Test 1 Automation and Robotics 24/25 Sem2

Your group wants to program a motor to drive forward for 2 seconds, stop for 1 second and then drive in the opposite direction for 4 seconds and stop. You create the following code. Will this code execute as you intended?

• No, they should change the first WAIT block to "1" second.

• Yes, this programming code meets all the requirements.

• Yes, but they should change the last DRIVE block to "2" seconds.

• No, they should change the first DRIVE block to "reverse".

Which of the following statements below is true when creating a flowchart for an algorithm? Select all that apply.

• The ending point is shown by a triangle.

• The beginning point is shown by a rectangle.

• A command is represented by a rectangle.

• The arrows show the flow of steps

Drew, Anaya, and Olivia are working together on a gear train. They want the output speed to be faster than the input speed. How should they assemble the gears to achieve this result?

• The driving gear needs to be larger than the driven gear.

• The driving gear and driven gear need to be the same size.

• The output gear needs to be larger than the input gear.

• The driven gear needs to be larger than the driving gear.

You have been asked by a company to design a prototype for a propeller for their new drone. They want it to spin at a speed of at least 400 rpm. You are provided with the following materials: Gears in a variety of sizes A motor that spins at 200 rpm Describe the gear train that will meet the requirements.

• The gear ratio of the driving gear and driven gear would be 1:1.

• There are 36 teeth on the input gear and 18 teeth on the output gear.

• The number of rotations of the driving gear equals 5 and the number of rotations of the driven gear equals 1.

• There are 18 teeth on the driving gear and 36 teeth on the driven gear.
