System and method for tracking obstacles by an autonomous vehicle. Localization sensors (i.e., sensors to measure pitch, roll, and yaw, and systems including an inertial navigation system, a compass, a global positioning system, or an odometer) detect the position of the vehicle. Perception sensors (e.g., LIDAR, stereo vision, infrared vision, radar, or sonar) assess the environment about the vehicle. Using these sensors, locations of terrain features relative to the vehicle are computed and kept up-to-date. The vehicle trajectory is adjusted to avoid terrain features that are obstacles in the path of the vehicle.

The 3D additive repair device for laser-arc hybrid welding and the repair method have the beneficial effects that the structure is simple, operation is convenient, and reliability and adaptability are high.

The laser targeting system of the present invention eliminates the problem of parallax between the arrow's path and the archer's line of sight. An embodiment is a laser integrated into an arrow such that the beam is projected down the axis of the arrow. Another embodiment is an arrow rest with an integrated laser, which can have an angular adjustment. By having the laser extend the axis of the arrow to the target, the laser spot produced on the target accurately represents where the arrow will hit once released, and eliminates the parallax angle between the archer's line of sight and the arrow's path. The present invention also provides a means for using a single laser beam to project a diffractive pattern onto a target, such as several spots or crosshairs. For advanced visibility of the laser spot, an optical filter or infrared vision optical sensors can be used.
