Nrf Hexapod

This is a hexapod using [nRF52 DK](https://www.nordicsemi.com/eng/Products/Bluetooth-Smart-Bluetooth-low-energy/nRF52-DK). It can be controlled using bluetooth low energy (bluetooth smart). See [this blog](https://devzone.nordicsemi.com/blogs/941) describing the hardware.

Suguru has been added to the "feets" in an attempt to get better grip, using rubber or eraser might be a better option. The part between middle and bottom servo (femur) had to be glued to the servo horns to make the legs more rigid.
