Gyroscopic precession engine for wearable devices

A wearable device comprising:

• a support structure including at least one attachment mechanism for attaching the support structure to a human body part;
• at least one gyroscopic precession engine coupled to the support structure, the gyroscopic precession engine, comprising:
• a first motor configured to rotate a wheel mount at a first angular velocity;
• at least one wheel rotatably coupled to the wheel mount and configured to spin at a second angular velocity;
• a second motor configured to spin the wheel at the second angular velocity based on an upcoming trigger event;
• and
• at least one motor controller coupled to the first motor and the second motor, the at least one motor controller configured to detect that the trigger event has occurred and rotate the wheel mount at the first angular velocity;
• wherein the wheel mount is configured to move in free space in response to a torque produced by a product of the first angular velocity of the wheel mount, the second angular velocity and a moment of inertia of the wheel, and
• wherein the support structure moves in response to a force produced by the torque.
