Problem Statement General Solution – Approach Statement By 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 This project will demonstrate the coordination of computer, electrical, and mechanical engineering students. OSCAR requires the implementation of several technologies including motor control, sonar array, navigation, software graphical interface, power systems, and a mechanical arm. To continue to develop interest and attract attention to ISU engineering, new technologies are continually incorporated to improve OSCAR’s capabilities in the vanguard of robotics technology.
