And that is the reason I quoted the @ChrisR246 quote, since they were the first to mention an “H” drive. And yes an “H” drive in IQ should be possible (again im not in IQ so I dont know the exact challenges one might encounter while using an “H” drive in IQ). If you wanted to use only 3 motors (which is a goal of a kiwi drive, to provide holonomic movement with only 3 motors) You could…
Option 1
Gear/chain (idk the strength of IQ chain, or the average stress the weight of a robot puts on the drive etc., so it might not be pheasible to use chain on a drive) the side wheels together so turning would still be around the center wheel.
Option 2
Only have 2 powered side wheels, but when turning also spin the center wheel so the side wheel motors do not encounter unnecessary resistance when turning the robot that would either limit or destroy a robots turning ability.
But if you really wanted to waste your motors in IQ you could use 5 motors and directly gear all the wheels you masochist(please take this as a joke )
According to one of my coaches: While it is possible to build a kiwi drive, it is extremely difficult for a VEX IQ team to do so. Although there is a build manual online, the product is way too small to be of any use: nothing can be mounted.
Furthermore, even if an IQ team managed to build a functional, mountable kiwi drive, chances are they couldn’t program it. If a team managed to do so, one would almost be sure that certain adults were meddling in their team…
Actually, I reffed and my friend judged a vex IQ team that mounted a dr4b to a kiwi drive, programmed it themselves, and were very successful. And no, adults were not meddling, my friend actually had a complete conversation about C++ with one of the girls on the team with no adults present.
