Comments.Text: @SanderDeDycker yes, size constraints are around 1 sq inch for a quadric plate that should be able to tilt around 10 degrees in each direction (for a total of around 20 degrees in x tilt direction and the same for y, if that makes sense)

  (Asked by: username_0 on 2024-06-02)
  
  I would like to attach a sensor to a plate, and tilt that plate slightly in the XY direction respectively, without moving the plate itself.
  
  Similar to this [(force feedback joystick concept) like this one](https://www.youtube.com/watch?v=R_AvYSDZBCI):

  But not for force feedback, just for using two servos to adjust the plate's left/right (X) and front/back (Y) direction.
