3-DOF Hover CAD Design

Hello friends! In this article, we will share about 3 DOF Hover and how to design it using Solidworks Software. Happy Reading fella!

The 3 DOF Hover consists of a planar round frame with four propellers. The frame is mounted on 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. The total torque generated by the propeller motors causes the body to move about the yaw axis. 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. The voltage signals going to the motors, as well as the pitch and yaw encoder signals, are transmitted through a slip ring. The slip ring removes the need for wires and allows for 360 degrees free motion about the yaw axis. Furthermore, it reduces the amount of friction and loading about the moving axis.  read more
