Introduction
Project Description:
As scooters become more and more popular within cities, safety has become more of a concern to the general public. Public safety is affected by the scooter population increasing. Rider safety is a high priority for many different groups. We divided these groups up into what we call our stakeholders. The stakeholders that have the most value in a safe scooter are the Police,the manufacturing companies, and the riders. Each of these groups would benefit from a safer scooter.
Recent studies have shown that at least 8 people have died while using an e-scooter. A research team working with the CDC (Centers for Disease Control and Prevention) found that 20 people get hurt for every 100,000 scooter trips taken. Also, almost half of all the injuries were head injuries. 15% even experienced a traumatic brain injury. This is a huge problem that could have been avoided by the wearing of helmets.
The overview of the problem is designing a safer scooter such that it will fulfill the requirement of protecting the riders. Keep the sense of adventure that riders want while taking into account the needs and wants of the manufacturing companies and law enforcement
Design Methodology, Constraints, Specifications, and System
Requirements (CLO 1):
Our design from Senior Design 1 started as a smart helmet that uses a 360
degree camera, heads up display that can show navigation, and vibrating handlebars that can communicate wirelessly with the camera. However as the design process went on, we decided to limit and change a couple of features. Features that were simplified were having the camera only face the back of the helmet, the HUD shows the speed thanks to the navigation chip, and the vibrating handlebars can’t communicate with the camera wirelessly.
We decided to limit and change some of the features because of the cost and time to implement the ideas onto the helmet. Wirelessly communication was due to the tough coding for sending and retrieving data through the Arduino and Jetson nano.
Engineering Documents (CLO 3):
For our design, our block schematic consists of a voltage source connecting to the voltage regulator that connects to both the jetson nano and arduino mega. The Jetson nano computes the camera and image processing information while the Arduino mega processes the head up display information and most specifically speed calculation. The Arduino nano controls the vibrating handlebars.
Computer Design Tools (CLO 4):
A couple of software we used were python for the arduino coding.
This code is for the heads up display.
This code is for the vibrating handlebars.
For the Jetson nano, it worked similarly to a raspberry pi as the operating system was linux and we used online sources on how to operate the camera. We also used and designed cases from the boards through a 3d printer.
Patent and Standards Research Related to Design (CLO 6):
The smart helmet has never been an original idea as there are many companies out there who are trying to create a smart helmet appreciated by riders. From our research we found many different types of smart helmet but two most noticeable ones were the Jarvish X brand and CrossHelmet X1.
Jarvish X consists of a more advanced version of ideas with added ai voice commands and military grade power lithium battery.
CrossHelmet X1 also consist of similar features by the Jarvish and ours. Both smart helmets solely focus on safety and user likeability when it came to designing their helmets. Like ours, their goal was to make the smart helmet provide information to the
riders without distracting the riders on the
road.
Proof of Concept (CLO 8):
Our proof of concepts and results are shown in the following images below.
Front of the helmet.
Side of the helmet. As one can see, the helmet has the features that we were able to implement such as the heads up display and camera. The reason why it is bulky is because of the processing boards and power. Their “ideal” location in the helmet if we were able to downsize them would be inside the helmet. The proof of image processing can be found in the following image below
As one can see, we coded so it can recognize different objects like a person and chair.
The percentage shows the computer guess on the so-called object. Image processing
takes a lot of memory usage from the Jetson as shown below.
