INTRODUCTION

“Maia Jr” is a category of automated miniature vehicle made created by the MAIA team. It is well regarded for its simplicity and use as a learning tool for new developers and hardware enthusiasts alike.

FEATURES

The vehicle contains the following:

• (1x-3x) ultrassonic sensors;
• (1x) Arduino board;
• (2x) Motors;
• (1x) 5-12V CC Motor controller (M298N module);
• (1x) 5V mobile rechargeable battery;
• (1x) Battery charger regulator port (USB-C);
• (1x) Chassis
• (2x) mountable rubber wheels

FUNCTIONALITY

The vehicle is designed to avoid obstacles in real time by using the distance variation between ultrassonic sensor readings. The positioning of these sensors is crucial. For 3 sensors, one must be placed forwards from the center, followed by two additional sensors on both sides, rotated about 30° clockwise and counter-clockwise. If an object approaches the sensors, the vehicle will rotate accordingly until it finds a clear view to continue moving forwards.

RELEVANCE

The project is relevant for the following reasons:

• Allows the student to learn the functionality of Arduino, applications and how it interfaces with external input.
• Encourages problem-solving skills by developing a solid firmware capable of utilizing sensor feedback to the best extent.
• Introduces the student to hardware and electronics.
