Systems and methods relate to a vertical takeoff and landing (VTOL) platform that can include a stator and a rotor magnetically levitated by the stator. The rotor and stator can be annular, such that the rotor rotates about a rotational axis. The stator can include magnets that provide guidance, levitation, and drive forces to drive the rotor, as well as to control operation of rotor blades of the rotor that can be independently rotated to specific pitch angles to control at least one of lift, pitch, roll, or yaw of the VTOL platform. Various controllers can be used to enable independent and redundant control of components of the VTOL platform.

Systems and methods of the inventive subject matter are directed to control systems that create virtual mass in a haptic feedback system. Embodiments include a jog knob coupled with a PCB stator motor such that the PCB stator motor can be controlled to give the jog knob a feeling of mass that is different from its actual mass. Thus, a system of the inventive subject matter can be configured to continue a rotation as if it has a higher mass than it actually has, resulting in smoother rotations that last longer. This functionality can be useful to, for example, remotely control a camera's movements while still giving a user the feel of a comparable mechanical system.
