Introduction: Simple HexaBot With IR Remote TV or MP3

About: Im Eric Dirgahayu , im a robot maker at diy project

do you like robots? want to have one but the robot is so expensive, why not make one? you can still have a robot and even make it yourself, trust me you can make it easily and you don't have to pay a lot because it's really cheap.

Supplies

Step 1: Cutting Acrylic Frame

  • Use this layout for making a frame with 2mm Acrylic
  • Make sure the size is right, don't leave any parts left.

Step 2: Frame Intallation

  • Prepare the Acrylic frame and 6pcs mg90 micro servos, you need a acrylic glue for this step
  • Pic.1 this a leg part, attach the small parts to the legs, make sure the hole at smal part fits the cut area in the leg part, fix it with glue, and install the servo using the bolt on the part that has been made, do the same to the other legs. total is 4 led this is for the four legs that are in the corner.
  • there are 2 more legs in the middle pic.4-5, is just attack the servo in the middle leg using a screw.
  • pic 6-11 is is how you attach the middle leg to the main frame, fix it using a glue.
  • pic 12-14 attach all the legs to the main frame.
  • don't forget before installing the servo, put the horn servo on the holes of the acrylic frame.

Step 3: Hardware Intallation

  • Acrylic Frame is ready with servos added, now you prepare install the harware to the frame, take look to the picture.
  • pic.1 the switch on/off add in a back side body robot. use a glue to pin it.
  • pic.2 Ubec 3A placed close to the on/ow switch
  • pic.3 place the Arduino in the middle of the body, fix it with the screw in the hole provided on the body frame
  • pic.4 open the sticker cover on the back of the mini breadboard and stick it on the back of the arduino
  • pic.5 Plug the ultrasonic pins in the middle of the front of the breadboard
  • pic.6 also plug the IR sensor receiver in the breadboard, make sure the sensor can be seen out
  • pic.7 Also install the battery at the bottom of the robot body, use screws or glue to attach it
  • install the top cover by adding spacers with screw.
  • last pictute is optional, shoes for robot, made from 3d print setting print without support.

Step 4: Wiring

  • look at the pic.1 or open the wiring.pdf for more detail and clear
  • put all the positive servo wires together as well as the negative ones.Plug it into the breadboard which is connected to the arduino Vin pin for the positive cable and the arduino Gnd pin for the negative cable
  • for the servo data pins, we will make 6 servos into 3 data output lines by connecting 2 cables and the servo into one line. the rear front leg data cable to the arduino D7 pin, the right middle leg with the left middle leg to the Arduino D4 pin, the left front leg with the left rear leg to the Arduino D2 pin
  • IR Receiver sensor the Vcc pin to 5V pin arduino, Gdn pin tu Gnd arduino, and the pin S to A0 arduino pin
  • Utrasonic sensor Vcc to 5v arduino pin, Gnd to Gnd Arduino pin, echoo to A3 arduino pin, Trig to A4 arduino pin
  • Battery : positif wire to pin swict on/off continued to input + Ubec , Gnd wire to Gnd input Ubec.
  • Outpu Ubec : vcc wire to pin Vin Arduino , and Gnd to pin Gnd Arduino.
  • Note : servo is at 90 degrees at the position as in the picture

Step 5: Programing

1.Install Arduino IDE if you don't have the software. can be downloaded here 

 https://code.google.com/p/arduino/downloads/detail?name=arduino-1.0.5-windows.execan=2

2.copy the Arduino-IRremote-master file that has been provided and then open the Arduino 

 file on your computer at local disk/programfiles/arduino/libraries Paste the file

 Arduino-IRremote-master.

3.Run the Arduino IDE software, click File open and select the IR_Receiver file that 

 has been provided or simply double-click on the IR_receiver.ino file

4.prepare Arduino uno

5.plug in the T-sop or IR Receiver included in the package. we have given the color on 

 each leg of the T-Sop, red for Vcc, Black for Gnd, and blue or yellow for

 to enter analog pin A0.

6.connect the arduino that has been installed with T-sop and upload the IR_receiver. if successful, 

 open Serial Monitor on Arduino IDE. by clicking on the magnifying glass icon in the right corner

 software, and a new window will appear now press a button from the remote that has been provided, you can use any IR remote such as remote tv, mp3 . 

 if a number or value comes out, it means you have succeeded in the first

 stage.now open the IR_Onggobot.ino file after it appears click the ir_command_codes.h option and 

 a command for the robot action will appear. your task now replaces the value

 XXXXXXX in ir_command_codes.h with the number of each key you selected to perform the command. 

 for example, you select button no.1 to go forward then press the number button 1

 and the serial monitor will display a value for example 12345678 and now open the ir_command_codes.h 

 window where you have entered the number from pressing button one to

 'const long IR_COMMAND_FORWARD_CODES[] = { xxxxxxxxx };'you change xxxx with the value 12345678  

 obtained from serial monitor button no.1 so 'const long IR_COMMAND_FORWARD_CODES[] = { 12345678 };

 and select another button for reverse turn command and others.

7.if everything is filled now, upload ir.kolomonggobot.ino to arduino. when Upload done. 

 means the robot is ready to receive commands from the remote control earlier.

8.Install battery and your robot is ready
