Are teams allowed to use previously built robots or parts from prior seasons?

Teams are permitted to use previously built robots or parts from prior seasons, but any modifications made to those parts or robots must comply with the current season's rules. This allows teams to leverage previous designs and innovations while ensuring that all components meet the latest regulatory standards outlined for the current competition. By allowing modifications within the framework of updated rules, teams can improve their designs based on past experiences and adapt to new challenges, ultimately fostering creativity and innovation in their approach. This balance encourages teams to build on their previous knowledge while adhering to the evolving nature of the competition.
