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: still from the video

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

    Do you want to translate the plate, or do you want to tilt the plate? Commented Jun 2 at 10:26
  • I believe the answer to that would be Tilt. Commented Jun 2 at 10:33

    I immediately had to think of the Lego Ideas 21305 Maze set. It has this kind of setup built into it, with two knobs to control the bi-axial tilt of the upper plate. Commented Jun 2 at 11:08

    Are you working under any size constraints (height, width) ? And how many degrees of tilt would you need in each direction ? Commented Jun 2 at 11:10

    @user3607022 You might wanna read en.wikipedia.org/wiki/Euler_angles#Tait%E2%80%93Bryan_angles and use "roll" and "pitch" instead of "front/back" and "left/right". Commented Jun 3 at 9:25

Check out the instructions (around steps 10-11) of 8855 Prop Plane. This model has a control stick that can tilt around two perpendicular axles:
