Robotics Path A
Line Tracer Delivery Mission
Build and program an autonomous robot using the MRT 401 course set that follows a black line, delivers objects, and returns safely.
Your Mission 🎯
Mission Objectives
Build an autonomous robot that can complete the following mission sequence:
- Follow a black line
- Deliver two objects to the required locations first
- Then carry two objects
- Return to the designated area
- Stop automatically by itself
The robot must complete the mission with consistent and logical behaviour through programming and sensor logic, not manual control.
🔴 Required Mission (70%)
- Complete line tracing from start to end
- Deliver 2 objects to marked locations
- Carry 2 objects back to base
- Auto-stop at finish point
⭐ Bonus Mission (30%)
- Complete within time limit (speed bonus)
- Handle line intersections correctly
- Smooth servo operation for object handling
- Consistent results across multiple runs
Hardware Rules ⚙️
The robot must use the MRT 401 course set and include:
✅ 2 Motors✅ At least 1 Servo✅ Fewer than 5 IR Sensors
⚠️ Exceeding the sensor limit or using non-MRT components will result in disqualification from this category.
Evaluation Criteria 📊
| Criteria | Beginning (1) | Developing (2) | Accomplished (3) | Exemplary (4) | Weight |
|---|---|---|---|---|---|
| Mission Completion | Cannot follow line | Follows line but fails delivery | Completes required missions | Completes all missions + bonus | ×6 = 24 |
| Control Accuracy | Erratic movement | Basic tracking with wobble | Smooth, accurate line following | Precise turns, stops, and transitions | ×5 = 20 |
| Mechanical Design | Unstable build | Basic structure | Sturdy, functional design | Elegant, efficient engineering | ×4 = 16 |
| Coding Logic | Minimal code | Basic sensor reading | PID or adaptive logic | Advanced, well-commented code | ×5 = 20 |
| Presentation | No explanation | Brief text | Video + photos + description | Detailed process documentation | ×5 = 20 |
Total: 100 points
Submission Requirements 📦
- A mission video (MP4, max 3 min)
