1. What did you do in the activity?
I worked with my team to identify duplicate cards, discussed possible trade options, and communicated with other teams to find a suitable exchange. Since we were allowed only one trade in total and had a 10-minute limit, we planned carefully, negotiated with another team, completed our single card exchange, and then organized our final set before time ended.
2. Did the activity help you? How?
Yes. I learned to communicate better by discussing with my team and interacting with other teams to make decisions quickly.
3. Any challenges you have faced?
Yes. The main challenges were the limited 10-minute time and being allowed only one trade, which made it difficult to decide the best strategy quickly. It was also challenging to find a team willing to exchange the card we needed.
4. Share your reflections here.
The activity was engaging and helped me improve my communication and teamwork skills. Working under time pressure taught me to think quickly and collaborate better with others.
1. What is your understanding of the sewage problem in Bangalore?
Bangalore faces a growing sewage problem, threatening the city. Rapid growth and urbanization lead to excessive sewage, overwhelming infrastructure. Untreated sewage contaminates water sources, causing pollution, health risks, and environmental damage. Immediate action is needed to taken treatment facilities, research solutions, and implement sustainable waste management.
2. What are the root causes of this problem?
The root causes of this problem include: too many people, businesses breaking rules, and citizens lacking knowledge of proper waste disposal habits. Other contributing factors are rapid population growth, old pipes and treatment plants. The situation worsens when industries ignore government regulations, polluting water and overloading facilities. Furthermore, poor public knowledge about proper disposal methods leads to blocked pipes, causing overflows. Chemical factories pose a critical danger, as their toxic waste kills cleaning bacteria in treatment plants, corrodes pipes, and harms aquatic life due to the lack of required pretreatment.
3. What are the possible solutions for this?
To fix the pollution, we need strong control measures. This means making sure factories treat their toxic waste first and giving harsh penalties if they don't. We also need to fix and maintain our infrastructure. Teaching people how to properly dispose of waste is super important. Industries should have their own sewage systems. We need to plan new buildings and population growth carefully, and have safe places for chemical waste.
4. Share your reflections here.
I've found a big problem, mainly in those huge cities. It's a major issue for cities worldwide, because of things like complicated infrastructure and super fast growth. Now I'm going to figure out how this problem shows up in these cities and come up with some good solutions.
1. Describe the problem.
Street lights in many areas remain switched on throughout the night even when no pedestrians or vehicles are present. This results in unnecessary electricity consumption, increased operational costs, and avoidable environmental impact. The lack of automation or smart control means lighting is not adjusted based on real-time usage. Addressing this issue can significantly reduce energy wastage by ensuring street lights operate only when needed, while still maintaining public safety and visibility.
2. Mention which all disciplines are involved.
Electrical Engineering, Electronics Engineering, Computer Science / IT, Mechanical Engineering
This module is vital because as it prepares for the project. It specifically focuses on teaching key professional skills, such as working effectively in a team, setting clear goals, managing time efficiently, and mastering clear communication and professional interaction.
In your opinion, what are the benefits of working in a team?
Benefits of teamwork
Can you provide examples of how teamwork contributes to the success of a project?
1. What is scrum methodology and how does it fit into the agile framework?
Scrum is a super helpful, easy way to manage tough projects. It follows Agile ideas and helps teams get things done by breaking them into small bursts called sprints. During sprints, a team with all the skills needed works together to make something useful. The whole thing is about being open, checking in, and changing things up as needed through meetings, and it includes roles like a Product Owner, Scrum Master, and developers.
2. What is a sprint in the context of Agile development?
In Agile development, especially with Scrum, a sprint is like a short, timed burst, usually lasting 1 to 4 weeks. It's the project's main rhythm, giving a specific time to finish important tasks, which helps get rid of any problems and makes the project a success.
3. How do you envision using Agile principles, scrum, and sprint in your course project?
We'll divide the project tasks, giving each team member specific things to do. This way, we can easily adjust and check in often. We'll have quick discussions to make sure everyone's on the same page. After each one, we'll show our progress, get feedback, and plan what to do next.
1. What were your initial thoughts and feelings about the activity?
My first thought was to make a strong base. I figured out how to join the sticks to make the inside frame, and then built the main part of the car around that.
2. What challenges did you encounter during the activity?
I faced a challenge designing the steering mechanism.
3. How did your team approach problem-solving and decision-making?
My team assessed the necessary materials and considered efficient problem-solving approaches. We then decided to implement a specific solution, which we believed would resolve the issue effectively.
4. What did you learn from the activity that you can apply to future projects or teamwork situations?
I learned that you can't do a project alone - it takes everyone's skills. Each person has a part to play, and a team is key. I know now that it's super important to get along with your team, communicate well, set goals, manage our time, plan things out, make decisions, build something good, and support each other.

Design and develop an automatic circular curtain opening and closing system for a statue that can operate smoothly and safely. The system should automatically open and close light to medium-weight curtains in smooth circular motion within 10 seconds using a motor speed control mechanism and obstacle detection sensor for safety. It should ensure easy and effortless operation, compact installation, and smooth, steady movement. The system must operate on an AC power supply (220–240 V), use a circular track or guide rail system, and have a durability of about 5 years. The total installation cost should be between ₹1500 and ₹2500, ensuring safe and reliable operation without risk to users.
Design and develop an automatic circular curtain opening and closing system for a statue to ensure smooth and safe operation. The system should open and close light to medium-weight curtains in a circular motion within about 10 seconds. Various concepts are generated by selecting appropriate sub-functions and means such as sensors, control systems, power supply, actuators, and transmission systems. The system may operate using light sensors, motion sensors, or manual input. Control can be achieved through switch, timer circuit, remote control, or web-based systems. It should operate on suitable low-voltage power sources such as battery, adapter, or solar power. A circular track or guide rail must be used to ensure smooth and continuous curtain movement. Proper direction control and safety should be ensured using H-bridge or motor drivers along with limit switches or obstacle sensors. The system should be compact, cost-effective (₹1500–₹2500), durable for about 5 years, and easy to install and operate.
Design and develop an automatic circular curtain opening and closing system for a statue with an integrated IR-sensor based detection system and Arduino control logic. The system will use a high-torque 12V Gear Motor and a professional Circular Rail system to ensure smooth, consistent torque and safe circular motion within 10 seconds. Power will be managed through a regulated 12V 2A Adapter, ensuring reliable year-round operation. Safety features will include dual hardware Limit Switches and a software-based Obstacle Detection system for comprehensive collision avoidance. The final solution is optimized for a ₹2500 budgetary constraint, designed for a 5-year maintenance-free lifecycle with a priority on safe, easy, and effortless operation for high-traffic or hard-to-reach installations.
