Cute Bluetooth-Controlled Quadrupled robot

Hi everyone, this is the design for my robot of spider (quadrupled) that I have been collaborating with 1 of my friends - Tai Ngo - at RMIT University. We've been on this project for almost 2 semesters (approximately 6 months). The target is to create a four-legged robot from 3D printing and then implement embedded system to control it.
The main components that we used:
 - Arduino Nano
 - 2 Li-po battery packs (each 3.7V)

 - A step down transformer (8V → 6V)

 - Jumper wires

 - Switch

 - Bluetooth module

 - Breadboard

 We were inspired from an idea on the internet, however, due to our own design that must require new design. We keep what are still useful and turns out work pretty well. Please have a look at our project images for more information. The robot now can be connected and controlled through Bluetooth. We are still working on more on the code for better performance but so far it did meet with our requirement of purpose.

ENJOY!
