Math with XYZWPR variables in Karel?

VAR
pos1, pos2,pos3 : XYZWPR 
pos4: POSITION

BEGIN
 pos4 = pos2 : INV(pos1)
 pos3 = pos4

END

The robot in most times does automatic conversions between XYZWPR and POSITION.

Hi,

Is it possible to access fields of POSITION data just like XYZWPR?

I have initialized

uframe, utool : POSITION

and gett the following error.

What is the correct syntax to access fields of this position variable? This works for an XYZWPR

POSITION.LOCATION.X

POSITION.LOCATION.X

Thanks TitusLepic

Hi,

Just to confirm,

Does the orient field contain the roll, pitch, and yaw values? and Location field just contains XYZ values?

I am having the following error now

No. This is a matrix representation of the point. The location vector just contains XYZ values, but if you're looking for WPR representation you'll need to convert your position into XYZWPREXT. I believe that karel automatically converts between the data types, so you should be able to declare a new variable as XYZWPREXT and then assign it your position value. Something like this:

uframe : position

uframe2 : XYZWPREXT

.

.

uframe2 = uframe

write(uframe2.x,cr)

I haven't tested this but from what I've read it should work.

Thanks, I did similar but i use INV() built-in.
