Three different intermediate-level Arduino projects are introduced as a way of exploring the capabilities of the open-source microcontroller platform. First, an Arduino-based gimbal was proposed, with a video demonstration using the MPU6050 inertial measurement unit (IMU). Many commercial gimbals use similar sensors and methods for balancing objects and controlling angular and translational movement. Second, a mechanum wheels robot was presented as a way of creating a more omnidirectional robotic car, vs the normal one-dimensional movement associated with Arduino and robotic cars. Finally, an Arduino-based hovercraft was shown with motors and an Arduino at the center.
