Recently I’ve come to the realisation that in building my drivetrains the wheels seem to sort of split when ever i start to put some weight on the base. My wheels seem to diverge from the centre. It makes my robot slower, reduces its traction and even torque making it almost impossible to move sometimes. I see other builds online putting plates on the outside of their wheels to close everything but i don’t know if that is the solution to my problem… Any Help?
Actually, that is preciseley the solution to your problem. Essentially what is happening is your wheel on your drivebase is cantilevered, or only supported from one side, which will basically always warp. However, if for some reason you need to keep the wheels in that configuration, you would need to use a much longer shaft on the wheel and have it have many more internal support points.

The easiest solution and what most people do is put a beam on the other side of the wheel. You support it with standoffs or corner connectors on the front and back and it will fix that issue
Also, do you have a standoff behind this spacer (the black 1x1 pitch piece)? I think that also might be causing the frame to bend.

The issue with your base is you are cantilevering your wheels (only supporting them one one side). I tried this last year and I had wheels fall off and the motors had much more tension on them. Try having the end of the motor shaft into the frame
and supporting the wheel from the other side. Just adust the spacing on the shaft and you will have a good base (trust me, it works!)

Thank You, I’ll try it out soon!
