Redesigning the Hero-1 Robot Group Members: Fernando Delgado |

The Hero 1 Robot was developed in the early 1980s as an educational robot. Our goal for this project is to redesign it to perform a task of following a person. The robot will have one or two basic stamp modules to control its movements. Its movements are driven by a DC motor for forward and backward motion and by a stepper motor for steering the direction of travel. The robot will be triggered to move by an incoming infrared signal from an oscillator carried by the person. The transmitter will be built using a 555 timer and configured to output a desired frequency. The infrared receiver will search for the desired frequency from the transmitter and send a signal to the microprocessor to execute specific tasks. Sonar sensing devices will be implemented to avoid colliding with the walls. To control the velocity of the robot we will be using Pulse Width Modulation, which is controlled by the basic stamp. A 12 volt motorcycle battery is needed to power our robot. The flowchart diagram shown in Figure 1 describes part of the control scheme of the robot. The physical appearance of the redesigned robot will stay the same as it was, but it will be driven by different electronic configurations. At the conclusion of this project, the robot will stay within the ECE Department for future students to take on further modifications. |
