#Arduino Quadruped Robot



Arduino Quadruped Robot the project delivered from upstream project [RegisHsu](http://goo.gl/H1vvwW)'s spider robot. This project has been redesigned in 3d printed parts eg: didn't glue servo holder with tibia and fumer, resize body to fit [12300 LIPO battery](http://goo.gl/VmvYhv). You don't need to make a bluetooth remote control anymore but you can control robot using [Android App Bluetooth Joystick](https://github.com/anoochit/android-robot-bt-joypad) instead, [get app from Google PlayStore](https://goo.gl/MF46JS). 



New command mode (see source code for detail)



* Test mode - test robot movement in bluetooth command

* Sonar mode - wave your hand in front of ultrasonic sensor to wake up robot

* Free walk mode - walk and avoid obstacle in 20cm like robot vacuum

##Assemply 



Assembly the printed parts for 4 legs with servos, don't screw servo axis at this time, then assembly legs with body.

Assemply electronic parts (schematic'll add later)



 * Servo pulse pin connect to Arduino Nano pin D2-D13

 * Servo VCC and GND connect to regulator output

 * Bluetooth HC-05 Vcc to to Arduino Nano 5V pin, GND, RX-TX and TX-RX

 * Arduino Nano, Vin and GND connect to regulator output 5v

 * Use dc jack connect with LIPO battery

 * Connect battery to input of regulator for stepdown output to 5v



Group servo wire use order Fumer, Tibia, Coxa, connect servos to arduino pin for each leg



 * Lelf Front connect to pin D2-D4

 * Lelf Back connect to pin D5-D7

 * Right Front connect to pin D8-D10

 * Right Back connect to pin D11-D13



Flash leg_init.ino script to initial servo angle then screw tight all servo axis, leg position like picture.

Flash spider_robot.ino to Arduino, Finish.



##How to play



Clone joystick app build and install or [get app from Google PlayStore](https://goo.gl/MF46JS) to your mobile phone, open app, swipe and choose connect menu, choose robot bluetooth to connect.
