Maze Basics
What type of sensor does the VR Robot use to detect that it has made physical contact with a wall?
The Bumper Sensor
What sensor detects physical contact with walls
BUMPER SENSOR
What sensor measures how far the robot is from an object without touching it?
D.S
What is the sign for less than equal to.
<-
What value does the bumper sensor report when pressed?
True.
Which unit does the distance sensor usually measure in?
mm or in
Which heading is used to move the robot forward in a maze?
0
How can you use a bumper sensor to make the robot stop?
Use a “wait until bumper pressed” or conditional block to stop movement.
How can the distance sensor prevent collisions?
By programming the robot to stop or turn when the sensor detects a close object.
How can the robot know when it has reached the end of a maze?
Using a stop driving block
What is one way to make the robot avoid crashing walls in a maze using the bumper sensor?
Program it to turn when the bumper is pressed
What block compares distance sensor readings to make decisions?
Logic Operators
Why is it important to plan a sequence of moves before programming the robot through a maze?
Planning prevents errors, reduces collisions, and ensures efficiency.
How many values does the bumper sensor report?
2
How can combining distance and bumper sensors improve maze navigation?
Distance sensor avoids collisions ahead; bumper sensor ensures backup safety if a collision occurs.
