Center Drop on 6WD 1/8 or 1/16

[David Guzman]

Some of the things to consider are:

-Rubber material and how much it will compress.

-Type of wheel. Might not need drop if using omnis at one of the ends.

-Distance between centers of the wheels. The further out the more difference there is in the "rocking" of the robot. (As pointed out, less rocky as you spread out the wheel base)

-Frame deflections, if any. Not much of a problem if your have a nice and rigid frame.

From my experience I suggest you go with 1/8" drop on the center wheel. I have also used 3/16" in the past. I don't think 1/16" is enough in my opinion, and depending on your specific set up, you might encounter difficulty turning.

Keep in mind that the center drop mainly affects how much your robot rocks back and forth. While driving, depending on your mass distribution, you will always be riding on the front or back 4 wheels.
