Sorry for the OT, but since we are discussing wild lander designs...
I knew it was proposed but never thought someone actually built a mockup.
Notice that there seems to be a rope to help climbing out of the hatch.

. They move forward/back ok. rotation may need some work. And side to side does. I know why because the heading isn't calculated into the equation.
I can share the code for the guys if someone want to take a look
