Developing personality

The personality is what makes the robot more alive. Adding personality to it makes it more fun and likable. This section focuses on some ideas that will help you create your own unique personality for your robot.

Circuit upgrade

The tiny circuit that we made can be split into two; one along each side of the Arduino connected to a common GND and power. Additionally, more header pins can be added to accommodate more servos (the tail and head) in order to organize the wires better.

First, for this, cut out a long circuit board with a row size of about 6 pins.

Following the previous circuit's design, create this circuit:

To link the left and right side, small pieces of wires are soldered; one for the GND and another for the power, like this:

Attach these circuits on either sides of the Arduino MEGA in this fashion:

The finished connections will look like this:

Body upgrade

To be perfectly honest, the robot doesn't resemble a dog at all. Sure, it walks on four feet, but it doesn...
