A ROBOT DOG buit out of PCBs

if you want to know more about this robots' features, and capabilities, how I designed and built it, watch the video above.

what is it?

can you build a robot entirely out of PCBs? this is the question I asked myself when I decided to build this robot. it is a small robot dog entirely built using PCBs, it was designed with the idea of making a small, clean, smart, and capable robot dog that everyone can easily build at home using off-the-shelf components like servo motors, an Arduino, and other readily available electronics. since this robot is built using PCBs the vast majority of the connections between the components can be integrated into the robot structure making wired connections necessary only between the legs joints. this robot features an hc05 Bluetooth module that allows it to be controlled via a smartphone, all the code is processed by a small Arduino nano that controls the eight mg90s servo motors. This robot dog is also packed with features, in fact, it will not only be able to walk, but it will also be able to know when its feet are touching the ground thanks to the pivoting feet that act as a small button, this will allow this dog to easier navigate through rougher terrain without getting stuck or flipping over. this robot also features a module bay to which a variety of modules can be attached to further expand the capabilities of this small dog, such as a robotic arm or an obstacle avoidance sensor.

how it's built?

the coolest thing about this robot is that, since it is built using PCBs, it can be assembled by soldering together the individual PCBs with the help of a 0.8mm solid copper wire; in this way, while connecting the structural part of the robot, you will also be making the necessary electrical connections needed to connect all the electronic components together. for that reason, the only tools needed to assemble this small robot dog are a soldering iron, some pliers, and a wire stripper. This project is still a work in progress, because of that I won't share the code and the PCB files until I've finished it, stay tuned!

here are some pictures of it:
