Key Learning Outcomes

With this kit, students will:

• Understand core principles of robotics and motion control

• Gain hands-on experience with PID algorithms and sensor integration

• Learn modular design and how to build reconfigurable robots

• Develop real-world problem-solving and programming skills

• Apply theoretical knowledge in physics, math, and computer science

How to Use the Acrome Education Kit?

The Education Kit supports a step-by-step learning process, making it accessible for beginners, educators, and advanced users.

-Beginner Level: Drag & Drop Programming (Blockly UI)

• Blockly-based visual programming allows users to control motors and sensors without writing code.

• Ideal for high school students and first-time robotics learners.

Example: Move a motor forward for 5 seconds using Blockly.

-Intermediate Level: Python API for Robotics Control

• Write Python scripts to control motors, read sensors, and perform automated tasks.

• Great for university projects, mechatronics coursework, and industrial training.

Example:

set_motor_speed(left_motor=50, right_motor=50)  # Move forward
time.sleep(2)  # Wait for 2 seconds
stop_motors()  # Stop movement

-Advanced Level: AI, IoT & Industry 4.0 Applications

• Implement PID control algorithms for smooth motion.

• Integrate AI-based object tracking, real-time data logging, and IoT connectivity.

• Example: Use machine learning for autonomous robot navigation.

Real-World Applications

The Acrome Education Kit is designed for academic learning, research, and prototyping, with applications in:

STEM Education & University Labs – Robotics, automation, and programming courses. Industrial Training – Understanding servo motors, stepper motors, and real-time control. AI & Machine Learning – Develop autonomous robots with sensor fusion. IoT & Smart Automation – Create smart home systems and automated machinery.
