Statement of Purpose

Our goal is to create a remote-controlled electric skateboard by attaching a motor and belt-drive system to a traditional longboard. We all were interested in this idea because it’s simply just a hassle to walk everywhere around campus, and waiting for the bus can sometimes be stressful due to somewhat unpredictable departure and arrival times. Plus, it’s so much cooler to skate around campus compared to any other form of transportation. 

We’re setting out to make an electric board from the raw parts because the upfront price for an electric board is quite steep, and also we are planning to customize the board we make. We have a handful of goals for this project:

  1. Create a functioning remote-controlled electric skateboard.

  2. Add voice recognition functionality via an attached microphone.

  3. Possibly add a light sensor to slow the board down in the case of an oncoming collision

Background Research

We decided to work on a boosted board because we wanted to build a method of getting across campus quickly while learning about circuits, sensors, and motors at the same time. What drives us is the eagerness to learn and get hands-on experience with our own project that we have full control over. Last semester, there was another group that made a boosted board, but they attempted to use  a mind-controlling aspect with it. To put our own spin on our boosted board, we have decided to implement a crash-detection sensor as well as voice-recognition software to control the board.  We have watched videos on youtube that thoroughly go over all the parts and steps to build our own board. We have also done some research into the crash detection sensors, and one of our group members has worked with voice recognition in the past. 

Block Diagram / Flow Chart


System Overview

In the first block diagram, it shows a general overview of how the system and parts will be connected to each other. It shows all the inputs we will have: charger, ON/OFF button, and controller. It also shows the outputs we will have for our system: a charge indicator and an ON/OFF indicator.

The second block diagram shows the crash detection system. It shows which connections need to be made between the sensor and the arduino.  

Parts

Provide a list of parts that you may need for your project. You should include details such as the quantity, model number, purpose, vendor, and price (excluding taxes and shipping) for each part. This list may change as you work on your project. 

Board - $10 (buy separately)

Wheels - $35 

Motor - $60

ESC (Electronic Speed Controller) - $10

Raspberry Pi / arduino - $10 (already have)

Microphone - $20

Remote - $25 

Pulley System to connect Motor to Wheels - $30

Ultrasonic distance sensor - $8 (already have)

LiPo Batteries - $10 to $20 each

Possible Challenges

Some possible challenges that could arise with this project could be due to our inexperience. Problems during the design process and implementation could come up. We are all fairly new to working with hardware and software. We will also have to choose between maximizing speed or time by putting our batteries either in series or parallel with each other.

References

List all references you used in your proposal. This is important, you do not want to be blamed for plagiarism. IEEE citation format is highly recommended. You can use citethisforme.com's IEEE citation generator to painlessly generate your references in this style.

Comments:

Hey guys, as a CA I have to preface the project by asking you guys not to test the voice control with humans on the board if the motion is being voice controlled. If you guys "unofficially" decide to test it like that then make sure you are being extra safe. I think you can make a lot of cool voice controls for lighting pretty safely but it's certainly not as satisfying as voice controlling the motion. 

I tell this to a lot of groups but try to break up the project into sensible "chunks" so that if you don't finish the full project you can still have some functionality and stuff to present on. 

If you guys are worried about your inexperience then I really recommend spending a lot of time thoroughly researching the exact parts you need. Especially since motors and batteries are expensive. This will reduce headache later. 


I'll approve your guys project! Start looking for those parts ASAP!
