I’ve already downloaded the latest docker:
Status: Downloaded newer image for jderobot/robotics-academy:4.5.13

Hi @dduro2020,

please do not use RADI 4.5.X, they are the next generation RADIs and currently they only work with RoboticsAcademy. Just use the last RADI 4.4.X and last 3.4.X when solving the exercises from Unibotics.

Ok, I’ll try, thanks!!
