Add Motion controls (#1363)
* Add motion controls

Apply suggestions from code review

Co-authored-by: Ac_K <Acoustik666@gmail.com>

* cleanup

* add reference orientation and derive relative orientation from it

* cleanup

* remove unused variable and strange file

* Review_2.

* change GetInput to TryGetInput

* Review_3.
