Autonomous Pickup and Delivery Robot

Autonomous Pickup and Delivery Robot
From September to December of 2017 I collaborated with a team of four mechanical and electrical engineering students to design and build a robot for our course, Mechatronics Principles. The objective of the project was to build a robot that could localize from a random starting point in a known environment (a maze), and navigate to find an object in a loading zone, pick up the object, and transport it to one of four delivery zones. During this project, I created 3D CAD models of all components and sub assemblies, prepared models and drawings for 3D printing and laser cutting, selected and integrated sensors and motors, assembled the robot, and wrote the obstacle avoidance, object detection, and sections of the navigation algorithms in Arduino and MATLAB. After performing over 60 hours of testing and troubleshooting, the robot's performance was extremely robust, and resulted in a perfect score in the competition.
