Exploring MECH 423: A Hands-On Journey in Mechatronics

If you’re considering mechatronics in your mechanical engineering journey, MECH 423: Mechatronics Product Design offers a glimpse into the field’s exciting and interdisciplinary nature. It’s a lab-focused course where you apply concepts from various areas to build systems from the ground up. Here’s what to expect and how it shaped my learning experience.

MECH 423 is entirely project based, which makes it one of the most practical, hands-on experiences you can have in your mechatronics degree (alongside Capstone) where you will use your knowledge from controller design (MECH 467), sensors and actuators (MECH 420) and other software courses like (CPSC 259, CPEN 333) to develop a mechatronics product. The course is a marathon of problem-solving and design challenges that push you to learn by doing—and trust me, it’s as rewarding as it sounds.

The journey begins with foundational labs:

Lab 1: Understanding the software architecture of a mechatronic system. Here, you dive into C# programming and learn how to create user interfaces (UI). This forms the basis of how you’ll interact with mechatronic systems.
Lab 2: Embedded system design in embedded C. You’ll explore the intricacies of firmware development, bare-metal programming, and the embedded architecture that forms the backbone of modern mechatronic devices.
Lab 3: A culmination of the first two labs. You solder a PCB, integrate motor drivers, and program the logic for a two-axis gantry system. This involves blending hardware and software skills—everything from controlling motors with firmware to interfacing with a C#-based UI application.

And finally we work on a project of our choice that synthesizes everything. This is where creativity and technical knowledge collide, and you can create something truly interesting and meaningful in a short span of around 1 month.

Our Project: A Robotic Gripper

(You can also read about Janet’s MECH 423 project here.)

For my project, we built a robotic gripper that could adjust its grip force. The idea was simple but important—robots need to handle all kinds of objects light and heavy, long and narrow, short and bulky. The goal was to design a gripper capable of adjusting its grip force to interact safely with objects or even humans. Imagine a robotic arm picking up both a heavy box and a delicate sugar cube—it needs to know how much force to apply to avoid damaging the object.

Load Calibration of the gripper.

Here’s how we approached it:

Gripper Design: We designed a sturdy yet flexible mechanism for gripping objects securely without causing damage.
Force Control: We implemented a current-control system on firmware and calibrated it using a load cell to measure the force. A potentiometer let us manually adjust the grip for different objects.
Electrical Components: We worked with motor drivers and hall sensors to power the system and provide feedback.
User Interface: Using python, we built a simple application to monitor the force being applied.

The design day demo involved putting our finger in between the gripper and demonstrating how a low grip target set on the gripper makes it easy to pick objects like sugar cubes without crushing them and reduce pinch hazard during human – robot interaction and at the same time it can pick up weights as heavy as 20 kgs without hesitation.

Advanced robotics use computer vision, train on input data and finally categorize, detect and recognize objects and set a target force based on the object in front of the gripper. Given the timeframe and the scope of the project, we didn’t go that far but we still managed to build a reliable, functional system we were proud of.

The process wasn’t without its challenges. Debugging became our second nature—almost like a rite of passage. Spending 3–4 hours in the lab every evening (and occasionally battling headaches from stubborn bugs) was tough, but the satisfaction of seeing our system come to life made it all worthwhile.

MECH 423 shows you the practical side of mechatronics: building, testing, and refining systems until they work seamlessly. It’s not always easy, but it’s incredibly rewarding.

Yes, the challenges are real. Expect sleepless nights, endless debugging sessions, and moments of self-doubt. But with every solved bug, every lab success, and every project completed, you’ll find yourself becoming a more confident, capable engineer. This is when you start to think beyond grades and truly appreciate how seamlessly these products have incorporated into our lives and marvel the engineering going behind it.

If you thrive on challenges and crave the satisfaction of creating something from scratch, mechatronics is for you. The degree equips you with a unique skill set that blends mechanical, electrical, and software engineering—preparing you for a future in automation, robotics, IoT, and beyond.

So, prospective students: dive in. Embrace the bugs, the setbacks, and the late nights. Because at the end of it all, you’ll look back and realize it was worth every single moment. And who knows? Maybe one day, you’ll be designing systems that change the world.

Research or Industry: What is the right choice for me?

As graduation approaches, many of us face a big question: Should I pursue a career in research or dive into industry? Both paths offer rewarding experiences, but the right choice depends on your passions, goals, and desired work environment.

Why Choose Research?

If you’re deeply curious and passionate about diving into a specific area, research might be the perfect fit. Academic research allows you to explore uncharted territories, develop new knowledge, and contribute to solving global challenges. In Canada, research roles—especially in universities—are often well-supported through grants, encouraging innovation in various fields, including clean energy, materials science, or advanced robotics.

Advantages of Research:

Deeper Exploration: You can pursue a topic you’re truly passionate about, with the freedom to experiment and innovate.
Academic Environment: Surrounded by experts, you’ll have mentorship opportunities and the chance to collaborate with leading scholars.
Flexible Schedule: While research demands dedication, academic environments often offer more flexibility around work hours.

Challenges of Research:

Deadlines & Funding: Research timelines are tied to funding cycles and grant approvals, which can add pressure. But this also fosters project management and proposal-writing skills.
Long-Term Focus: Research outcomes may take time to materialize, so patience and persistence are key.

Why Choose Industry?

On the other hand, jumping into industry gives you hands-on experience in applying what you’ve learned. Industry roles bring a dynamic pace, where you’ll work on real-world projects and see immediate impact. Canada’s booming sectors—such as renewable energy, automation, and AI-driven technologies—offer diverse opportunities for mechanical engineers.

Advantages of Industry:

Immediate Impact: You’ll apply classroom concepts directly and quickly see the tangible results of your work.
Broader Skill Development: In industry, you’ll gain skills beyond engineering, like project management, teamwork, and communication. Industry also pushes you to solve complex, multi-disciplinary problems, broadening your expertise.
Structure and Deadlines: If you thrive in a fast-paced environment with clear deliverables and timelines, industry will keep you engaged and motivated.

Challenges of Industry:

Tight Deadlines: While exciting, industry roles come with structured deadlines and fast turnarounds. You’ll need to prioritize efficiency and adaptability.
Less Flexibility: The focus is on delivering results, which can mean less freedom to explore side interests compared to academia. But this can be a great way to master time management.

Ultimately, choosing between research and industry comes down to understanding what excites you. If you’re passionate about deep dives into specific topics and don’t mind delayed gratification, research will let you push the boundaries of knowledge (You can read more about undergraduate research opportunities undergraduate-research-in-mech. If you want to apply your skills immediately and see direct results, industry offers an exciting, fast-paced environment to grow in. Alternatively, you could pursue a role in Research and Development (R&D), where you get to experience the best of both worlds. Many companies are at the forefront of developing cutting-edge technologies, combining deep research with practical industry applications. During one of my co-op terms, I had the privilege of working at an R&D company focused on developing the world’s first nuclear fusion reactor (Can read more about my co-ops at my-coop-experience. It was an incredible environment where research directly translated into tangible industry results—a perfect balance of innovation and impact.

Both paths offer incredible opportunities, and the best part is, Canada’s engineering landscape supports both transitions. Ultimately, it’s all about what drives you—so think about what environment energizes you most and makes you happy :))

5 Perfect Long Weekend Escapes in Vancouver: Unwind from Midterms and Recharge for School

As midterms loom on the horizon, it’s easy to get overwhelmed by the mountain of assignments, deadlines, and labs. But hey, before Vancouver turns back into “Raincouver” and we’re buried in our textbooks (or laptops), there’s no harm in hitting pause to soak in the last bits of sunshine! For those of us who aren’t from Vancouver (like I was, once upon a time), there’s so much to explore. Over the past five years, I’ve had the chance to experience the city like a Vancouverite. Here are my top 5 (sober!!) must-dos if you’re looking to unwind this long weekend!

1. Chill at One of Vancouver’s Stunning Beaches

I know, I know, it sounds basic, but how many cities can offer both mountain and ocean views at the same time? Vancouver’s beaches are a magical combination of golden sands, volleyball games, and that calming sea breeze. Whether you hit up Kitsilano Beach for a casual day out or paddleboard at Jericho, the beach is the place to unwind. If you’re lucky, you might even spot an orca playing in the distance. Not a bad way to hit pause before exams, right?

2. Hike the Sea-to-Sky Highway

If you’re a nature lover (or even just someone looking to disconnect from all things tech), there’s no better cure for midterm stress than a hike along the Sea-to-Sky Highway. The drive alone is breathtaking, but the real gems are the trails that wind up into the mountains. Garibaldi Lake, Stawamus Chief, and Joffre Lakes are just a few iconic hikes that will reward you with turquoise-blue lakes, towering waterfalls, and views that feel straight out of a screensaver. Bonus: Being out of Wi-Fi range gives you the perfect excuse to ditch your phone and just breathe.

3. Gastown: Where History Meets Hipster Vibes

Gastown has that old-European charm, with cobblestone streets and architecture that takes you back in time. My personal favorite? The iconic steam clock that whistles every 15 minutes—no matter how many times I see it, it never gets old. And hey, while you’re wandering, grab a coffee at one of the quaint cafes. Just remember, stay away from East Hastings if you’re not looking for any “surprises” (trust me on this one).

4. Feel the Need for Speed: Go Karting

Okay, this one might seem random, but there’s nothing like the thrill of racing around a track at high speeds to clear your head. Whether you’re a speed demon or just someone looking to blow off some steam (pun intended), go-karting is the perfect adrenaline rush. Plus, it’s a solid way to take your mind off the fact that you haven’t started studying for that midterm yet…

5. Explore Nature at Bloedel Conservatory and Stanley Park

If fast cars aren’t your thing, maybe a more tranquil escape is calling your name. Stanley Park and the Bloedel Conservatory offer lush green spaces where you can walk, bike, or just sit and people-watch. Wander through the tropical rainforest under the Bloedel dome or bike along the seawall for a full nature detox. Don’t forget to check out the Aquarium, where you’ll find mesmerizing sea creatures and get a break from reality.

Honorable Mention: Sleep (My Personal Favorite)

If you’re more of a homebody, a long weekend is also the perfect time to catch up on sleep. Waking up without an alarm for even just one day is pure bliss. Throw in a TV binge session (you earned it!) and maybe some snacks, and you’ve got yourself the perfect recharge. Forget your stress, calorie count, assignments, and your upcoming deadlines—just for a little while—and you’ll be ready to tackle the next round of school madness with fresh energy.

So, there you have it—five solid ways to unwind and make the most of a long weekend in Vancouver. Whether you’re an adventurer, a beach lover, or someone who enjoys a quiet day in, there’s always something to help you reset before the academic grind kicks in again. Enjoy it, because before you know it, we’ll be in Raincouver mode! ⛈️

Prioritizing Mental Health During Exam Season

Exam season—two words that instantly bring stress to every student’s mind. For us in mechanical engineering, balancing difficult courses, projects, and the pressure to perform well can be overwhelming. But while studying and acing exams is important, taking care of your mental health during this high-stress period is even more crucial.

For me, de-stressing is key to staying focused and relaxed. Going for a run, playing soccer, or doing a quick workout really helps me clear my mind. Physical activity works wonders when you’re stuck in study mode for hours, and it doesn’t have to be complicated—just get moving. Whether it’s hitting the gym or taking a 15-minute walk around campus, you’ll feel the difference. It gives your brain a break, helps with focus, and resets your energy.

Sleep—Easier Said Than Done, Right?

Getting 8-9 hours of sleep before an exam is what I aim for, but I know that’s not everyone’s reality—especially for those who like pulling all-nighters. I’ve found that sleep is one of the biggest contributors to my performance. Sure, it’s easier said than done, but if you can manage even a few nights of proper rest leading up to exams, you’ll feel a lot more prepared. When I head into an exam, I go with a relaxed mindset, hoping for the best but knowing that a well-rested brain will work more efficiently than one running on caffeine and no sleep.

Study Habits: Different for Everyone

Everyone studies in their own way. Some people create meticulous notes, formula sheets, PowerPoints, or flashcards. For me, I’m all about pen and paper. I like solving problems on blank sheets, getting my thoughts out of my head and onto the page. Now, I’m not the most organized—I tend to overwrite on the same paper with different course material or random thoughts. It may not look pretty, but it works for me.

If you’re like me and sometimes your thoughts are racing in all directions, here’s a trick: Treat your mind like a program running multiple threads. When I get overwhelmed, I use a mental “task queue”—I prioritize the most important task, focus on it, and “dequeue” it by writing it down if I get stuck. I switch to the next task, and return to the first one once I have more clarity. This stops the mental race conditions (yeah, that’s the programmer in me talking!) and helps me stay focused.

Fueling Your Brain: Hydration and Good Food

Don’t forget the basics—hydration and good food. I always keep water with me and try to eat well during exam season. It’s easy to neglect proper meals when you’re cramming, but you’ll perform better if your body has the right fuel. Trust me, energy drinks and chips won’t cut it long term.

A Final Thought: Exams Don’t Define You

Here’s the most important thing I can tell you: a piece of paper does not determine who you are or what you will become. There will be easy exams and difficult ones—that’s inevitable. But your mental health and well-being should always come first. The stress you feel now is just a small piece of your journey, and if you consistently put in effort over time, that hard work will pay off. Looking back, you’ll see that one difficult exam was just a bump in the road of your personal growth.

To everyone reading this: You’ve made it this far in mechanical engineering or you’re planning to, which means you’re already incredibly smart and capable. Be proud of yourself. Give yourself a pat on the back, take care of your mind and body, and get ready to give your best shot to the exams ahead.

Good luck—you’ve got this! (╯▽╰ )
