the authors developed user recognition system for navigation robot. This system is used to prevent navigation robot mistaking user. It uses ZigBee-3D acceleration sensor and kinect sensor. The ZigBee coordinator which is mounted navigation robot know that user comes near to navigation robot by finding the ZigBee accelerometer tag which is attached a user. This tag has unique ID each other, so t...

The need for accurate and reliable navigation techniques for micro air vehicles plays an important part in enabling autonomous operation. Traditional navigation systems typically rely on periodic GPS updates and provide little benefit when operating indoors or in other similarly shielded environments. Moreover, direct integration of the onboard inertial measurement unit (IMU) data stream often ...

New low-cost commercially available bottom-lock doppler sonars can augment or replace the acoustic timeof-flight navigation systems commonly employed for threedimensional underwater robot vehicle navigation. This paper first reviews conventional techniques for underwater vehicle navigation, and describes a doppler-based navigation system recently developed by the authors. Second, we identify pr...

Virtual characters often need to plan visually convincing paths through a complicated environment. For example, a traveler may need to walk from an airport entrance to a staircase, descend the staircase, walk to a shuttle, ride the shuttle to a destination, ride an elevator back to the ground floor, and finally move on the ground floor again to reach the desired airplane. Most previous research...

Described here is a route navigation method for a mobile robot with an omnidirectional image sensor. The route is memorized by a series of two dimensional Fourier power spectrums of consecutive omnidirectional images at the horizon while the robot moves to the goal position. While the robot is navigating to the goal point, it is controlled by comparing the principal axis of inertia of its curre...

An accelerometer-array attitude-calibration method is proposed here. Being based on the compatibility of rigid-body point accelerations, this method can be applied to determine and account for the accelerometer installation errors with a high degree of accuracy. It is assumed that the number of three-axis accelerometers in the array is redundant in order to help reduce the effect of sensor nois...

Autonomous navigation in cross-country environments presents many new challenges with respect to more traditional, urban environments. The lack of highly structured components in the scene complicates the design of even basic functionalities such as obstacle detection. In addition to the geometric description of the scene, terrain typing is also an important component of the perceptual system. ...

A review is given on the use of neural networks for mobile robots and autonomous vehicles. The paper focuses on neural methods for navigation, making a distinction between sensor-based`reactive' navigation and planned navigation methods.
