How ChefBot’s hardware works’?

We can explain how ChefBot's hardware works using the following block diagram. This is an improved version of our first block diagram, as it mentions the voltage of each component and its interconnection:

Detailed block diagram of Chefbot's hardware

The main aim of this chapter was to design the hardware for ChefBot, which included finding the appropriate hardware components and learning about the interconnection between each part. The main functionality of this robot is to perform autonomous navigation. The hardware design of the robot is optimized for autonomous navigation.

The robot drive is based on the differential-drive system, which consists of two motors and two wheels. There are caster wheels for supporting the main wheels. These two motors can move the robot to face in any direction on a 2D plane by adjusting their direction and speed of rotation.

For controlling the velocity and direction of the wheels, we have to interface a motor controller, which...
