Task #6 – Tekrocks Bridge

Mission:

You are an employee of Terrific Teddy’s Engineering Company. Teddy has requested that you develop a solution to the following problem. The Techville Railroad Company would like to install a bridge to cross the Tekrocks River. Teddy has researched many possible designs and has decided to install a turntable bridge. You must design, create, and program a working model of this turntable bridge. The bridge will allow trains to cross the river when it is in the closed position and will allow boats to pass when it is in the open position.

Guidelines:

#1 The bridge should be rotated by a motor. The rotational motion of this bridge should be slow and controlled.

#2 You have the job of creating a program that will control this bridge. The bridge should start in the closed position (to allow the train to pass). When a limitSwitch is pressed, the bridge should rotate until it reaches the open position. When the button is pressed a second time, the bridge should rotate back to the closed position. The bridge should not rotate more than 90 degrees in any direction. Open the PLTW Template and Save As Bridge to your directory.
