How to Make an RC Flying Micro Robot Yourself
I wish I could fly. (Retro Robot & Son image by Infs from

The average person is not an expert in robotics or artificial intelligence. However, making your own flying RC robot is not as difficult as it may seem. RC (radio controlled) toys are a lot of fun for people of all ages whether they enjoy recreating battles at sea with RC battleships or racing RC cars and planes. You can be sure though, you will stand out in the local park when your flying robot is racing through the sky.

Skill level:

Things you need

  • Robot shaped airframe
  • Sub-micro servo and propeller
  • 1-channel RC controller and antenna
  • Low voltage battery
  • Soldering iron
  • 1-channel variable output transmitter

  1. 1

    Build a frame out of plastic, balsa wood or any other light and strong material to resemble the desired shape of your robot. Make sure there is a main hollow section, perhaps in the head and the abdomen if the robot is to resemble a human, that will house the servos, antenna and battery.

  2. 2

    Install the sub-micro servo in the head of your robot so the propeller shaft is exposed through the top of the robot. Connect the propeller and ensure that it is not obstructed in any way when it rotates.

  3. 3

    Install the RC circuit and antenna in the body of the robot so that it does not interfere in any way with the operation of the sub-micro servo and the propeller. Use the soldering iron to solder the output leads from the RC circuit to the inputs on the motor. Secure the wires so that they do not interfere with the operation of the propeller.

  4. 4

    Install the battery below the RC circuit and antenna in the body of the robot. Solder the battery connections to the RC circuit and test operation by connecting and disconnecting the battery before securely attaching it.

  5. 5

    Leave the solder to cool for a few hours until all connections are fastened and secure. Paint or decorate the robot as desired.

Tips and warnings

  • All the components required can be found at most electronics and hardware stores.
  • Ensure the propeller is set to spin in the appropriate direction. If it does not, reverse the power leads from the RC circuit to the motor.
  • Test flights should never fly higher than a few inches before it is certain that the robot is operating as it should.
