Re: Bearing Block Question

This year for a preseason build we had the group of newcomers build a 6 WD kitbot. They followed the model outlined in the Kitbot on Steroids video. This worked surprisingly well. They had it running in less than a day.

We plan to do something similar for the actual season simply because it will get you a working drivetrain in one day.

If you want to stick with 80/20, then you can place a rod in between the transmission and bearing blocks (this fits nicely in the slots and can be zip tied to keep it in). This anchors them relative two each other, which is all that you need. We did this a while ago when we built a small 4wd robot to practice driving against. After several impacts, the blocks had moved about a half inch, but we still could drive because everything was still in place relative to each other.
