based on the overlapping region. Based on the position of the target drop-off spot within the second virtual model, the delivery vehicle may be navigated to the target drop-off spot to drop off the object.

Abstract: An example system includes a disk that is rotatable and has a plurality of ferromagnetic elements disposed in a radial array on a surface of the disk; and at least one electro-permanent magnet (EPM) mounted adjacent to the disk such that a gap separates the disk from the EPM. Applying an electric pulse to the at least one EPM changes a magnetic state thereof, thereby generating an external magnetic field that traverses the gap between the disk and the EPM and interacts with a ferromagnetic element of the plurality of ferromagnetic elements, and causing a rotational speed of the disk to change as the disk rotates.

Abstract: Disclosed herein is a method of determining an operational configuration of a wireless power adapter. The method includes determining whether the wireless power adapter is calibrated to supply a legacy device with electrical energy. The method further includes, in response to determining that the wireless power adapter is not calibrated to supply the legacy device with electrical energy, delivering a first power signal to the legacy device via a first electrical coupling member. The method also includes detecting a response of the legacy device to receiving the first power signal, and based on the response of the legacy device, determining an operational configuration of the wireless power adapter. Furthermore, the method includes configuring the wireless power adapter to operate according to the determined operational configuration.

Abstract: Examples implementations relate to navigation path determination. An example method includes receiving, at a computing system, video data showing a demonstration path for navigating a location. The method further includes identifying, using the video data, a set of permissible surfaces at the location, wherein each permissible surface was traversed by the demonstration path. The method additionally includes determining a navigation path for a vehicle to follow at the location, wherein the navigation path includes a variation from the demonstration path such that the variation causes the vehicle to stay within one or more permissible surfaces from the set of permissible surfaces. The method also includes causing, by the computing system, the vehicle to follow the navigation path to navigate the location.
