本帖最后由 2119124 于 2012-6-8 10:46 编辑 Ollie is an open source blimp-based autonomous and ambient robot that dwells in human habitats. Ollie is observant, often flying in a manner suggesting curiosity for the world around him. Ollie reacts to voices by excitedly flapping his wings, communicating his friendliness and eagerness to be noticed. Ollie wants to know about humans and yearns for their attention.Ollie has an Arduino brain, wings to fly and a microphone to listen. In this instructable I will teach you how to make Ollie so you can meet him too. Please contribute suggestions, experiments, tweaks, hacks and discoveries of your own process here and comment on www.meandollie.com. The main parts needed are :1 Arduino Pro Mini 328 – 5V/16 Mhz1 FTDI cable or breakout board to charge Arduino Pro Mini1 Electret Microphone1 Polymer Lithium Ion Battery 850 – 900 mAh2 Blue Arrow 3.6 Gram Micro Servos1 36″ Mylar balloon envelope 1 30 guage wire/ wire-wrapping wire in 2-3 colors1 LED1 Sheet of Mylar or foil for wings1 Spool of sculpture wire for wings1 Helium tank or access to a party store1 Switch1 3.9 KΩ resistor1 4.7 KΩ resistorAdditional itemsArduino Uno or other (for testing)Breadboard22 or 24 guage wireLightweight tapeSmall weighing scaleSoldering iron and solderQuick-setting EpoxyGlue gunPlaydoh or claySmall cupsCutterWire stripperWire wrapping toolMaking the Wings Bend sculpture wire to create 2 identical wing shapes. Try toconserve amount of wire used to minimize weight. Use epoxy to secure theends.Attach servo accessory to the ends of the wings keeping check oforientation and secure with epoxy. Secure with small pieces of tape ifnecessary.Cut out identical pieces of Mylar or foil and attach to wire shapesusing a glue gun. Leave the foil loose when attaching so it takes ahemispherical shape when wing is flapped.Attach wings to the servo.Wire up the servos using wire-wrapping wire.Plug the control wires from the servos to digital pins 2 and 4 andconnect to 5V power and ground on a breadboard and/or Arduino Uno (for testing)Upload a basic servo program to check wiring making sure that both wings exhibit identical motion.If wings are not moving check continuity in circuit, secureconnections and try again. If circuit works, disconnect and preparewiring for Arduino Mini Pro.Insert servos through 2 small identical plastic cups and glue tosecure in place. Make sure wings move without any obstructions. Cups areuseful in attaching wings to the balloon and hiding wires.Mark points on the empty 36″ blimp envelope where wings will bemounted. Points should be in exactly opposite on the balloon surface andprovide balance to the blimp.Cover the cups with Mylar foil using glue gun.Fill up 36″ Mylar envelope with Helium.Attach servo cups to the balloon using small pieces of tape. Let wires hang loose.Cover the tape with pieces of Mylar or foil.Adding Microphone and LEDPower the Electret mic through Arduino Uno as shown in circuitdiagram using 2 resistors of 3.9Kohm and 4.7Kohm. Control wire should beplugged into analog pin 2 of Arduino.Connect LED to digital pin 13 on Arduino Uno.Make sure all connections are secure.Resistors are used to increase the amplification of the signal received from the Electret mic and should be wired correctly.Run this simple program to make sure input is being received. LEDwill light up whenever a certain threshold of volume is reached. Thisthreshold should be set to a normal or loud talking volume.int buffer = 0;//Sound variablesint potPin = 1; // select the input pin for sound sensorint ledPin = 13;// select the pin for the LEDint soundVal = 0;void setup(){pinMode(ledPin, OUTPUT);// declare the ledPin as an OUTPUTSerial.begin(9600);// open the serial port at 9600 bps:}void loop(){ //Sound soundVal = analogRead(potPin); //Serial.println("Listening............"); if( soundVal>1020 ){Serial.println("VERY LOUD!");digitalWrite(ledPin,HIGH);} else if (soundVal750){if (buffer == 0){Serial.println(soundVal);buffer = 15;digitalWrite(ledPin,HIGH);}else{buffer--;} } else{ digitalWrite(ledPin,LOW);}}If the circuit is not working play with the values in the program and make sure resistors are wired correctly.If the circuit works, wire everything up according to the circuitdiagram. Attach toggle switch and LiPo battery to the circuit. Solderall the wires directly to each other and secure with hot glue.Upload the final Arduino sketch given below to the Pro Mini using FTDI cable or breakout board.#include SoftwareServo myservo;// create servo object to control a servoSoftwareServo myservo2;int goUp = 0;int val = 0;int wait = 0;int flyFor = 0;long flapTime = 0;int angleMin = 0;int angleMax = 120;int upSpeed = 20;int downSpeed = 1;int buffer = 0;//Sound variablesint potPin = 1; // select the input pin for sound sensorint ledPin = 13;// select the pin for the LEDint soundVal = 0;void setup(){pinMode(ledPin, OUTPUT);// declare the ledPin as an OUTPUTmyservo.attach(2);// attaches the servo on pin 2myservo2.attach(4);Serial.begin(9600);// open the serial port at 9600 bps:}void loop(){// Servoif (flyFor < flapTime){ if (wait == 5){if (val < angleMin){goUp = 1;digitalWrite(ledPin,HIGH);}else if (val >angleMax){goUp = 0;digitalWrite(ledPin,LOW);}if (goUp == 0){val-=upSpeed;}else {val+=downSpeed;} } wait++; if (wait > 200)wait = 0; myservo.write(val);// sets the servo position according to the scaled value myservo2.write(120-val); SoftwareServo::refresh(); flyFor++;}else{//Sound soundVal = analogRead(potPin); Serial.println("Listening............"); if( soundVal>1020 ){Serial.println("FREEAK OUT!");upSpeed = 15;downSpeed = 15;angleMax = 45;angleMin = 10;flapTime = 6000;} else if (soundVal750){if (buffer == 0){Serial.println(soundVal);upSpeed = random (1, 20); //1 to 30downSpeed = random (1, 30);// 1 to 30angleMax = random (110, 120);angleMin = random (30, 45);flapTime = 10000 + random (5000 , 10000);flyFor = 0;buffer = 15;}else{buffer--;} }}}Solder connections to the Arduino Pro Mini very carefully according to the circuit diagram. Attach circuit to bottom of balloon using small amount of foil or tape.At this point circuit will be light enough to be lifted by theballoon or just the right weight to keep it in equilibrium. Adjust with a small amount of clay if circuit is too light. Ollie is ready to fly. Turn the switch on so Arduino Pro Mini ispowered with the battery. Ollie will flap his wings whenever he hearsyou talk or a loud sound is made. Ollie will randomly burst into flightand bring happiness and joy in the life of many.
