+A Hexapod Robot using Raspberry Pi Zero W
 
-You can use any mobile phone (iOS or Android) to control the movement of hexapod (move foreward, backward, etc...).

 ## Brief introduction
 
 * **Remote control** is done via `BLE` of `Linkit 7697`
-* It has 6 legs, each leg has 3 joint. So there are total `18` **Servo motors** (TowerPro `MG92B`)

 * Linkt 7697 dont have so many **PWM control**, so NXP `PCA9685` x 2 are used to control these servo motors
 * **Power** comes from a `2S Lipo battery (7.4v)`. Also 7 x `mini360 DC-DC` step down voltage regulator are used. One to provide `5V` to Linkit 7697, The other six to provide `6V` to each legs (1 mini360 serve 3 servo)
 * The **body** is 3D printed PLA. I use `Prusa i3 MK2S`, a really good 3D printer.
