Claim:
1. A single-drive multi-axis MEMS gyroscope for detecting movements in an orthogonal coordinate system having X-, Y-, and Z-axes, the single-drive multi-axis MEMS gyroscope comprising: axial gyroscopes comprising proof masses; first and second sets of driving masses configured to be driven into oscillation relative to each other in a first driving direction that takes place along a first axis of the X-, Y-, and Z-axes; and a set of joints connected to at least one of the first and second sets of driving masses to distribute driving forces of the first and second set of driving masses in the first driving direction, the set of joints is configured to transfer the oscillation and the driving forces of the first and second sets of driving masses in the first driving direction into driving forces that oscillate the proof masses of the axial gyroscopes in second driving directions, at least some of the second driving directions being at angles relative to the first driving direction, wherein each of the second driving directions is orthogonal to a respective sense direction of the axial gyroscope associated therewith, and each of the sense directions is orthogonal to a respective second axis of the X-, Y-, and Z-axes about which the axial gyroscope associated therewith detects rotation, such that in the event of a rotation about the respective second axis of any one of the axial gyroscopes, a Coriolis force is generated in the sense direction thereof.
