Abstract: Embodiments generally relate to robots and enabling robots to locate objects in a physical environment. In some embodiments, a method includes charging a radio-frequency identification (RFID) tag with an RFID reader, where the RFID tag is coupled to an object, and where the RFID reader is coupled to a robot arm. The method further includes receiving a plurality of responses from the RFID tag, where each response includes a power value to which the RFID tag was charged and a time value for charging the RFID tag to the power value. The method further includes moving the RFID reader to a plurality of RFID reader positions using the robot arm, where each RFID reader position is associated with one of the responses of the plurality of responses. The method further includes determining a plurality of distances from the RFID reader to the RFID tag based on power values and the time values of the respective responses at the respective RFID reader positions.

Abstract: A lane departure preventing device includes at least one electronic control unit. The at least one electronic control unit is configured to: when there is a likelihood that a vehicle will depart from a traveling lane, calculate a prevention yaw moment, and control a brake actuator such that the prevention yaw moment is applied to the vehicle; acquire a lateral acceleration; determine whether the lateral acceleration is greater than an ideal value by a predetermined value; control the brake actuator such that the braking force matches a target braking force required to apply the prevention yaw moment to the vehicle, when the lateral acceleration is not greater than the ideal value by the predetermined value; and control the brake actuator such that the braking force is less than the target braking force, when the lateral acceleration is greater than the ideal value by the predetermined value.
