This is a hexapod robot based on Smallp Tsai's hexapod-v2-7697 project. This project reused most of the mechanism designs in the original project, but with a totally redesign on the circuits and softwares.

Remote control is done via BLE of Linkit 7697
It has 6 legs, each leg has 3 joints. 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
