ABSTRACT
The main difference between navigation requirements for robot and human is the definite and sizeable difference in perceptual capabilities. A typical robot guidance technique generally consists of following the underground-buried cables or painted lines on the surface onto which a robot is supposed to traverse a path. For inertial navigation very suitable sensing device is a gyroscope. The beacons are fixed at appropriate locations in the environment and the precise locations of which are made known to the robot. Dead Reckoning is a method of estimating the position of a mobile vehicle without astronomical measurements, and is the process of estimating the robot current position based upon a previously estimated position-fix. In the ‘Hill and Sword gripper’, the gripper has sensors/buttons on it, which when pressed activate a screen which obscures, as a function of stress which it undergoes, a ray issued from an LED.
