Building tutorials

Can anyone recommend tutorials for VEX IQ builds? I know there are builds with instructions but I am looking for lessons on how to build subsystems with a purpose. For example, how do gears help you to build a sling shot mechanism, how to use tread to raise and lower an base vertically… ect. All of my students are new to building.

Best way is to build a few of the robots with instructions and learn from doing. With that experience they will be able to replicate mechanisms they see elsewhere and then ultimately be able to take the pieces they have learned and combine them in their own new design.


Many of the Hero Bots have subsystems with a purpose.
They are worth a look
