Hexapod v2 using Linkit 7697
|
|
|
|
This is a Hexapod project.
|
|
|
|
You can use any mobile phone (iOS or Android) to control the movement of hexapod (move foreward, backward, etc...).
|
|
|
|
See demo video: https://youtu.be/NJ7DdDEcq3U & https://youtu.be/To2Y6Mhu-CE to get the idea.

## 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.
|
|
* Everything (3D STL, PCB schematic, 7697 source code) are included in the project under **GPL license**, Happy making!

## Skill requirement
|
|
|
|
If you want to make one hexapod by yourself. You should at least knows how to:
|
|
|
|
* Mechanism part
|
|
* Use `3D printer` to print a model.
|
|
* Able to adjust 3D model to fit your custom need.
|
|
* Electronics
|
|
* Make a `PCB` (suggest to use professional PCB services)
|
|
* Soldering `SMD` component (0805 and TSSOP28)
|
|
* How to use/charge/store `LIPO batteries`
|
|
* Software
|
|
* Use `Linkit 7697` (ie. upload and run any program)
|
|
* Use `LRemote` to communicate 7697 and your mobile phone
