Team Vision for Integrated System Build & Test Phase & Imagine RIT

Teams plan for integrated system build and test

• Assemble rails

• Test flow of rails at multiple angles

• Attach rails to frame

• 3-D print and assemble sorter

• Design changes for sorter based

• Attach sorter to frame

• Test tip blockage in storage in full assembly

• Test for flow distribution throughout the machine

• Test full system (fill a tip box)

• Collaboration on final redesign of parts

• Edge uploading of documentation

What did the team not accomplish during the phase?

• Collaboration on final redesign of parts

• Test full system (fill a tip box)

• Complete testing for flow distribution throughout the machine



Imagine RIT Status

Exhibit is confirmed but no location has been assigned yet.

What does the team want to accomplish for Imagine RIT?

All subsystems work together, a full bag of tips (~1000 tips) flowing down the storage through the sorter down the rails without any damage to the tips with a 90% success rate. The machine should be able to stop when the rails are lifted from the filling position to the loading position. at-least a box should be able to be filled in front of audience. All questions can be answered by any group member regarding operation, maintenance, storage etc. A final poster showing the progress of the project, all the way from initial design to the final working. Future concepts of using a motor for storage ramp tilting improving deign functionality will also be discussed.

Test Results Summary

First Integrated System Test

First Integrated System Test

After Our first full system test in our mid phase demo we noticed several glaring problems. The most problematic being that we had no way to control the flow of the tips. We recognized this could be a problem and tried to account for it in other areas. However our solutions barely had any affect on the root cause. The changes we plan to make to address this and the other problems are in the "Rework for final Hand-off" section below.

Problem Troubleshooting 1 Fixing The Box Together

From last phase the holes associated with fixing the box together were placed in wrong places, Since lazercut machine was not working, the new holes were carefully hand drilled.

Problem Troubleshooting 2 Making The First Ramp Movable

In order to order to accomplish that the following steps were followed.

  1. Remove the notches from the ramp sides


  1. Mount Two hinges on the ramp and the side sheet to allow it to rotate
  2. Glue weight below the ramp to make it fall down
  3. Mount the motor at a decent position to allow it to move the ramp
  4. 3-D print an oval shape and mount it to motor shaft
  5. Lazercut a square hole in the side sheet to insert motor shaft from

Device Weight

The current Weight of the device is at 43 lbs. We plan to extend the device several inches while reducing its height, we expect these to cancel out any change in the weight.

Live Risk Management

This phase didn't add any new risks to our project, we resolved a lot of the risks that came up earlier. We have new problems with the design which are later discussed in the problem tracking. Some of the risks we have resolved are like the pipettes falling out of the holder for which we remade the lanes with a metal block which holds the tolerance much tighter than the wooden block. We made sure all salvaged parts are washed and cleaned for debris and oil. A critical risk of tips not being able to fill in to the tip box was resolved by using a filler support which has long stems on it which help hold the tips in the lanes line up with the tip box.

Problem Tracking

Our updated Problem Tracking reflects all the problems we have seen up to and including our mid phase demo.

Rework For Final Hand-off






Future Phase Plan & Individual Plans

Below is what our next phase looks like.
Phase plan for Customer Handoff & Final Project Documentation

Phase plan for Customer Handoff & Final Project Documentation

All Building and testing on parts will be lead by the engingeer responsible for it (Storage: Abdallah, Sorter: Andrew, Rails: Linga). The testing on the assembly will be done as a team.

Individual 3 week plan of the team including what has been done, what needs to be done and what the individual has learnt for each phase.
