Let's change the code so that your robot moves when the **UP** button is pressed.
Add a ``||brick:on button enter||`` block and move the ``||motors:steer motors||`` under it.
Add an ``||brick:on button up||`` block and move ``||motors:steer motors||`` inside of it.

When the motors are done turning, the robot keeps on moving for a short distance.
Turn on the **brakes**, so that your robot stops immediately.
