Project Background and Approach

Project Background

Over the past four years, RIT students have designed, assembled, and tested the Wandering Ambassador. They have succeeded in their goal of showcasing the creativity and aptitude of RIT students. Since the first year, the complexity of the project has grown immensely. The task of comprehending and understanding past modifications to enhance the project further has become a laborious task. Any further multidisciplinary modifications can only be done in a serial progression because of the current layout causing unnecessary time delays.

Project Statement

Our goal is to reduce the period in which a new group can familiarize themselves with the Wandering Ambassador. In addition, a comprehensive testing platform will be designed to allow quicker problem solving and multidisciplinary work to be performed in parallel.

Objectives/Scope:

Improve modularity of the system to be able to separate and reassemble the electrical and mechanical components rapidly. Keep the electrical system organized and optimized for future improvements. Enhance the campus experience for prospective students. Showcase aptitude of RIT engineering students Create a user friendly interface for detecting hardware malfunctions. Tutorials for I2C interfaces and data analyzer.

Deliverables:

Expected Project Benefits At present, prospective RIT students interact with human ambassadors who guide them around the campus. This project will help these students discover the possibilities an RIT education can provide. Students will be able to interact with The Wandering Ambassador to find directions, local weather, events, dining locations and other information pertaining to campus life. In addition, the proposed improvements and learning tools will help future engineering teams further develop the Wandering Ambassador platform.

Strategy & Approach

Assumptions & Constraints: The team must have a well-rounded understanding of the current Wandering Ambassador robot in order to enable off-line development, experimentation, and debugging. The team must assume particular components of the current robot are operable. The ability to enable parallel development and create a modular system for upcoming teams will prove to be a constraint due to several technologies being developed simultaneously. The team will focus on design issues throughout the duration of the project in order to assist the development of future design iterations.

Issues & Risks:' Increase reliability of Wandering Ambassador

Redesign of selected systems to allow for increased functionality and addition of peripherals by future MSD teams

Mitigate troubleshooting by creating a test stand, disconnect system and diagnostic GUI
