3D Printed Differential Drive Robot with LiDAR and 3D Depth Camera

This paper presents the design of a 3D printed mobile differential drive robot with LiDAR and 3D depth sensing. The robot is designed to be low cost and easy to build, making it suitable for educational and research purposes. All the main structures of the robot are 3D printed while the parts used in the robot are from off-the-shelf components. All the design files and source code used in this project is shared in the github repository. The robot is equipped with a LiDAR sensor for mapping and navigation, and a 3D depth sensing camera for object recognition. Robot Operating System (ROS) running on an Intel single board computer serves as the middleware for all robot control operations. The developed robot is able to run simultaneous localization and mapping (SLAM) and perform autonomous navigation. Design files and the software for the robot can be obtained from the github reposi-tory https://github.com/dannyngweekiat/3D-Printed-Differential-Drive-Bot.
