  • Circuit connections to the DAQ require a cable and a facility for connecting to individual pins. An efficient system is based on a National Instruments Connector Block (CB-68LP) and a basic circuit board as shown here. Connections to the circuit board from the connector block are made one time. The two resistors of the circuit are connected to output channels 0 and 1, respecively. Thus, for example, Chan0_out, as noted, is dedicated to the top strip on the circuit board. The bottom top strip is associated with Chan0_in, and so forth....

  • Increasing the iMEMS Accelerometer’s Output Scale Factor Figure 15 shows the basic connections for using an external buffer amplifier to increase die output scale factor. The output multiplied by the gain of the buffer, which is simply the value of resistor R3 divided by RI. Choose a convenient scale factor, keeping in mind that the buffer pin not only amplifies the signal, but my noise or drift as well. Too much pin can also cause the buffer to saturate and clip the output waveform. Note that the “+” input of the external op amp uses the offset null pin of...

  • The Driving Mechanism works the same as the Steering Mechanism. When a command is received to go forwards the SCRX2BC creates a voltage at pin 11 which turns on Q2. This then turns on Q5 and Q8 and current flows from the batteries through Q5, then through the driving motor, and then through Q8 to ground. Similarly to go backwards the voltage is created at pin 10, and Q3, Q6, and Q7 are turned on. The small gear on the Motor drives the Middle Gear, which drives the gear on the rear wheels axle, making the wheels move. Note that the gears on the Motor...
