Auto Testing

What is a robot?

Controlling a robot involves programming a sequence of steps that can be repeated. Sensors can be used to provide feedback on the robot’s position so the steps are repeated reliably and safely.

Problem Statement

Reliable Auto Testing wants to automate their basic headlight, horn, speed, and reverse gear testing.

Design Briefs

Design and build a robotic car tester that includes:

An on / off switch

A moveable light tester

A test of the tires’ rotation

Build the model shown in the building instructions 9701-3

Attach the following outputs and inputs as shown in the instructions.

Whistle	Port A	Goes off when test is okay
Headlight	Port B
Headlight	Port C
Car Motor	Port D
Rotation Sensor	Port 5	On / Off Switch
Light Sensor	Port 6	Checks if headlights go on
Rotation Sensor	Port 7	Checks the speed and direction of the tires

This addresses the main design criteria to receive a C for your car tester

1. Rotation Sensor 5 is the On / Off switch; use the Wait For Rotation Angle to start the process.

2. The car starts, and proceeds up the ramp onto the wheel.

• Rotation Sensor 7 is attached to wheels that spin as the car moves, the car goes forward 100 rotations and stops

3. Light Sensor 6 is attached to a toothed gear and crank system allowing you to move it in front of each of the headlights.

• Turn on one of the headlights.
• Program the sensor so it Waits for Brighter and then turns off the headlight and turns on the other headlight/
• Program the sensor so it Waits for Brighter and turns off the headlight.

4. Turn everything off and signal that the check is complete.

· Repeat the process for all three packages.

5. The Program Page should include:

• Text boxes for the heading and explanatory information.

This addresses the main design criteria to receive a B for your robotic arm project.

1. Rotation Sensor 5 is the On / Off switch; use the Wait For Rotation Angle to start the process.

2. The car starts, and proceeds up the ramp onto the wheel.

3. Rotation Sensor 7 is attached to wheels that spin as the car moves, you must find out:

• Does the car go forward? Have the whistle tweet if it does. Then stop the car.

4. Light Sensor 6 is attached to a toothed gear and crank system allowing you to move it in front of each of the headlights.

• Turn on one of the headlights.
• Program the sensor so it Waits for Brighter and signals that the headlight is on.
• Turn the headlight off.

5. Turn everything off and signal that the check is complete.

6. The Program Page should include text boxes for the heading and explanatory information.

This addresses the main design criteria to receive an A for your car project.

1. Rotation Sensor 5 is the On / Off switch; use the Wait For Rotation Angle to start the process.

2. The car starts, and proceeds up the ramp onto the wheel.

3. Rotation Sensor 7 is attached to wheels that spin as the car moves, you must find out:

• Does the car go forward? Have the whistle tweet once if it does. Then stop the car, reset the rotation sensor to zero and have the car go in reverse, make the whistle tweet twice when it does.

4. Light Sensor 6 is attached to a toothed gear and crank system allowing you to move it in front of each of the headlights.

• Turn on one of the headlights.
• Program the sensor so it Waits for Brighter and signals that the headlight is on.
• Turn the headlight off and turn on the other headlight.
• Program the sensor so it Waits for Brighter and signals that the other headlight is on.

7. Turn everything off and signal that the check is complete.

8. The Program Page should include text boxes for the heading and explanatory information.
