Hi there STeven,
Me again :)
I just wanted to point out that in the attached .robo file, my SRV_1b's camera isn't really pointing straight down, so I decided to crop the top part of the image off.
Now, following the line following tutorial you gave ages ago, I tried to add the COG pipeline onto the end after cropping and it goes all weird as you may see if you give it a try.
On 'watch variables I get COG X to be:
86 ( for the COG being on the left) 144 ( " " middle) 188 ( " " right)
So, this makes a bit of sense despite '86' should really correspond to '0' I guess.
I think the problem lies with cropping and therefore seems to be some stretching of the COG line.
Hopefully you can see what is going wrong
Best regards
