Team Vision for Integrated System Build & Test Phase
The goal for this phase was to integrate the working components that we completed in our last phase into a working system. The expectation for the end of this phase is to have an assembled car that moves forward based on input from the remote control. Ideally, all of the child controls would be active and working.Subsystems to be integrated
-
Electrical
- Connect batteries to components so that car can
run autonomously
- motor
- motor controls
- joy stick
- Raspberry Pi
- Connect batteries to components so that car can
run autonomously
-
Mechanical

- Car seat mount
- Child control tray
- Child control tray movement enablers
- Joy stick mount
- Wii wheel mount

Test Results Summary

Proof of Forward Motion
One major concern that was that the motors provided in the original car would not be powerful enough to move the car with the added weight of the carseat and wooden base. A video proving that this motion is possible can be found using this link: https://youtu.be/TYfI1oSOGXcProof of Speed Levels
This video demonstrates that depending on the amount of pressure on the playstation joystick. This speed is easily configurable in software so the team will choose an appropriate max speed for this purpose. The video can be found using this link: https://youtu.be/iPcTINK4w00Proof of Remote Controlled Steering
A video of our power steering system can be found here:https://youtu.be/iNWKU9u2VHE A second video of our power steering can be found here:https://youtu.be/upWpB6FOnA4Other tests
To date the team has completed the following tests to ensure that safety and functionality of our vehicle.- RC Range
- RC Field
- Seatbelt adjustability
- Torque to turn wheels
- Seat Fitment
- Remote controls available
- Carseat mounting strength
Risk and Problem Tracking

Plans for next phase
Gantt Chart
A link to our up to date Gantt Chart can be found here.Final Plans
- We will be meeting with our customer on 11/9 to present the progress that we have made on the car.
- The final phase of this project will be to finish any small tests or repairs to the system to make sure that it functions optimally. We also will spend the remaining time completing our technical paper, polishing our edge page, and writing up a user manual for the vehicle.
Team level goal for next phase
Electrical team goals:
- To connect the pi upon receiving usb converter
- To clean up wiring (have it contained in housing and hidden)
- To have the full program running all working subprograms
Mechanical team goals:
- To have child tray fully assembled and able to move
- To build wii wheel mount
- Clean up final appearances of exterior
Alaiya’s plans and prior goals:
Outcomes of the prior phase
- In the prior phase I planned to finish all wiring of the vehicle so that it was ready to test autonomously.
- One main part for wiring did not arrive during this phase, however we wired as much as possible and found ways to test the car. The only thing that was not connected was the pi, which we are temporarily running from a laptop. This also allows us to test and change the code more easily.
- I learned that sometimes parts don’t show up and to make due with what we can to continue progress on the project.
Plans for Next Phase
- Work on instruction manual
- Supporting Feasibility Analysis part of paper
- Clean up wiring (with Allison)
- Ensure all wires and moving parts are not accessible to the child
Allison’s plans and prior goals:
Outcomes of the prior phase
- In the prior phase I planned to finish all wiring of the vehicle so that it was ready to test autonomously. And coordinate tasks for team members to remain as close to the planned timeline as possible.
- The system was not fully integrated, because some parts did not arrive and the teams were unable to fully coordinate efforts.
- I learned that ordering parts as soon as possible is vital.
Plans for Next Phase
- Overhaul Edge page
- Description of the power steering system part of paper
- Clean up wiring (with Alaiya)
- Ensure all wires and moving parts are not accessible to the child
Austin’s plans and prior goals:
Outcomes of the prior phase
- In the prior phase I planned to debug the code.
- The car was not assembled as soon as planned for testing. The debugging process is never fully complete.
- I learned more about how python operates.
Plans for Next Phase
- Description of software part of paper
- Continue to debug code
- Write documentation of the code
Brady’s Plans and Prior Goals:
Outcomes of prior phase
- In the prior phase I planned to update the BoM, mount the child control tray with joystick and wheel.
- Once we had the joystick and Wii wheel we realized they wouldn’t both fit on one tray so we built a second to tray so each control system has its own tray.
- I learned it is important to confirm to communicate what has been ordered very clearly.
Plans for Next Phase
- Complete BoM with visuals
- Make a permanent mount for Wii wheel(with Solomiya and Kathryn)
- Clean up any, rough or sharp edges, fix any safety issues on car.
- Results and conclusion of paper
Kathryn’s Plans and Prior Goals:
Outcomes of prior phase
- In the prior phase I planned to write the background of the paper and to aid the mechanical team in assembling the car
- I have also continued to communicate with our customers so that their needs can be adequately met.
- I learned that it takes longer than it seems to assemble the car so that it is ready for testing.
Plans for Next Phase
- Continue to communicate with customers
- Make a permanent mount for Wii wheel(with Brady and Solomiya)
- Help team make any changes to the design realized after the 11/9/18 customer meeting
- Edit the background portion to the tech paper
Solomiya’s Plans and Prior Goals:
Outcomes of prior phase
- In the prior phase I planned to finish child controls and car seat mounting.
- In the process of putting the mounting pieces together, we realized we were missing several key design choices. As a result, many decisions were made on the spot or after trying several options.
- I learned to think through design plans in terms of manufacturing requirements. This includes the initial steps of purchasing and the last steps of screwing pieces together.
Plans for Next Phase
- Create poster
- Finalize Wii wheel mounting and joystick arm support
- Update car per new customer requirements after customer meeting and testing
