Demo: Blimp recognize and move toward an April tag

  • [x] Camera is capable of identifying the April tags below the goal
  • [x] Blimp is capable of moving toward an identified goal
  • [x] Test the range and performance of this capability
  • [ ] Blimp can conduct rotation and vertical motion using the April tag as feedback


  • The April tag detection window is not as the same size as previous green ball detection. Based on the experiment and the preview from the OpenMV IDE, I think this is smaller(160 * 120) than the previous one (320,240).
  • Since the April tag is smaller than the previous one, it's easy to get out of the range of view angle.
  • There are still some bugs in the code.
