VexIQ Engineering Curriculum

Hello

Recently I’ve used the VexIQ programming Currulum , it’s a good one that focus on programming & configuration issues for the VexIQ (using RobotC P.L,)
so ,I want to ask if some one knows a good curriculum that focus on engineering issues for VexIQ
like building techniques , gear ratio issues, lifting mechanisms , object manipulation , and more

as i can see in the VexIQ Curriculum, they talk about some engineering topics , but with limited information and without any applied tasks or activities

I would be thankful for any help

Best Regards
