Ethical Guidelines

University of Illinois trained engineers are the best and most highly sought in the world. Our graduates are superbly trained, highly competent, and creative. This, however, is not enough. Our engineers must also be trusted to conduct themselves according to the highest ethical standards. All teams must address ethical considerations in their projects. This requirement has two parts.

First, there is a stringent Code of Ethics published by professional societies, such as IEEE and ACM. The power of these Codes of Ethics is to provide guidance to engineers in decision making and to lend the weight of the collective community of engineers to individuals taking a stand on ethical issues. Thus the Code of Ethics both limits the professional engineer and empowers the professional engineer to stand firm on fundamental ethical bedrock. All teams must read the IEEE code and ACM code and comment on any sections of the code that bear directly on the project.

Second, we expect our students to have personal standards of conduct consistent with the IEEE and ACM Codes of Ethics, but also beyond it. That is, there are areas of ethics not addressed by these Codes that the engineer may consider in taking on projects or jobs or making other professional decisions. These are personal standards and choices. In the context of the class, there are no right or wrong answers here. Our students simply need to demonstrate that they are thinking deeply about their own decisions and the consequences of those decisions. We encourage our students to consider the wider impact of their projects and address any concerns raised by potential uses of the project. Students should ask themselves, "Would I be comfortable having my name widely attached to this project? Do I want to live in a society where this product is available or widely used? Would I be proud of a career dominated by the decision making demonstrated here?" Remember that UIUC engineers have a long history of inventions that really has changed the world.

If the students feel that these Codes of Ethics does not directly bear on their project and that there are no other reasonable concerns, they should not invent issues where there are none. Students will still be expected to be familiar with the IEEE Code of Ethics and ACM Code of Ethics.

Problem:

Students living off campus without a packaging station are affected by stolen packages all the time. As a result of privacy concerns and inconsistent deployment, public cameras in Champaign and around the world cannot always be relied upon. Therefore, it can be very difficult for victims to gather evidence for a police report. Most of the time, the value of stolen items is small and they are usually compensated by the sellers (Amazon and Apple are very understanding). However, not all deliveries are insured and many people are suffering from stolen food deliveries during the COVID-19 crisis. We need a low-cost solution that can protect deliveries from all vendors.

Solution Overview:

Our solution is similar to Amazon Hub Apartment Locker and Luxer One. Like these services, our product will securely enclose the package until the owners claim the contents inside. The owner of the contents can claim it using a phone number or a unique user identification code generated and managed by a cloud service.

The first difference we want to make from these competitors is cost. According to an article, the cost of a single locker is from $6000 - $20000. We want to minimize such costs so that we can replace the traditional mailbox. We talked to a Chinese manufacturer and got a hardware quote of $3000. We can squeeze this cost if we just design our own control module on ESP32 microcontrollers.

The second difference we want to make is modularity. We will have a sensor module, a control module, a power module and any number of storage units for hardware. We want to make standardized storage units that can be stacked into any configuration, and these storage units can be connected to a control module through a communication bus. The control module houses the hardware to open or close all of the individual lockers. A household can purchase a single locker and a control module just for one family while apartment buildings can stack them into the lockers we see at Amazon Hub. I think the hardware connection will be a challenge but it will be very effective at lowering the cost once we can massively manufacture these unit lockers.

Solution Components:

Storage Unit

Basic units that provide a locker feature. Each storage unit will have a cheap microcontroller to work as a slave on the communication bus and control its electronic lock (12V 36W). It has four connectors on top, bottom, left, and right sides for stackable configuration.

Control Unit

Should have the same dimension as one of the storage units so that it could be stacked with them. Houses ESP32 microcontroller to run control logics on all storage units and uses the built-in WiFi to upload data to a cloud server. If sensor units are detected, it should activate more security features accordingly.

Power Unit

Power from the wall or from a backup battery power supply and the associated controls to deliver power to the system. Able to sustain high current in a short time (36W for each electronic lock). It should also have protection against overvoltage and overcurrent.

Sensor Modules

Sensors such as cameras, motion sensors, and gyroscopes will parlay any scandalous activities to the control unit and will be able to capture a photo to report to authorities. Sensors will also have modularity for increased security capabilities.

Cloud Support

Runs a database that keeps user identification information and the security images. Pushes notification to end-users.

Criterion for Success:

Deliverers (Fedex, Amazon, Uber Eats, etc.) are able to open the locker using a touchscreen and a use- provided code to place their package inside. Once the package is inside of the locker, a message will be sent to the locker owner that their delivery has arrived. Locker owners are able to open the locker using a touchscreen interface. Owners are also able to change the passcode at any time for security reasons. The locker must be difficult to break into and offer theft protection after multiple incorrect password attempts.
