Abstract:
A system and method for allowing an operator to switch between remote vehicle tele-operation and one or more remote vehicle autonomous behaviors, or for implementing remote vehicle autonomous behaviors. The system comprises an operator control system receiving input from the operator including instructions for the remote vehicle to execute an autonomous behavior, and a control system on the remote vehicle for receiving the instruction to execute an autonomous behavior from the operator control system. Upon receiving the instruction to execute an autonomous behavior, the remote vehicle executes that autonomous behavior.
Abstract:
A method and apparatus for computing properties of a physical environment is provided, using a plurality of agents forming a distributed network embedded within the environment. The method comprises determining an initiating agent (200), transmitting a signal including a cumulative cost value to neighboring agents (202), and processing the signal at each neighboring agent to augment the cumulative cost value with local information (204). If multiple signals are received, determining which has the best cumulative cost value for generating a new signal (206), then treating the neighboring agent as an initiating agent (208) and transmitting the new signal to neighboring agents (208) and retaining the best augmented cost value in memory (210). Methods further include determining paths using shortest path computations, using dual gradients for aligning agents on a path between two reference agents, and discovering and converging agents on choke points.
Abstract:
A mobile monitoring device for detecting a fire, gas leak, intruder, of other abnormal condition in a house or office, and for alerting a central monitor, fire station, police station, or an occupant who is away from the house or office. The mobile monitoring device comprises a self-propelled movable robot having sensors located thereon; a monitor for receiving signals from the robot and alerting an authorized user accordingly; an automatic communication control unit including a telephone transmitting unit for automatically calling an appropriate party in response to a signal from the robot and for transmitting commands to the robot from an authorized calling party; and an RF remote controller for remotely controlling the robot. The robot is specifically capable of navigating throughout a house or office while using its sensors to detect abnormal conditions. In the event that an abnormal condition is detected, the robot initiates communications with the monitoring means and the automatic communication control unit to thereby alert an appropriate party of the existing abnormal condition. Commands can be provided to the robot either directly through a keyboard on the robot itself, or remotely by way of the RF remote control means or the automatic communication control means.
Abstract:
Systems and methods for using radio frequency signals and sensors to monitor environments (e.g., indoor environments) are disclosed herein. In one embodiment, a system for providing a wireless asymmetric network comprises a hub having one or more processing units and at least one antenna for transmitting and receiving radio frequency (RF) communications in the wireless asymmetric network and a plurality of sensor nodes each having a wireless device with a transmitter and a receiver to enable bi-directional RF communications with the hub in the wireless asymmetric network. The one or more processing units of the hub are configured to execute instructions to determine at least one of motion and occupancy within the wireless asymmetric network based on a power level of the RF communications.
Abstract:
An autonomous vehicle including a chassis, a conveyance system carrying the chassis, and a controller configured to steer the conveyance system. The controller is further configured to execute the steps of receiving steering radius information from a source; and creating steering instructions for the vehicle dependent upon the steering radius information from the source. The source not being from the vehicle itself.
Abstract:
Systems and methods for virtualized computing or cloud-computing network with distributed input devices and at least one remote server computer for automatically analyzing received video, audio and/or image inputs for providing social security and/or surveillance for a surveillance environment, surveillance event, and/or surveillance target.
Abstract:
A robotic work tool system (200) comprising a charging station (210) and a robotic work tool (100), said robotic work tool (100) comprising a position determining device (190) for determining a current position, the robotic work tool (100) being configured to determine that reliable navigation through said position determining device (190) is no longer possible, such as when satellite signal reception is not possible, at a time point (T1) and position and in response thereto generate an obstacle map which gives information on the position of at least one obstacle (260), determine when an area will be shadowed with regards to satellite reception based on said obstacle map, and to schedule operation of the robotic work tool (100) accordingly.
Abstract:

Abstract:
Disclosed are a steering control device of an autonomous vehicle, an autonomous vehicle having the same, and a steering control method of an autonomous vehicle. The steering control method comprises receiving a position of an autonomous vehicle, and a first heading angle of the autonomous vehicle with respect to the north; calculating a second heading angle of the autonomous vehicle toward a tracking waypoint based on the position of the autonomous vehicle, and computing a rotation radius of the autonomous vehicle with respect to the tracking waypoint; calculating a yaw rate based on a speed of the autonomous vehicle and the computed rotation radius, and generating a steering command corresponding to the calculated yaw rate; and compensating for the steering command based on the first and second heading angles.
