Abstract


In this paper, a design of 2 wheel drive (2WD) mobile robot that is controlled by using speech recognition is proposed. The mobile robot operates with a speech recognition module that can interpret a set of commands spoken by human. Based on the command received, the mobile robot makes a certain movement in its environment, as it is guided from a starting point to a destination point. Besides, the mobile robot is equipped with one ultrasonic sensor and two infrared sensors, so that it can avoid collision with objects in the surroundings. The constructed mobile robot fulfils the design objective successfully. The mobile robot is able to be triggered and to comprehend a set of commands. Thereafter, the commands are translated into rotation of the two in-wheel motors, so that the mobile robot can move forward, turn left, turn right, move backward, and stop. The mobile robot will stop moving forward if the sensors detect any obstacles, and it is to be directed to get around the obstacles. The mobile robot is effectual to carry objects with weight of 400 grams. The mobile robot is reckoned to be a model for next generation robots that assist human to transport objects in domestic and industrial activities.
