Project Title
Spybot
Abstract
The team will develop a RC car driven remotely with an Android smartphone. The RC car will be equipped with a camera to provide real-time visual feedback to the smartphone. The camera will also be mounted on a servo to add the capability to change the camera angle. The SJOne will be used to drive the motor and servo of the car in addition to the camera’s servo. The Android smartphone will communicate with the SJOne using Bluetooth. The Android smartphone will be used to command the SJOne and drive the car and motorized camera. The SJOne will stream visual data to the Android smartphone.

Design & Implementation
The design section can go over your hardware and software design. Organize this section using sub-sections that go over your design and implementation.
Hardware Design
Discuss your hardware design here. Show detailed schematics, and the interface here.
Hardware Interface
In this section, you can describe how your hardware communicates, such as which BUSes used. You can discuss your driver implementation here, such that the Software Design section is isolated to talk about high level workings rather than inner working of your project.
Software Design
Show your software design. For example, if you are designing an MP3 Player, show the tasks that you are using, and what they are doing at a high level. Do not show the details of the code. For example, do not show exact code, but you may show psuedocode and fragments of code. Keep in mind that you are showing DESIGN of your software, not the inner workings of it.
Implementation
This section includes implementation, but again, not the details, just the high level. For example, you can list the steps it takes to communicate over a sensor, or the steps needed to write a page of memory onto SPI Flash. You can include sub-sections for each of your component implementation.
Servo Motor
The servo motor is used as a camera mount for the Raspberry Pi camera. It uses a PWM signal and the percentage of how much the servo should pan or tilt is supplied by the Android application
Testing & Technical Challenges
Describe the challenges of your project. What advise would you give yourself or someone else if your project can be started from scratch again? Make a smooth transition to testing section and described what it took to test your project.
Include sub-sections that list out a problem and solution, such as:
<Bug/issue name>
Discuss the issue and resolution.
Raspberry Pi Camera Ribbon
The ribbon used for the camera to communicate with the RPi is very sensitive. While we were testing out the camera and its settings, the video feed would cut out a lot when the ribbon was disturbed. There were times when the camera would not be detected at all. To remedy this issue, we would gently redo the connection again until the video feed returned.
Connecting to the Pi Zero W
Initially, the group wanted to have the phone to connect to the Raspberry Pi through Wi-Fi. However, when setting up the Pi to be a Wi-Fi host, the phones could not discover the Pi making communication impossible. Furthermore, it did not allow the Pi to initially boot up properly. To rectify this problem, the group decided to have the mobile phone with the application be a hotspot host. While this means that the Pi would have to be reconfigured every time it wants to connect to a new phone, the results would be consistent with the feed from the camera being able to broadcast to the host phone.
