This week I learned about differential steering an car-type steering. Here are some differences and likenesses between the two.
Both of the steering types are non-holonomic. This means that the base has to turn in order for the whole thing to turn. Differential steering is very agile. To go straight both motors will need to go the same speed and to turn one motor will have to go faster. If you want to go in a circle the motors will both go in the opposite direction.
Car-type you have the front two wheels turn and the back are still. It is a lot easier to move in a straight line compared to differential steering.
This is just a little bit of the things I learned in science this week.
