• Moves the VR Robot forward or backward.

• Turns the VR Robot left or right a specific.

When pressed, the Bumper Sensor returns a value of 1.

• True

• False

What will happen when the Bumper Sensor is pressed in this project?

• The VR Robot will drive in reverse.

• The VR Robot will reach maximum velocity.

• The VR Robot will drive forward.

• The VR Robot will stop driving.

Which kind of block is the <Pressing bumper> block?

• "C" block.

• Stack block.

• Boolean reporter block.

• Hat block.

Which of the following is the best reason to use the Bumper Sensor?

• To instruct the VR Robot to report the distance of the nearest object.

• To help VR Robots using information from the environment, and then make decisions (e.g. Stop when it collides with a wall).

• To report the velocity of the VR Robot in order to complete the task faster

• To set the Pen position down in order to track the path of the VR Robot.

What will happen when the (Distance from) block reports that it is less than 50 millimeters (mm) from an object?

• The VR Robot will turn right for 90 degrees.

• The VR Robot will stop.

• The VR Robot will drive forward.

• The project will restart.

What will the <Pressing bumper> block inside the [Wait until] block report in this example?

• Yes (bumper released) or No (bumper pressed).

• Drive forward (bumper pressed) or Drive in Reverse (bumper released).

• Turn right (bumper pressed) or Turn Left (bumper released).

• TRUE (bumper pressed) or FALSE (bumper released).
