The 3 DOF Hover experiment provides an economical test bed to understand and develop control laws for flight dynamics and control of vehicles with vertical lift off.
3 DOF Hover
The 3 DOF Hover consists of a planar round frame with four propellers. The frame is mounted on a three degrees of freedom pivot joint that enables the body to rotate about the roll, pitch and yaw axes. The propellers are driven by four DC motors that are mounted at the vertices of the frame. The propellers generate a lift force that can be used to directly control the pitch and roll angles. Two of the propellers are counter-rotating, so that the total torque in the system is balanced when the thrust of the four propellers is approximately equal.
