Add weight for better traction

Add weight for better traction

It has been my experience that the robot frequently gets stuck spinning its tracks. I have installed the traction studs and it did help a little, but it still is frequently losing traction.

When it does this I have found that adding a bit more weight helps to give it the additional traction needed.

I am wondering if it would be possible for Yarbo to create an optional weight attachment that be mounted to the top of the main robot body? Even better would be if this additional weight could consist of additional batteries to increase runtime.
