In the past few years, we have covered plenty of hybrid drones here. The Duawlfin is also worth a look. It is a drone that can fly and move on the ground. It can climb slopes of up to 30 degrees. It can also fly with agility. Unlike other drones that have similar mechanisms, this one doesn’t rely on additional actuators. It only uses quadrotor motors and a differential drivetrain with one-way bearings
