I do not have access to robotics academy, it turns out that there is no page
It has been moved to Https://unibotics.org. Check its new webpage
No hurry, but would be convenient if the “Exercise Forum” links were updated.
Thank you for your work, you are the very best!
The link to the forum has already been corrected.
Thanks for the report and sorry for the inconvenience.
Have a good week!
