  • Patent number: 7742841
    Abstract: In an autonomous vehicle, position of a planar obstacle such as a wall or a fence having apertures is determined. A horizontal plane is scanned with a laser range tinder so as to acquire positional coordinates of a plurality of scanning points. An element vector is formed with each two scanning points so that one acquired former is used as a start point and the other acquired later as an end point of the vector. A plurality of continuous element vectors which satisfy predetermined conditions is selected among the element vectors, and a scanning segment vector is formed by composition of the selected element vectors. When a length of the scanning segment vector is equal to or longer than a predetermined length, it is possible to recognize that a planar obstacle exists along the scanning segment vector.

  • Patent number: 7739021
    Abstract: A vehicle transmission retarder control apparatus is provided including an engine, a throttle, a brake, a transmission having an output member with an actual transmission output speed, a speed sensor operable for measuring the actual transmission output speed, a plurality of user-commandable input devices for selecting a desired transmission output speed, and a controller having an algorithm for controlling the amount of retarder request to provide a zero or constant rate of deceleration independently of weight and axle ratio. Additionally, a method is provided for controlling a transmission retarder, including measuring the actual transmission output speed, sensing a desired transmission output speed using a plurality of user-commandable input devices, communicating the actual and desired speeds to a controller, and commanding the retarder to apply a continuously variable opposing torque to the transmission based on the actual and desired output speeds to achieve a constant rate of deceleration.

  • Patent number: 7734377
    Abstract: A gait generator determines a desired motional trajectory and a desired object reaction force trajectory of an object 120 for a predetermined period after the current time by using an object dynamic model while supplying, to the object dynamic model, a model manipulated variable (estimated disturbance force) for bringing a behavior of the object 120 on the object dynamic model close to an actual behavior, and provisionally generates a gait of a robot 1 for a predetermined period by using the aforesaid determined trajectories. Based on the gait and an object desired motion trajectory, a geometric restrictive condition, such as interference between the robot 1 and the object 120, is checked, and a moving plan for the object 120 or a gait parameter (predicted landing position/posture or the like) of the robot 1 is corrected as appropriate according to a result of the check, so as to generate a gait of the robot 1.

  • Patent number: 7689320
    Abstract: A robotic surgical system has a robot arm holding an instrument for performing a surgical procedure, and a control system for controlling movement of the arm and its instrument according to user manipulation of a master manipulator. The control system includes a filter in its forward path to attenuate master input commands that may cause instrument tip vibrations, and an inverse filter in a feedback path to the master manipulator configured so as to compensate for delay introduced by the forward path filter. To enhance control, master command and slave joint observers are also inserted in the control system to estimate slave joint position, velocity and acceleration commands using received slave joint position commands and torque feedbacks, and estimate actual slave joint positions, velocities and accelerations using sensed slave joint positions and commanded slave joint motor torques.

  • Patent number: 7684927
    Abstract: A system and method for performing distributed sequential node localization in active sensor deployment is presented. An equilateral orthogonal reference frame is defined. The reference frame includes s+1 anchor nodes that is placed in s-dimensional physical space. New nodes are sequentially placed in a natural sequential ordering within the s-dimensional physical space to form a sequentially well-connected network. For each of the new nodes, location estimates are obtained for the new node from at least s+1 of the anchor nodes previously placed in the s-dimensional physical space. A location is determined for the new node based on the location estimates. The new node are placed in the s-dimensional physical space as a new anchor node proximate to at least one of the s+1 previously-placed anchor nodes upon satisfactory location determination.
