FORAY - Blimp can recognize and move toward a green ball using color detection

Zhaoliang Zheng foray

Demo: Blimp can recognize and move toward a green ball using color detection（the current blimp setup)

  • Blimp is capable of seeking the ball by rotating itself
  • Blimp is capable of moving toward an identified green ball
  • Blimp is trying to capture the green ball using the capture basket

Under some conditions, it can catch the green ball:

Discussion:

  • Detection range:
    • Right now the maximum range of using color detection algorithm is about 3.7 meters, it's not good enough.
    • We can improve it by tunning the parameters of color detection bounding box
    • We need to improve its detection range by using machine learning algorithm
  • Vertical capability:
    • The vertical motion capability is too weak now, cannot follow the green ball very well
    • We will make a new design that has 2 motors for the vertical movement
  • Camera:
    • The camera is now attached to the gondola, so it will miss the target sometimes
    • We need to move the camera to the nose of the blimp and we think it will help in capturing the green balloon
