Hello, so my son (5th grade) has made his schools vex iq team. His school has every part in the world x10. What I would like to be able to do is allow him to do building at home separately to build his knowledge/skill as well without breaking the bank. I know there is no one set build for the competition and the idea is to explore and build, I just want to make sure I have enough base pieces for him to do that. I’ve scored some good deals on the main robot kit (750 piece 228-4444) and the foundation add on, as well as adding omni-wheels and some other sensors.
What I was looking to see is if I need another motor or two, gears, chain/sprockets, smart radios, ect or anything else?
Thanks for the help!
