# Introduction to Robotics

Princeton University

MAE / ECE 345, COS 346, MAE 549

# Course description

Robotics is a rapidly growing field with applications including unmanned aerial vehicles, autonomous cars, and robotic manipulators. This course will provide an introduction to the fundamental theoretical and algorithmic principles behind robotic systems. The course will also allow students to get hands-on experience through project-based assignments with the Crazyflie quadrotor. Topics include:

- Feedback Control
- Motion Planning
- State estimation, localization, and mapping
- Computer vision and learning
- Broader topics: Robotics and the law, ethics, and economics

This course is aimed at undergraduate students (primarily juniors and seniors). The graduate-level track (MAE 549) is aimed at first-year PhD students.

# Course prerequisites

Multivariable calculus, linear algebra, basic probability, basic differential equations, some programming experience (this course uses Python).

Hardware

The assignments for the course (provided below) include theory, programming, and hardware implementation components. For the hardware, we use the Crazyflie drone from Bitcraze. This is a lightweight drone (27g) with open-source software. The feedback control and motion planning hardware assignments can be completed with the following parts list:

- Crazyflie 2.1 drone
- Flow deck v2
- Crazyflie PA radio
- Spare parts (if necessary)

For the final project, students program the drones to perform vision-based navigation. We attach cameras to the drones, which transmit images in real-time to a receiver unit plugged into to a laptop. Completing the final project requires the following additional parts:
