Raspberry Pi Hexapod HD

I built this hexapod type robot using the Raspberry Pi B+. The electronics used include 1 Raspberry Pi, 2 Adafruit 16-Channel Servo Driver controllers, 18 Tower Pro MG90S Micro Servos, and one basic wifi adapter. The program was written in python 2.7.8, and uses a wireless ssh connection to connect to the Pi from my computer for the user control. Currently I am using two separate wired power sources; one 5V 4A power supply for the servos, and one 5V 1A power supply for the Pi. The frame was cut from pieces of 1/8 inch thick aluminum 6061. This is a work in progress and I will be implementing a wireless pushbutton type remote control in the near future. This is my very first robot, and any comments, questions, or suggestions would be greatly appreciated. Thanks for watching.
