MY COPTER INSTRUCTION MANUAL
Om sree sainathayanamaha MY COPTER INSTRUCTION MANUAL INTRODUCTION:Thank you for purchasing the my copter quad board version 5.0. The my copter board is a completely integrated quad control board with a 6DOF correction capability. The my copter board is equipped with a 3axis gyro scope and accelerometer (MPU6050) with DMP enabled which gives an accurate correction upto 0.1 degrees . The my copter board is capable of being outfitted with a zigbee module , DC motor controller , LCD and buzzer for low battery monitor alarm. The my copter board has an inbuilt kalman filter (1ST order predictive) and a complementary filter. The board has a full 3 cycle PID loop which gives it the capability to react fast and with extreme precision. SETUP AND WIRING:RECEIVER CHANNEL ASSIGNMENT:1) CH1 -> CHANNEL 1 OF RECEIVER (AIL CHANNEL) 2) CH2 -> CHANNEL 2 OF RECEIVER (ELE CHANNEL) 3) CH3 -> CHANNEL 3 OF RECEIVER (THR CHANNEL) 4) CH4 -> CHANNEL 4 OF RECEIVER (RUD CHANNEL) 5) The motor and esc wires have to fitted in the slots provided such that the WHITE / ORANGE WIRE of the esc corresponds to the S column of -+SS printed on the board Please refer to the diagram below:- Om sree sainathayanamaha MOTOR CHANNEL ASSIGNMENT:1) M1 :- MOTOR 1 (CW) 2) M2 :- MOTOR 2 (CCW) 3) M3 :- MOTOR 3 (CW) 4) M4 :- MOTOR 4 (CCW) PLEASE REFER TO THE DIAGRAM BELOW TO UNDESTAND IT AND MOTOR DIRECTION:- Om sree sainathayanamaha GAINS TUNING:The gains of the my copter board can be tuned by adjusting the three potentiometers , the BLUE LED seen beside the potentiometers shows the Kp gains adjusted on the specific potentiometer for ROLL , PITCH and YAW. Please refer to the picture below to better understand the tuning , also you can visit our resource centre on http://www.muav.in/?page_id=23380 REFER TO mycopter gains tuning video to better understand the gains tuning . TUNING THE ROLL KP GAIN:Turn the pot(potentiometer) number 1 (ROLL POT) by 3 turns to enable the pot tuning on the board . this is indicated by the blinking of the BLUE LED (LED L1 REFER TO SCHEMATIC ON FIRST PAGE) . Count the number of blinks in one cycle of the blinking of the INDICATIVE LED , the number of times the led blinks indicates the natural number of the Kp gain of the ROLL axis of the quad rotor board. Om sree sainathayanamaha EXAMPLE OF LED BLINK SEQUENCE :EG1:BLINK…BLINK…BLINK…DELAY FOR 4 SECONDS.(ie; 3 blinks of led) ROLL gain(Kp) : 3 division The above shows three blinks then FOLLOWED BY a delay of 4 seconds. This indicates the gains set on the ROLL axis is 3. EG2:BLINK…BLINK…BLINK…BLINK…BLINK..DELAY FOR 4 SECONDS. (ie; 5 blinks of led) ROLL gain(Kp) : 5 division The above shows five blinks FOLLOWED BY a delay of 4 seconds. This indicates the gains set on the ROLL axis is 5. EG3:4 BLINKS OF LED MEANS GAIN = 4. 5 BLINKS OF LED MEANS GAIN = 5. 6 BLINKS OF LED MEANS GAIN = 6. ----------------------------------------------------------------------------------------------------------------MIN VALUE OF GAIN = 1 DIV MAX VALUE OF GAIN= 10 DIV TUNING THE PITCH KP GAIN:Turn the pot(potentiometer) number 2(PITCH POT) by 3 turns to enable the pot tuning on the board . this is indicated by the blinking of the BLUE LED(LED L1 REFER TO SCHEMATIC ON FIRST PAGE) . Count the number of blinks in one cycle of the blinking of the INDICATIVE LED , the number of times the led blinks indicates the natural number of the Kp gain of the ROLL axis of the quad rotor board. EXAMPLE OF LED BLINK SEQUENCE :EG1:BLINK…BLINK…BLINK…DELAY FOR 4 SECONDS.(ie; 3 blinks of the led) PITCH gain(Kp) : 3 The above shows three blinks FOLLOWED BY a delay of 4 seconds. This indicates the gains set on the PITCH axis is 3. EG2:BLINK…BLINK…BLINK…BLINK…BLINK..DELAY FOR 4 SECONDS(ie; 5 blinks of the led) PITCH gain(Kp) : 5 The above shows five blinks FOLLOWED BY a delay of 4 seconds. This indicates the gains set on the PITCH axis is 5. Om sree sainathayanamaha EG3:4 BLINKS OF LED MEANS GAIN = 4. 5 BLINKS OF LED MEANS GAIN = 5. 6 BLINKS OF LED MEANS GAIN = 6. MIN VALUE OF GAIN = 1 DIV MAX VALUE OF GAIN= 10 DIV TUNING THE YAW KP GAIN:Turn the pot(potentiometer) number 3 (YAW POT) by 3 turns to enable the pot tuning on the board . this is indicated by the blinking of the BLUE LED(LED L1 REFER TO SCHEMATIC ON FIRST PAGE) . Count the number of blinks in one cycle of the blinking of the LED , the number of times the led blinks indicates the( Kp gain of the YAW axis/40 of the quad rotor board. CALCULATION OF GAIN KP FOR YAW AXIS= 40*NO_OF_BLINKS_OF_LED EXAMPLE OF LED BLINK SEQUENCE :EG1:BLINK…BLINK…BLINK…DELAY FOR 4 SECONDS.(ie; 3 blinks of the led) NO_OF_BLINKS_OF_LED = 3 (substitute in above equation) Kp gain yaw axis:- 40*3 = 120 KP GAINS: 160 The above shows three blinks FOLLOWED BY a delay of 4 seconds EG2:BLINK…BLINK…BLINK…BLINK…BLINK..DELAY FOR 4 SECONDS(ie; 5 blinks of the led) NO_OF_BLINKS_OF_LED = 5 (substitute in above equation) Kp gain yaw axis:- 40*5 = 200 KP GAINS: 200 The above shows five blinks FOLLOWED BY a delay of 4 seconds. MIN VALUE OF GAIN = 100 DIV MAX VALUE OF GAIN = 400 DIV Om sree sainathayanamaha MOUNTING THE BOARD : Please refer to the diagram below :THE BOARD SHOULD BE FITTED ON A PROPER DAMPNER FOR PERFECT FLIGHT WITHOUT OSCILLATIONS . ARMING , TESTING AND FIRST FLIGHT:Arming the quad rotor:On start up the GREEN (LED : L2 REFER TO SCHEMATIC) colour led on the A&B Mini will blink for 1 second after which the BLUE LED (LED : L1 REFER TO SCHEMATIC) will blink for one second. After a few seconds the GREEN colour led (LED : L2) on the A&B Mini will start blinking at a frequency of 1Hz , THIS MEANS THE STARTUP ROUTINES ARE COMPLETED AND THE BOARD IS READY TO USE. Next arm the board by keeping all the controls on the transmitter in the center position and keeping the throttle stick in the lowest position, move the rudder to the right side (extreme ) the GREEN colour led (LED : L2) on the A&B Mini will start blinking at 3Hz frequency this means the board has been armed. Note:- after landing the quadrotor , the board will automatically disarm and the GREEN colour led (LED : L2) on the A&B Mini will reduce to a blink frequency of 1Hz . NOTE:- NONE OF THE CHANNELS ON THE TRANSMITTER SHOULD BE REVERSE (FOR HITEC , FUTABA AND JR) Please refer to picture below:- Om sree sainathayanamaha Testing the quad rotor and flying:Arm the quad rotor and take it in your hand , give half throttle and tilt the quad rotor about X axis(roll) and Y axis (pitch) the board should give a control so as to oppose this movement , if the control is there but is too less then increase the gain . Now fly the quad rotor if the quad oscillates with large amplitudes then increase the gain , if the oscillations are of small amplitudes or deviation but high frequency , like its vibrating then the gain is too high , reduce the gain .
