Mechatronics: Group Project Report ECOR1044: Section A Submitted on: 12/06/2022 2. Table 1: List of initial “best” product ideas chosen
Idea: Ben Khadija Sarah Idea 1: Idea 1: One of the ideas for this project was a cereal dispenser. This device would take a bowl to one of three different cereals and fill the bowl with the desired amount of cereal. After this the bowl would move along the track to the milk station where the user would be prompted with their choice of milk, oat milk or almond milk, regular milk is unfortunately not an option due to the lack of refrigeration. Idea 1: Raspberry pi Internet speed monitor This project is designed to utilize a python script written to interact with a program to monitor your internet connection called speedtest CLI, after it has collected the data it will proceed to save the data and upload it to an appointed google drive. Speedtest CLI works by using speedtest.net which will collect your ping, download speed, and upload speed. Idea 1: Pressure Sensor timer for Skiers The project has two push buttons that start and stop a timer. These pressure sensors are placed at the beginning and end of a cross-country ski trail. Hence, when the skier crosses the first pressure sensor it starts a timer. Then, when the skier passes the pressure sensor at the end of the trail it stops the timer and displaces it on a LCD screen. Idea 2: Redesign of the Roomba vacuum. This new “Roomba” would attempt to contend with the original by performing the same tasks while being less expensive. DNS server: This project utilizes an open source software called BIND to set up a DNS. The DNS will help you find your way around networks online through IP addresses. Idea 2: Snowmobile Trail Trackers The project uses a camera to scan a tag on a snowmobile found throughout the trails. This allows the program to keep track of the location of the snowmobile. The posts that hold the scanner also have LED lights to ensure security on the trails. Idea 3: Toy Jedi robot. This toy would drive around autonomously while playing the Meeting indicator screen This project mainly utilizes software but Idea 3: Pressure sensor shoe rack. The project uses a pressure sensor in
iconic “Duel of Fates” and swinging a LightSaber around. This would be targeted to the Star Wars and Kid demographics. still uses some components like raspberry pi and an LCD screen to flash red when it detects a meeting in your calendar, and flashes green after the time has passed. order to let an individual know if their shoes have been stolen. When there is a loss of pressure it would send a notification to a device which notifies the owner of the shoe. The projects found in table 1 were chosen after much debate. A pros and cons list was used to decide which projects are the “best”. 3. The process that was used to select the best idea/design for each team member was looking at how detailed the idea was. This means the more the thought that went into the design the more likely it was to be chosen. This was not the only metric used, practicality is also very important when choosing a design. The more practical the application the easier it will be to market to future customers. Another factor that played a role in picking the project was the interest of the group in the project. The group leaned to a project that is interesting and unique to create. Table 2: Pros and Cons Group Member Name: Idea: Pros: Cons: Ben Cereal Dispenser - Fun to build and design - Very useful - Health Care implementation for the physically disabled - Gives a very futuristic aesthetic - Time Consuming, lots of components to implement - Cross contamination between cereals and milks, could negatively affect those with certain allergies - Waterproofing some of the components would be complicated

Debug Code 10 Setup 6 Test 3 Commercialize/advertise 6 Grand Total: 52 Internet Speed monitor Defining project scope 2 Scope finalized 1 Gather materials 4 Conduct research 4 Setup 6 Scripting code 8 Test 2 Advertise 5 Grand total: 32 Table 4 demonstrates that project schedules depend on the amount of components and the goal of the project. The group used table 4 to gauge the amount of time each project would take to create. The table is a detailed layout of a regular engineering team timeline, all the work that is put into a project and every step that goes into it. It’s a reflection of the direct relationship between complexity and the time taken to finish a project. 6. a) The criteria that were selected for the trade study are: complexity, commercial use and entertainment. The complexity was a factor that was implemented into the trade study because it will determine how hard the project is to execute and how much time is needed to spend on the project. The commercial use is a criteria that was chosen for the trade study because it is important that the product created has a useful application in society. This is one component that determines the success of the product. Furthermore, entertainment was a characteristic chosen for the trade study because it shows the interest of the team that will be working on the project. In turn, it demonstrates the motivation that team members have for working on the project.
b) Table 5: Weights of the trade study criteria Cost Societal Impact Complexity Commercial Use Entertainment 4 3 2 4 2 The weight for the cost of the project was chosen as a 4 because it plays a big role in the ability to create the project and work on the project. As a result, 4 was the weight chosen for the commercial use since there should be a use for the project. To add, the profit should outweigh the cost and effort spent on the project. Furthermore, a weight of 3 was assigned to the societal impact criteria for the weighted trade since the goal of engineers is to solve problems and help society. It also gives motivation to the team working on the project if the product can help others. A weight of 2 was chosen for the complexity of the project since it has an impact on the project. However the criteria would not deter the group from completely choosing another project. A 2 weight was also chosen for the entertainment of the project since it is good to ensure that the team is motivated to work on the project. However, entertainment would not change the entire project. c) Table 6: Weighted Trade Study Team Member Cost (4) Societa l Impact (3) Complexit y (2) Commercial Use (4) Entertainm ent (2) AVG Score: Ben 1 3 1 3 3 2.2 Khadija 3 2 3 3 2 2.6 Sarah 2 1 2 2 3 2 Table 7: Weighted Trade Study Scores with the Weights calculated Team Member Cost Societa l Impact Complexit y Commercial Use Entertainm ent AVG Score:
Ben 4 9 2 12 6 6.6 Khadija 12 6 6 12 4 8 Sarah 8 3 4 8 6 5.8 The project chosen was Khadija’s since it got the highest score in the weighted trade study. The project scored a 6.6 in the weighted trade study. The project scored high on cost, societal impact and commercial use. Ben’s product scored an 8 in the weighted trade study. It scores high on societal impact, complexity and entertainment. However it scored low on the cost. Sarah’s project got a 5.8 in the weighted trade study. It has the project scored in between all scored for the cost, complexity and entertainment. It scored the least on the societal impact. 7. In conclusion, the project that was chosen is the Internet Speed Monitor because it scored the highest in the weighted trade study. After conducting the project, group members have acquired the skills necessary to conduct a weighted trade study. They have realized the importance of weighted trade studies in their future careers and the advantage of this method. In fact, an important lesson that was learnt after conducting the weighted trade study is the importance of prioritizing projects. The group members realized that not all projects can be created. Often due to a lack of resources and time. Hence, it was discussed that the project demonstrated to engineering students that it is important to have the ability to move on from project ideas in order to focus on a better thought out project. Furthermore it was learnt that having a well developed plan is extremely useful throughout the process of planning and designing the project. For example, it was realized that it is easier to ensure that the project is sitting in the budget range with a detailed idea of the components needed for the project. To add, the team grasped early on in the project that a detailed plan for a project gives confidence to the developers while they are selling their ideas to the other team members. In addition, the team members acquired the knowledge that societal impact is a criteria that had a big effect on the motivation of the team members. As a result, the weight for societal impacts is once of the highest weighted criteria. It was learnt that different people have different priorities and beliefs while choosing a project. Hence, the assignment of criteria and weights for a weighted trade study could cause conflict. The team members also realized that weighted trade studies are useful to choose the best project as a team. However, while conducting the weighted trade study, it is important to be aware of the limitations to the technique. As an example, the weighted trade study can be biased depending on the reasoning behind the criteria and its weights that are chosen by the group. References
