The Robotics and Vision Laboratory is a premier research centre that pursues active research on mobile robots and computer vision. Since its inception in early. September, 1999 it has demonstrated significant progress in the fields of Artificial Intelligence and its application in navigational planning of mobile robots.
Housed in ETCE building at room no. CC-3-20, this laboratory is an extension of the well-known Systems and Information Laboratory (room no. T-5A-6), which has produced many Ph.D. s, and contributed significantly to the disciplines of Artificial Intelligence for more than a decade.
The Robotics and Vision Laboratory is currently equipped with one Nomad Super Scout II mobile robot, procured from Nomadic Technologies, U.S.A., and other accessories to run the robot in a closed environment.
The Nomad Super Scout II robot is a modern educational robot specially built for navigational planning in a constrained environment. The robot contains 16 ultrasonic sensors, one video camera and 32 tactile sensors placed around the robot (Fig. 1). It has three wheels, out of which the front two wheels are controlled by two independent stepper motors, and the back wheel is for mechanical balancing of the structure. The direction of movement: forward / left turn / right turn of the robot is controlled by setting respectively equal / more in right / more in left speeds to its front two wheels.
Housed in a metallic frame, the robot contains one power board that drives the motors, one controller card that senses the video, sonar and tactile signals and generates control commands for the motions of the wheels. The speed of the wheel is also controlled by a pulse width modulator that receives current speed of the motors from encoder discs connected with the wheels. The robot also contains one Pentium mother board, that generates high level control commands for motions and sensing in a Linux environment. The robot can be controlled either from the on-board Linux, or through a remote R.F link with a host computer that generates and transfers the control commands to the Pentium board inside the robot.
