Best way to build it yourself is using this set as a starting point: [ Ссылка ]
What I did is add 4 servo's and the code you find in the link. Mine uses 16 HS-645-MG, because of the weight. A also added an accelerometer and 4 footsensors, but you can disable this easily in the code.
Hope this helps.
