Welcome to the forums!
First off, Spin Up is a VRC game, not a Vex IQ game. This is the IQ section of the forum, so next time, please post in the correct location.
As for your question, this is for you to research. There are plenty of threads already that discuss this topic, such as Best Chassis for Spin Up, and other threads. I’ll tell you that overall, Mecanums can strafe but they are generally slower and easier to push around than Tank Drives, but you need to test or research the topic to decide for yourself. It will also look great in your notebook.
People here will help you with specific issues, but they won’t just give you a robot design or answers to any problem. If you have an issue with your robot, such as motors overheating or lots of friction, then feel free to ask a question in the correct location, but don’t be lazy and expect people to give you all the answers.
@DRow please move this thread or close it.
