this robot is the product of this experiment
is works great
the cost 4$
So what did you end up doing to soften the treads up? You said the treads cost you two dollars, for what was the other two an expense? This may be a basic question, but what did you do to get the square vex axles to fit the circular hole in the center of those hubs? Finally, what are you using for boogie wheels?
It looks good, and looks like it would have a significant amount more traction than the Vex treads.
i didn’t soften them i found more i’m using two more drive wheels from the first caterpillars
