Project: Gyrosphero

prusaprinters

<p>This project demostrates the basic functionality of gyroscope. A gyroscope is a spinning wheel or disc in which the axis of rotation is free to assume any orientation by itself. When rotating, the orientation of the axis is unaffected by tilting or rotation of the mounting, according to the conservation of angular momentum. Because of this, gyroscopes are useful for measuring or maintaining orientation.

These circles can by printed in one piece. Each circle is a substraction of two spheres. Dimensions are calculated for Sphero as a gyroscope as rotor.</p> <h3> Project: Gyrosphero - gyroscope powered by sphero</h3> <p><strong>Overview &amp; Background</strong></p> <p>By completing this project one can observe and practice the prinicple of gyroscope.</p> <p>Within mechanical systems or devices, a conventional gyroscope is a mechanism comprising a rotor journaled to spin about one axis, the journals of the rotor being mounted in an inner gimbal or ring; the inner gimbal is journaled for oscillation in an outer gimbal for a total of two gimbals.</p> <p>The outer gimbal or ring, which is the gyroscope frame, is mounted so as to pivot about an axis in its own plane determined by the support. This outer gimbal possesses one degree of rotational freedom and its axis possesses none. The next inner gimbal is mounted in the gyroscope frame (outer gimbal) so as to pivot about an axis in its own plane that is always perpendicular to the pivotal axis of the gyroscope frame (outer gimbal). This inner gimbal has two degrees of rotational freedom.</p> <p>The axle of the spinning wheel defines the spin axis. The rotor is journaled to spin about an axis, which is always perpendicular to the axis of the inner gimbal. So the rotor possesses three degrees of rotational freedom and its axis possesses two. The wheel responds to a force applied about the input axis by a reaction force about the output axis.</p> <p>The behaviour of a gyroscope can be most easily appreciated by consideration of the front wheel of a bicycle. If the wheel is leaned away from the vertical so that the top of the wheel moves to the left, the forward rim of the wheel also turns to the left. In other words, rotation on one axis of the turning wheel produces rotation of the third axis.</p> <p>source Wiki <a href="https://en.wikipedia.org/wiki/Gyroscope">https://en.wikipedia.org/wiki/Gyroscope</a></p> <p><strong>A gyroscope in operation. Note the freedom of rotation in all three axes. The rotor will maintain its spin axis direction regardless of the orientation of the outer frame.</strong></p> <p><strong>Objectives</strong></p> <ul> <li>basic physical principles</li> <li>principle of gyroscope</li> <li>using of gyroscope</li> <li><p>design of simple machine<br/> <strong>Audiences</strong></p> <p>The principle of gyroscope is usually part of the curriculum of secondary schools (13-years old pupils).
