Remote Controlled Rocket Launcher

We’ve made a number of different versions of the mobile rocket launcher, and all of them have been fun. The version above is using the a PI 1 with a PiFace Digital module for the motor controls and a wireless keyboard for the controls.

The version shown below is using a PI 3, with an ExploreHAT Pro for the motor controls and a Python Web Server program for the controls. By using some simplified HTML tagging we were able to use an old PSP as a remote interface console.

Rocket Launcher Sample Code

We found the rocket launcher in a sale bin, but they call be purchased at: http://dreamcheeky.com/thunder-missile-launcher. The rocket launcher comes with it’s own Windows based program.

Below is some Python code that will control the rockets launchers turret and fire a missile. Based on this sample code you should be able to make some cool projects. A couple of notes from our testing:

  • you need to manually stop the turret motion once you start it. So you need to set your own wait time
  • you need 3-4 seconds between each missile firing. It might be a coincident but we damaged our first rocket launcher trying to issue fast firing commands.
