You can control servos directly from the Pi. They need one gpio per servo (control line) so you'd need to use 14 of the Pi's 21 gpios. Doesn't leave a lot of gpios to connect additional sensors though.

You can buy I2C chips to drive servos. Typically they let you drive 16 servos per chip. You just connect the chip to the Pi's two I2C gpios.

You can look at Chinese or Adafruit I2C, Pololu USB/Serial servo controllers. Chinese ought to be the cheapest.
