Arduino Balancing Robot

By partnering with ROBOTICS 3D- BORN ROBOTICS OPEN SOURCE PLATFORM   is the new robotic platform 4WD ARDUINO UNO that interacts with your Android App via bluetooth.

The basic version allows you to experience the basics of robotics applied to a platform 4WD

The robot "base" consists of:  

• Arduino Uno Rev3
• Dagu 4WD Magician Chassis
• 2A Motor Shield
• ULTRASONIC SENSOR HC-SR04
• 1 BUZZER
• 1 BRACKET X SR04
• 1 PORTABATTERIE
• 1 BLUETOOTH MODULE
• 10 jumper M/F
• 1 jumper a Y 1M/2F

Thanks to sketch provided as examples, can be tested step by step the basic functionality of the 4wd, in particular you can do:

• ENGINE TEST
• TEST AUDIO
• ULTRASOUND TEST
• TEST BLUETOOH

Among the applications that you can make it is also included Theremino (included in the basic version) other being sviiluppo.

Android4WD is both the Arduino sketch is the mobile application that allows the basic version to control your TOADS.

With MIT App Inventor 2 you Customize your Android application to control your robot
