More specifically, how many wheels you have on the ground, how many of them are powered, are any of them “dropped”, and “wide” configuration vs. “narrow” configuration are good items to include when asking a question like this.
We’ve used a similar design (IFI High Traction instead of Plaction) for years with excellent results. In our early days we used 4-wheel skid steering as you initially described, and went through batteries in just under 2 minutes. :ahh:
Expect high currents in the CIMs and possible low battery voltage at the end of the match. Please try the robot on carpet before you make a final decision. If you don’t have a practice field take the robot into the library, theater or any place with a lot of carpet and practice turning.
I can say that the 2 omnis/2traction 4WD tank steering is actually really nice. We ran it in 08 and it handled perfectly and was super simple.
Although, we had about 75% of our weight on the traction wheels, where more likely teams this year will be fairly evenly spread out.
I’m a fan of the 2 traction / 2 omni offset myself. You know,
T — O
O — T
2 traction 2 omni makes it fairly easy to have your robot spun by an opponent, which is why I personally prefer a high traction drop center (no omni) drive in most “normal” FRC applications. Powered omnis do work more than fine, though. This year isn’t very normal.
