To function, OSCAR requires development of multiple technologies, including motor control, electromechanical sensors, power systems, speech recognition, and automatic navigation. The importance of this project will not decrease once the end product is fully developed. To continue developing the interest of visitors to ISU, new technologies added to the Electrical and Computer Engineering curriculum will be incorporated into OSCAR’s capabilities by future teams. Introduction OSCAR is an ongoing project designed to demonstrate the implementation of multiple technologies of electrical and computer engineering in a robotics activity. Design of a robot requires knowledge of software systems, motor controls, power flow, and sensory inputs. It can be used in public demonstrations to showcase the multiple benefits of an ISU education Abstract General Problem Statement Since it will be used by lay persons, the robot must be fully interactive through voice command. The functions performed must meet users’ expectations of current technology. General Solution – Approach Statement Current technologies will be researched and implemented with consideration for limited power and space availability. Problem Statement Indoor/Outdoor 14 – 33 degrees Celsius No rain or heavy wind Smooth terrain Environmental obstacles are at least 2.5 feet high Operating Environment Users Ongo-01 team members Visitors to ISU campus ISU faculty and staff Uses Demonstration of technologies studied in computer and electrical engineering Assisting in guided tours of Coover hall Intended Users and Uses Assumptions Operators speak and read English Trained personnel are present during operation Limitations Fit through a 30-inch doorway All systems housed on chassis Rechargeable power supply Assumptions and Limitations Manipulate objects up to two pounds in weight Navigation and mapping of immediate area Speech recognition and response Self-contained, rechargeable power supply Expected End Product Understanding of environment Interactive speech capability Self-navigating Manipulation of nearby objects Design Objectives Speech recognition and generation Measure position, temperature, and direction Recognize and avoid obstacles Retrieve and place objects Functional Requirements Component space on chassis Available power Heat dissipation Design Constraints Purchase components and materials Implement sensors and motion controls Develop working navigation algorithms Employ speech recognition Demonstrate capabilities to lay audience Measurable Milestones Project Requirements
