Time for a challenge

Challenge #1

One more way to make turns is by simply running both motors at different speeds. By doing so, your robot will steer just like your car, instead of turning sharp at that very point. This technique can be useful when you want to make smooth, long turns of form shapes such as an arc or a circle. Either draw a big circle or find a big enough circular object in your home and try to code your rover to move around it using this technique.

Challenge #2

Can you build a seesaw using the external motor and LEGO parts in your BOOST kit? A seesaw is a common example of a simple machine lever.
