Hi y’all,
Last year, my team used the following formula to calculate gimbal angle with mouse input:
pitch += mouse_y * deltaTime * sensitivity
yaw += mouse_x * deltaTime * sensitivity
This worked okay, but definitely wasn’t ideal. This only gives smooth 1:1 motion for an FPV camera mounted in the center of rotation, and is not the case for most RoboMaster robots. It’s akin to having mouse acceleration on in a video game.
If you were to graph all the possible locations for the camera, it would look like a spherical segment or “napkin ring”:
Has anyone tried mapping mouse input to a plane like above, or have any other ways of calculating gimbal angle to feel more “natural?” I’m sort of stumped on this problem.
