Abstract: Systems and methods of manipulating/controlling robots. In many scenarios, data collected by a sensor (connected to a robot) may not have very high precision (e.g., a regular commercial/inexpensive sensor) or may be subjected to dynamic environmental changes. Thus, the data collected by the sensor may not indicate the parameter captured by the sensor with high accuracy. The present robotic control system is directed at such scenarios. In some embodiments, the disclosed embodiments can be used for computing a sliding velocity limit boundary for a spatial controller. In some embodiments, the disclosed embodiments can be used for teleoperation of a vehicle located in the field of view of a camera.

Abstract: Methods and systems are described herein for enabling aerial vehicle navigation in GPS-denied areas. The system may use a camera to record images of terrain as the aerial vehicle is flying to a target location. The system may then detect (e.g., using a machine learning model) objects within those images and compare those objects with objects within an electronic map that was loaded onto the aerial vehicle. When the system finds one or more objects within the electronic map that match the objects detected within the recorded images, the system may retrieve locations (e.g., GPS coordinates) of the objects within the electronic map and calculate, based on the coordinates, the location of the aerial vehicle. Once the location of the aerial vehicle is determined, the system may navigate to a target location or otherwise adjust a flight path of the aerial vehicle.

Based on the distance travelled after each instance of the acceleration profile is executed, an instance of when the target location is reached may be determined.

Abstract: The controller of the present disclosure enables an autonomous vehicle to travel at increased speed in a high performance driving behavior region (HPDBR), such as when a likelihood of the autonomous vehicle driving off course or colliding with other vehicles and/or people at the work site is low.

The controller may cause, based on determining whether an HPDBR-related risk exists, an autonomous vehicle speed control operation to be performed.

Abstract: An electronic device such as a head-mounted device may have a transparent layer supported by head-mounted support structures. A light source may emit light through the transparent layer, and an optical sensor may detect light that has reflected from an external object, such as to track the external object.

An opaque masking layer may be coupled to the transparent layer to absorb the stray light and further reduce the amount of stray light that reaches the optical sensor.
