A medical robotic system includes an entry guide with articulatable instruments such as surgical tools and a camera extending out of its distal end. The camera instrument is manipulatable by a camera manipulator, which has a first mechanism for pivoting a focal point of the camera instrument about a pivot of the camera instrument and a second mechanism for positioning the pivot within a three-dimensional space in response to translational commands received from one or a coupled pair of input devices. The system also includes a controller which is configured to receive sensed movement of the input devices, and cause actuation of the first mechanism in response to the sensed movement if the system is in an orientational mode and cause actuation of the second mechanism in response to the sensed movement if the system is in a translational mode.

In a method for controlling a robot arm, which is particularly suitable for use in medical applications, a robot arm (10) with a redundant number of joints is used. A torque acting in at least one joint (12a, 12b) is sensed. By means of a control device, the torque acting in this joint (12a, 12b) is controlled to become substantially 0.

The invention relates to a method of transferring required messages for acquiring a temporary MAC address in a wireless local area network. In a first device in the local area network, a first identifier is determined to identify the first device. A message comprising the first identifier is transmitted from the first device to a second device to arrange a temporary MAC address. A response message relating to the acquisition of the MAC address and comprising the first identifier is transmitted from the second device to the first device. The first device identifies on the basis of the first identifier that the response message is intended for it.

A method is proposed for automatically moving a vehicle (10, 50) from a handover zone (18) to an assigned parking place (24) within a predefined parking space (20) and for automatically driving the vehicle (10, 50) out of a parking space and moving said vehicle to a pick-up zone (19), wherein the vehicles (10, 50) travelling within the predefined parking space (20) are located by means of a parking place monitoring system comprising at least one sensor unit (30) arranged in a stationary manner and information about the current vehicle position is transmitted to a central control unit (15). The central control unit (15) transmits information to the vehicle (10, 50) so that the vehicle (10, 50) can be guided autonomously within the parking space (20) along a trajectory (40, 45) based on the information. According to the invention, the sensor units (30) are arranged such that certain regions (32) of the parking space are monitored with a high accuracy by the sensor units (30) and other regions of the parking space (31) are monitored with a lower accuracy by the sensor units, wherein overlapping regions (42, 44) of trajectories of other vehicles are determined with the trajectory of the central control unit (15), and the trajectory (40, 45) is adjusted such that an overlapping region (42, 44) in a region (32) of the parking space (20) which is monitored with high accuracy by the sensor units (30) comes to rest.

A satellite deployment system has a plurality of releasable dispenser modules that are attached to each other with each module carrying satellites. Each dispenser module acts as an individual final stage with its own propulsion unit and deploys a subset of satellites to the appropriate altitude and orbit. Since each dispenser module can deploy its satellites far from other dispenser modules, the risk of collision among the satellites is greatly reduced, which allows a large number of satellites to be launched in a safe, timely and cost-effective manner.

A method for entering a preceding vehicle autonomous following mode includes the steps of registering and identifying at least one preceding vehicle in front of a host vehicle by at least a first and a second sensor device, comparing the preceding vehicle with vehicle data in a remote database system, and upon a match establishing a communication channel between the preceding vehicle and the host vehicle, identifying to an operator of the host vehicle preceding vehicles with which the communication channel has been established, and obtaining from the operator a selection of a target vehicles to engage following of. Finally, autonomous following mode of the target vehicle is engaged, wherein a vehicle control system automatically controls at least the following three main functions of the host vehicle: forward propulsion, steering, and braking.

The invention discloses an intelligent weeding robot system based on depth vision, and belongs to the technical field of intelligent robots. The system includes an industrial personal computer, a power module, a dolly body, a crawler wheel, a hydraulic claw and weeding equipment. The crawler wheel driven by a driving wheel drive device is installed on the dolly body. The hydraulic claw and the weeding equipment are installed on the dolly body through a weeding mechanical arm device used for adjusting the postures of the hydraulic claw and the weeding equipment. The driving wheel drive device,the hydraulic claw and the weeding equipment are all powered by the power module and controlled by the industrial personal computer. The system further includes a depth camera module for measuring therelative position relationship of weeds, crops and the dolly body. The system has the advantages that the interaction function of two mechanical arms can be achieved by the interactive work of a single mechanical arm, and meanwhile a precise weeding method is adopted and can effectively reduce the secondary damage to crops and greatly promote the application and development of intelligent weedingrobots on the premise of ensuring the weeding efficiency and accuracy.

The invention provides an auto-driving vehicle testing method, device and system. The method comprises: performing obstacle labeling on each of the acquired perceptual data to obtain a corresponding standard obstacle labeling result; acquiring obstacle labeling results generated by using an environment sensing system to perform obstacle labeling on the perceptual data; determining that the environmental sensing system is normal when each obstacle labeling result is identical to the corresponding standard obstacle labeling result; transmitting at least one virtual environment data to a vehiclecontrol system of an auto-driving vehicle after it is determined that the environmental sensing system is normal so as to allow the vehicle control system to control the auto-driving vehicle to travelon a test field without obstacles according to the virtual environment data; acquiring travelling condition data of the auto-driving vehicle traveling on the test field; and determining that the vehicle control system is normal when each traveling condition data matches the corresponding virtual environment data. The solution can reduce the cost of auto-driving vehicle testing.

A mooring arrangement between a floating storage body spread moored in deep water and a shuttle tanker, the arrangement including a single point buoyant member that is adapted for mooring a shuttle tanker in offloading position relative to a floating production, storage and offloading vessel (FPSO) with a link between the floating storage body and the single point buoyant member. One embodiment (100) of the invention employs a submerged yoke (30), having one end (31) rotatably coupled to a FPSO (10) and a second end (32), supported by a buoy. A mooring hawser (28) extends from the buoy to the shuttle tanker and product hoses connect the shuttle tanker with the FPSO and extend along the submerged yoke. In another embodiment, the mooring buoy is stationed by a hold-back mooring system (303-304) and the FPSO or the tanker or both is provided with traction devices (308) to move the tanker into loading position with respect to the FPSO. Other embodiments of the invention establish mooring of a shuttle tanker so that it can weathervane 360 degrees during offloading activity. In another embodiment, the mooring buoy (600) is provided with a dynamic positioning system (614) for controlling shuttle tanker positioning with respect to conditions of the environment or for moving the tanker to a desired position during loading.
