About this project


________________

Hi, First off all Please subscribe to my youtube channel.

This is the simplest Arduino robot. The name of this Arduino robot is Otto Robot. The beginners can build it with simple steps. All codes and library is given on my github page.

Let's begin this cut little arduino project.

________________

Step 1: Requirements

  • Robot Body, you can buy it online or you can print yourself, download stl file from here.
  • Four SG90 servos
  • Arduino nano
  • Arduino nano programing cable.
  • expansion shield for arduino nano.
  • Ultrasonic module.
  • Gel based super glue.
  • 134N3P charging and booster module.
  • 3.7V 1000mAh battery.
  • Screw driver and screws.
  • Servo Top that comes with servo.
  • On / off push switch.
  • Some female to female wire.

Step 2: Mount Leg Servo

  • Mount two servo as shown in image.
  • Screw it tightly.

Step 3: Mount Servo Top on Leg

  • Cut the plastic top comes with servo.
  • glue it in side the leg as shown in image.

Step 4: Pass Feet Servo Wire

  • Pass servo wire from hole in leg
  • Pass the same wire from the bottom part of robot.

Step 5: Set Servo 90 Degree Connections

  • mount legs on leg servo.
  • take Expansion shield and insert arduino nano.
  • Connect both leg servo at 9th and 10th pin.
  • make sure yellow wire facing arduino nano.

Step 6: Upload the Code to Set 90 Degree

  • Open servo_pos_set code, you can download it from here.
  • Connect your arduino and select correct Board and correct port.
  • Upload the code and servo will move at 90 degree.
  • Remove legs from servo and insert it in vertical position as shown in image.

Dowload the code :- https://github.com/vishalsoniindia/Arduino_Otto_Ro...

________

Step 7: Screw the Legs

  • Take a screw driver attach magnet with it so screw can stick with it.
  • Hold the leg and screw it.

Step 8: Mount Feet Servos

  • Pull the feet servo wire as shown in image.
  • Insert feet servo in legs as shown in image.
  • Screw the feet servo on leg.

Step 9: Set It at 90 Degree and Mount Feets

  • Connect feet servo at 9th and 10th pin.
  • Connect arduino with pc no need to upload code again.
  • servo move to 90 degree now mount servo top in vertical position and screw them.
  • mount feet, first put feet on servo and with little presser push feet inside.
  • Do it with both.

Step 10: 134N3P Connections

  • Remove USB from 134N3P module.
  • Connect positive of battery at B+.
  • Connect negative of battery at B-.
  • Connect wires on Gnd and Vcc.
  • Vcc wire go through a switch.

Step 11: Connect Battery With Arduino

  • Remove DC jack from Expansion shield.
  • Connect Gnd wire at Gnd of DC jack as shown in image.
  • Vcc go through switch and then connect it on Vin pin.
  • Test the switch working properly.

Step 12: Assamble Top Part of Robot

  • Mount ultrasonic as shown in image.
  • Mount expansion shield as shown in image and screw it.
  • Fix the 134N3P module at place of dc jack with hot glue as shown in image.

Step 13: Circuit Connection of Otto Robot

Left Leg servo ---------------> 8th pin

Right Leg servo ---------------> 9th pin

Left Feet servo ---------------> 10th pin

Right Feet servo ---------------> 11th pin

Ultrasonic Connections

Vcc ------------------> +5v

Gnd ------------------> Gnd

Trig -------------------> 2nd Pin

Eco -------------------> 3rd Pin

Step 14: Close the Robot

  • Glue the switch inside as shown in image.
  • Use pen riffle for Switch Cap.
  • Insert all things inside robot and close it.

Step 15: Install Library

  • Open downloaded folder or you can download from link below.
  • Go to the Otto_robot_code >> library >>
  • Copy Otto_Robot_Lib folder.
  • Go to the Documents >> Arduino >> libraries >>
  • Paste the folder here.

Download the folder :- https://github.com/vishalsoniindia/Arduino_Otto_Ro...

Step 16: Upload the Code

  • Come back to the downloaded folder.
  • Here You can upload any code, Let's open Otto_object_avoid code.
  • Connect robot with PC and make sure the Board and port is correct.
  • Put your robot upside down and upload the code.
  • your robot start running.

Step 17: Done

Whooooo.................

Now put hand in the front of robot it will stop go back turn littlie bit and run again.
