Subsystem Build & Test
Table of Contents
Team Vision for Subsystem Level Build & Test Phase
The team planned to get quotes from outside vendors for particular components of the device design, update the BOM and budget to make a request for more money, and put finishing touches on the CAD model. The team also planned to start the welding and subsystem building process.
The team finished making the CAD model of the device and sent it out to vendors to acquire quotes. The team consulted with a welding expert and created a plan of how and where welding would occur in the assembly of the device. Components for the subsystems of the device were ordered. The budget was updated to include the quotes from suppliers to create a proposal for a budget increase.
The team also started preparing outlines for the final paper and poster to properly document the process the team has gone through. Imagine RIT space was requested in our official presentation proposal.

Final CAD Model
The model of the device was finalized and sent off to vendors to get quotes on how costly certain manufactured parts may be.
Risk and Problem Tracking
The Risk Assessment was updated to decrease risk ratings that have been mitigated or prevention put into place, and any new risks were added to the list. The full document can be found here.
Risks that were lowered in Importance:
- Running out of money - requesting budget increase with new quote information from suppliers
- Inaccessible water source during Imagine RIT - requested specific location with water source available
- Guide rod misalignment - using one piece base plate
- Can't machine large steel plates on RIT machinery - ordering from outside supplier
- Aluminum frame may be subject to bending - using steel instead
- Team has little to no experience welding - working with welding expert
- Water leaking in cylinder - the first build passed testing
Risks with high importance that the team is monitoring closely:
- Pipes interfering with wheelchair motion
- Hand could slip off handle
- Second hydraulic cylinder build fails testing
- Design requires a 3 way valve with 3 different capabilities
The Problem Tracking spreadsheet was updated to include new problems the team is facing. The full document can be found here

The next steps for the team will be to request a budget increase, order the tubing and seat place, design the lever and valve system once the test valve arrives, build the second hydraulic cylinder, and complete welding activities.
