SRV02 Gyroscope User Manual
2.2.3. Inner frame
This component is depicted by ID #3 in Table 1 and Figure 2. It provides support for the rotor and the
DC motor used to spin it. This frame itself is connected to an outer frame via two shafts at its two ends.
This allows rotation of the rotor and inner frame structure about these shafts.
2.2.4. Encoder for inner frame rotation measurement
This component is denoted by ID #4 in Table 1 and Figure 2. Digital position measurement of the inner
frame rotation about its support shafts is done using a US Digital optical high resolution (1024
counts/rev) encoder.
2.2.5. Support springs
These components are identified with ID #5 in Table 1 and Figure 2 and are two springs that are
attached to the inner frame at one end and to the outer frame base surface at another end. This
mechanism stabilizes the inner frame structure from undesired disturbances.
2.2.6. Gear mechanism
These components are identified with ID #6 in Table 1 and Figure 2. They are used to translate the
rotation of the inner frame and rotor disk structure to the shaft to which the encoder is connected to.
This mechanism introduces a 1:4 gear ratio from the frame shaft to encoder shaft that has to be taken
account when converting the encoder measurement to inner frame shaft rotation measurement.
2.2.7. Gyroscope module encoder connector
This component is identified with ID #7 in Table 1 and Figure 2 and provides measurement of the
gyroscope module deflection angle.
2.2.8. SRV02 plant
For more information on this component please refer to [1].
2.2.9. Support base plates
These components are identified with ID #9 in Table 1 and Figure 2. One of them to which the rubber
plastic pieces are attached is used for support and the second plate with the clamps is used to hold and
rotate the SRV02 and gyroscope structure with respect to the support plate.
2.2.10. Hold clamps
These components are identified with ID #10 in Table 1 and Figure 2 and are used to tighten the
SRV02 plant to the base support plates. This can be done by using an Allen key to tighten the screws of
each clamp.
2.2.11. Gyroscope rotation disk motor connectors
This component is identified with ID #12 in Table 1 and Figure 2 and connects to a power source on
