In this project, students are tasked with building and programming a Waveshare Jetbot AI to navigate through a maze. The outcome from this project will allow us to build a robot that will find itself out an unknown area without driving manually. This is accomplished by using Robotic Operating System, SLAM Algorithm, and Jetson Nano.

Figure 1: Jetbot, Jetson Nano, and Lidar
- Jetson Nano which is the main computer that lets you run multiple neural networks in parallel for applications.
- Waveshare Jetbot AI that is installed with motors and connected to Jetson Nano.
- RP Lidar A1 that uses a system that measures distance data in more than 2000 times' per second and with high resolution distance output, which also provides a 360 degree scan field.
- Detailed physical Maze
Nice to Haves
- Robot scans entire maze and provides a map of which direction to go through the maze.
- Maps out the maze autonomously.
- The implementation of Odometry which is the use of data from motion sensors to estimate change in position over time.

Figure 3: Baseplate CAD Design
The car's electrical assembly consists of three main components:
- Jetson Nano – The single board computer (SBC) in charge of controlling the Jetbot AI.
- RP Lidar A1 – A 360 degree 2D laser scanner.
- DC Motors – Rotates the wheels to provide mobility.

Advice and Suggestions for the Future
- If using a bigger robot the maze needs to be much bigger.
- With more time, write a code to map the maze autonomously.
