Project Requirements
IntroductionAbstract
• Indoor or outdoor (under favorable weather conditions)• 14 – 33 degrees Celsius• No drop-offs or stairs• Environmental obstacles must be at least 2.5 feet high
Operating Environment
Users• Ongo-01 team members• Visitors to ISU campus• ISU faculty and staff
Uses• Demonstrating 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• Enough power is available to run all components
Limitations• Fits through a 30-inch doorway• Systems housed on chassis• Power supply is finite and must be recharged periodically
Assumptions and Limitations
• Wireless control through a graphical user interface (GUI)• Manipulate objects up to five pounds in weight• Self-correcting navigation and obstacle avoidance• Technical documentation and schematics• Components of the end product as shown in Figure 1: End Product Layout
Expected End Product
General Problem StatementTo capture the interests of visitors and potential students, the College of Engineering needs an exciting demonstration of the technological capabilities of its students.
Problem Statement
General Solution – Approach StatementBy integrating diverse disciplines to create an autonomous robot, OSCAR will embody the full range of technical skills studied at Iowa State University.
OSCAR is an autonomous speech controlled robot created to spur the imagination and enhance the interest of students in the engineering programs. Combining power delivery, computer software, a sonar array, motors, and a mechanical arm, OSCAR provides the platform to demonstrate the extent of the engineering capabilities at Iowa State University. By the end of this semester, the College of Engineering will have a demonstrable robot that can be shown to the community with pride.OSCAR can be used to demonstrate the individual technical skills and inter-disciplinary coordination that come from an ISU education, while also providing a tactile, interactive, robotic ambassador for the University.
Design Objectives• Operational end effector arm• Improved belt drive performance• Wireless control through GUI• Attractive and functional exterior
Functional Requirements
• 192 MB PC RAM, 233 MHz CPU• 100 ft. wireless range• 12” radial enclosure• 120° of end effector rotation
Design Constraints• Fix existing drive train• Design and implement new end effector• Develop GUI for end users• Develop and implement navigation algorithm
Measurable Milestones
• Navigation on smooth surfaces• Recognition and avoidance of obstacles• Placement and retrieval of objects• Speech output
