Hi, I'm looking for advice for the new antweight robot I'm building. The robot itself is largely built, however, I can't seem to get it to drive right.
I have about a few hours worth of practice under my belt now (never competed in a fight yet, this is my first robot) and I still struggle with driving it. I use tank steering on my robot, which makes it harder to drive, but gives you more control if you master it.
It seems to the problem is that the robot refuses to go in a straight line, and doesn't make much grip on my kitchen floor where I test it.
The event I'm going to has a steel floor which I hope has more grip. Is there anyway I can give my wheels more grip before then? Do I need to replace the wheels?
It's also quite hard to know whether the robot is hard to drive or if I'm just bad at driving. Is there any general advice you can give about making the robot easier to drive, or do I just need to keep practicing?
Edit: I think I figured out the root of the issue. The right wheel always moves faster that the left one, regardless of how far forward I move the left joystick. I think the reason is because the transmitter i use (fs-i4) was designed for model helicopters. It can be used for a combat robot if you do mixed steering. The problem is that as soon as you switch to tank steering one wheel becomes more powerful that the other. Is there any way to make the two wheels go the same speed using tank steering on an fs-i4, or do I have to switch back to mixed steering?
