3. Program 'SetTrim_v1.0.spin' into the Propeller Control Board's EEPROM.
4. Open the Parallax Serial Terminal (PST.exe), and then set the COM port to the one connected to
Propeller Control Board and set the baud rate to 9,600.
5. Follow the instructions in 'SetTrim_v1.0.spin' to set the trims on the R/C transmitter.
Step 3: Calibrate the throttle and brake servos.
1. Open 'QuadRoverControl_v1.0.spin' and follow all directions in the comments.
Step 4: Check the servos and brakes before every use.
2. Load and 'QuadRoverNavigation_v1.0.spin' into the Propeller Control Board's EEPROM.
3. With the engine off and the Propeller Control Board's Power Switch all the way on (Propeller ON
and Servos ON), turn on the R/C transmitter and move the left joystick all the way up. The
brakes should fully engage.
4. If they do not, repeat Step 3: Calibrate the throttle and brake servos.
Step 5: Check the R/C radio system for signal quality and strength.
1. Load and run 'QuadRoverNavigation_v1.0.spin' into the Propeller Control Board's EEPROM and
have someone hold the R/C transmitter at the furthest distance that you will be using the radio.
2. Have them move the brakes and throttle and make sure that the servos respond smoothly.
3. If the servos do not move at all, the radio may not be strong enough.
4. If the servos make jerky movements, even if just occasionally, the signal is receiving too much
interference.
5. If either condition occurs, it must be remedied before the radio system can be used with the
QuadRover. Refer to your RC radio system's manual.
Step 6: Test the throttle-kill and no-signal conditions.
Before running the QuadRover, its control setup should be thoroughly tested:
1. With the engine off but the Propeller Control Board's Power Switch all the way on (Propeller ON
and Servos ON), move the joysticks on the R/C transmitter and check for corresponding
movements in the servos on the QuadRover.
2. If everything works appropriately, start the engine and run the same test again making sure that
the wheels move as expected.
3. Turn the R/C transmitter off and check to make sure that the engine stalls.
4. After everything is tested, the QuadRover should only be run in a safe, controlled environment,
following all of the Safety Precautions.
5. Before running the QuadRover in a new environment, repeat Step 5: Check the R/C radio
system for signal quality and strength to ensure that there is no radio interference.
