 Our class tried to make touch-sensor-controlled sweepers that would clear 100 LEGO bricks in 30 seconds. 


 We added a bar to the back of our sweeper so that it would push bricks going in either direction.

    Adding the bar on the back was a great idea–you can clear bricks as you back up as well as when you drive forward. Nice job!
