Intermediate Robotics Track - 3 Months
Advanced logical thinking and intermediate robotics for Class 7-10. Master sensor-based robots.
Instructor: Sarvtra Expert
Detailed Project Manual
From Blocks to Real Code
In the Intermediate track, we move beyond the basics. Students will build their first Autonomous Robot that can "see" its surroundings. This curriculum is designed to foster logical depth and prepare students for engineering competitions.
Over 500+ students have used this track to win local STEM exhibitions!
Safety First
Always disconnect the power before changing circuit wires.
Ensure the motor driver is properly mounted to avoid short circuits with the metal chassis.
Use a multimeter if unsure about voltage levels.
Pro Tip: Read all instructions before starting the build to ensure a smooth making experience.
What's in the Kit?
Core Electronics
Chassis & Power
Step-by-Step Build Manual
Robot Base Assembly
- Fix the motors to the chassis using clamps.
- Attach the castor wheel at the front for balance.
- Mount the Arduino Uno using plastic spacers.
Expected: Mechanical robot base ready
Ultrasonic Sensor Setup
- Fix the sensor at the very front of the robot.
- Connect Echo to Pin 11 and Trig to Pin 12 on Arduino.
- Write a test code to print distance on Serial Monitor.
Tip: Keep the sensor clear of any dangling wires.
Expected: Sensor eyes ready
Motor Driver Wiring
- Connect motors to Out1/Out2 and Out3/Out4.
- Connect ENA and ENB to PWM pins for speed control.
- Common ground the battery, driver, and Arduino.
Expected: Power distribution ready
Logic Implementation
- Write an If-Else loop: If distance < 20cm, STOP and TURN.
- Else, go FORWARD.
- Test the turns (Left vs Right) to see which is more efficient.
Expected: Autonomous logic active
Field Testing
- Place the robot in a confined area with obstacles.
- Observe its behavior and adjust the turn duration in the code.
- Experiment with different speeds for better avoidance.
Expected: Working Obstacle Avoiding Robot!
Learning Outcomes
Course Curriculum
Extension Activities (Optional)
Add an IR sensor to detect edges (Table Edge Avoiding Robot)
Integrate a Buzzer to beep when an obstacle is too close
Manual control using a Smartphone (Bluetooth add-on required)
Teacher's Note
“This course bridges the gap between basic blocks and real-world coding. Ensure students understand why common ground is necessary.”
