A ball caster is a great way to provide stability to a small robot with a differential drive. The ball does not have any directional bias that would cause the robot to go in unexpected directions unlike a traditional pivoting wheel caster which are better suited to bigger heavier robots (and shopping trolleys).
The kit comes with:
