Re: 3-wheeled robots

Here's a problem that I don't believe anyone has mentioned thus far.
The first and last robot we used caster wheels on (2006) was highly unstable. The problem was that after rounding a turn the rear caster wheels would keep right on going causing our robot to fishtail. It cause numerous headaches esp. during autonomous.

In a low friction environment the fishtailing due to a caster wheel will be exaggerated and might make your robot undrivable depending on weight distribution.
