1. Introduction
Nowadays, technological education such as VR, kids programming,
and artificial intelligence, has become mainstream in educational
industry. Thereby, people attach importance to STEM education.
Arduino is pretty notable in Maker education.
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,

www.keyestudio.com
Keyestudio team has designed a mini tank robot. The tank robot
has a processor which is programmable using the Arduino IDE, to
mapped its pins to sensors and actuators by a shield that plug in
the processor, it reads sensors and controls the actuators and
decides how to operate.
15 learning projects, from simple to complex, will guide you how to
make a smart tank robot on you own and introduce the detailed
knowledge about sensors and modules. Simultaneously, it is
the best choice if you intend to obtain a DIY robot for learning
programming, entertainment and competition requirement.
2. Features
1. Multi-purpose: Obstacle avoidance, follow, IR remote control,
Bluetooth control, light following, ultrasonic follow and displaying
face emoticons.
2. Simple assembly: No soldering circuit required, complete
assembly easily.
3. High Tenacity ： Aluminum alloy bracket, metal motors, high
quality wheels and tracks
4. High extension: expand other sensors and modules through
motor driver shield and sensor shield

5. Multiple controls: IR remote control, App control(IOS and
Android system)
6. Basic programming：C language code of Arduino IDE.
