no you defintly could do that. for example. push the stick to the top right while rotating the stick counterclockwise. well a better way to say iot would be to rotate the stick counterclockwise with B as the axis. then according to
.........+...+
....A.../.....\...B
.......-........-
.......+........+
....C..\...../...D
.......-.....-
C would be at -, A towards -. D towards+.
right? with B still at neutral. so then the robot would be doing the same thing.
rotating counterclockwise with B at the axis.
so now comes the place where a little more imagination is req'd.
now move the stick the same way as before(b as the axis counterclockwise) but now move the axis of rotation a little closer to the A stick. so A-,C-,D+ but B is only slightly towards +.
guess what? the robot does the same thing. the axis it is rotating at is a little above B but a littel towards A too. and it is shuffling towards NE too. i think. i confused myself slightly. forgive me. its a friday night. but i just wanted to prove you COULD translate and rotate at the same time. NO problem. just a matter of driver getting used to.
