Rotatable External Cage for Vehicle

A barrier assembly for suspending a propulsion platform therein such that the barrier assembly is freely rotatable relative to the propulsion platform about at least a first axis of rotation, the barrier assembly comprising:

• a plurality of rods;
• a plurality of vertex connectors, the plurality of rods being connected by the plurality of vertex connectors to form an external cage having a shape, wherein the external cage is configured to maintain the propulsion platform within an internal volume of the external cage;
• and
• a gimbal assembly configured to operably couple the external cage to the propulsion platform in a secured position while enabling relative rotational movement between the propulsion platform and the external cage about the first axis of rotation.

A vehicle comprising:

• a propulsion platform, the propulsion platform comprising:
• a body;
• a motor supported by the body;
• and
• a propeller operably coupled to the motor, wherein the motor is controllable to control rotation of the propeller;
• an external cage operably coupled to the propulsion platform, the external cage comprising a plurality of rods connected by a plurality of vertex connectors, wherein the propulsion platform is disposed within the external cage;
• and
• a gimbal assembly that operably couples the propulsion platform to the external cage thereby securing the propulsion platform to the external cage while enabling relative rotational movement between the propulsion platform and the external cage about a first axis of rotation, a second axis of rotation, and a third axis of rotation;
• wherein the first axis of rotation, the second axis of rotation, and the third axis of rotation are each perpendicular to each other.
