    The Quanser 3 DOF Hover system consists of a frame with four propellers. The frame is mounted on a three degree of freedom pivot joint that enables the body to rotate about the roll, pitch and yaw axes. Each propeller generates a lift force and the lift forces are used to control the pitch and roll angles.

    2.1.1 Quanser 3 DOF HoverOverall Components The components comprising the Quanser 3 DOF Hoversystem are labeled in Figure 2.1, Figure 2.2, and Figure 2.3, are described in Table 2.1. The motors, propeller assemblies, and encoders are described in more detail below.
  • Page 6 2.1.2 DC Motors (Components #2) The Quanser 3 DOF Hover has four DC motors: the front and back motors that mainly control the system about the pitch axis and the left and right motors that primarily move it about the roll axis.

    2.1.4 Encoders (Components #4 and #5) The Quanser 3 DOF Hover experiment has three encoders used to measure the angle of pitch, yaw, and roll axes. In quadrature mode, each encoder has a resolution of 8192 counts per revolution. Thus the effective position resolution is 0.0439 degrees about the yaw, pitch, and roll axes.

    Follow these steps to setup the 3 DOF Hover system: 1. Place the base of the 3 DOF Hover, Component # 11 shown in Figure 2.1, on a table or on the floor. 2. Assemble the body to the main base by aligning the pitch/roll encoder frame, i.e., the yoke shown in Figure 2.2 as Component #6, with the top of the base and tighten the thumb screws.

For instance, you may have a DAQ with more channels than the one presented in Figure 3.1 or have four single-channel amplifiers that do not require any Emergency Stop (in which case, you would omit connection #12).

  • Page 13: Testing And Troubleshooting

    This section describes some functional tests to determine if your system is operating normally. It is assumed that the Quanser 3 DOF Hoveris connected as described in Section 3.3. To carry out these tests, it is preferable if the user can use a software such as QUARC LabVIEW™...

    2048 counts. Make sure the details of the data-acquisition system being used is known. The counters on the Quanser DAQ boards measure in quadrature and therefore a total of four times the number of encoder lines per rotation, e.g., a 2048-line encoder results in 8192 integer counts for every full rotation.
