Hi!
I've built a rover using 4WD chassis but it has a problem with turning.
Going back and forth is working properly but turning is very weak and on some surfaces it's not working at all.
I've connected both right and left wheels so when I want to turn I make left wheels go to one direction and right wheels to opposite direction. It should behave like a tank.
I guess that the problem is in friction but why is this happening? Is it because the wheels are so close together?
I saw videos with similar types of chassis and they are working properly.
Here are images of my chassis:

What are my options?
Thanks,
