/public/

Planning

Table of Contents

Product Description/Objective Statement

To reduce the cost of existing motor modules through redesign and cost analysis so that multiple modules may be produced and used by the KGCOE.

Key Project Deliverables

Key deliverables for this project include a robust, low cost motor module that can easily integrate with both the Land Vehicle Platform as well as the Motor Controller.

Primary Project Opportunities

Primary opportunities for this project include educational applications for first year students, a wide range of faculty and graduate research projects, and sales of kits to the public at large. This project also provides the opportunity to showcase the engineering talents of RIT students to companies interested in hiring them.

Assumptions and Constraints

It is assumed that this will be a wheeled vehicle that can traverse a variety of terrains and be assembled from modules to form a variety of configurations.

Stakeholders

Stakeholders for this project include the Kate Gleason College of Engineering at RIT, faculty and graduate researchers, current and future senior design teams, students interested in the multi-disciplinary robotics club or FIRST robotics, and the student body as a whole.

Customer Constraints

The base level constraints placed on the project by the customer, as defined by the project family track can be found here.

Preliminary Customer Needs

Motor Module Manufacturability
  • Perform at or above the level of the previous module.
  • Must look professional and well-organized.
  • Reduce the overall unit cost from the previous module.
  • Must be lighter than the previous generation.
  • Must be faster than the previous generation.
  • Must be easily manufacturable in lots of 1-10 units.
  • Must be easy for a first year engineering student to assemble and use.
  • Must be open source (all documentation published).
  • Must be open architecture (COTS parts used).

Risk Assessment

Description of Risk Possible Consequences Probability of Risk (H/M/L) Severity of Risk (H/M/L) Overall Risk (H/M/L) Contingency Plan
Team member missing for extended period of time Components may be missing from final project M M M Delegate times to meet and update all members on status of specific areas of research, good documentation
Parts/Materials Arrive Late Delayed assembly and testing period, possibly miss deadline for completion H M M Design module so process does not hinge on ordered parts. Cite multiple vendors for same components
Module causes decreased performance of land vehicle Speed, Stability and/or Weight do not meet customer requirements L H M Weigh customer requirements highly during design process
New module costs the same as previous generation Too few modules are produced to meet project specs M H M Pitch project family idea to investor with more capital
New module fails to integrate with concurrent and past projects No working vehicles can be produced L H M Hold regular meetings with concurrent teams to ensure integration, and base all designs off of older components
