1. Product introduction

1.1 Introduction

Nowadays, technological education such as VR, kids’ programming, and artificial intelligence, has become a mainstream in educational industry. Thereby, people attach more importance to STEAM education.

As Arduino is notably famous in Maker education sector. Keyestuido surf this current and launch a smart mini tank robot which is a combination of Arduino and programming.

So what is Arduino? Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online.

Based on this, Keyestudio team has designed a mini tank robot. It has a processor which is programmable using the Arduino IDE, to map its pins to sensors and actuators by a shield that plug in the processor, and it reads sensors and controls the actuators and decides how to operate.

It can perform multiple functions like obstacle avoidance, IR remote control, BT control, light following and so on.

Detailed 15 learning projects, from simple to complex, which guide you to build up your own smart mini tank robot and provide the basic knowledge of sensors and modules. Moreover, it is the best choice for graphical programming education.
