I tested it and it works perfectly well I only have 1 advice to tell you: When going backwards I think that the legs would be better to look at the backward direction while the cabin looks in front. (I hope you get what I mean). Lastly is there any possibility you could make it in godot 4.x because I started godot from 4.1 v and I have no idea about 3.x. As for the gaming I want to make is just an idea and I never get to finish my ideas xD. If you want you can check my YT channel to see some "ideas" of mine:
Thank you so much man I've been searching for ages for an animated mech(cause I am not of a blender guy) and I found this ,WHICH, moreover is especially made for godot. I'll let you know if it came in handy and what possibly could be fixed-improved.
