Exploring LEGO SPIKE Prime Components

What does the "S" in LEGO SPIKE Prime stand for?

• Science

• Speed

• SPIKE (it is the product name, not an acronym)

• System

Which component in the LEGO SPIKE Prime kit serves as the main "brain" or controller of the robot?

• The motor

• The Hub

• The color sensor

• The force sensor

How many ports does the LEGO SPIKE Prime Hub have for connecting motors and sensors?

• 4

• 8

• 6

• 10

Which sensor in the LEGO SPIKE Prime kit would you use to detect how far away an object is from the robot?

• Color Sensor

• Force Sensor

• Distance Sensor

• Gyro Sensor

A student wants to program their LEGO SPIKE Prime robot to stop moving when it detects a red-colored surface on the ground. Which two components would work together to accomplish this task?

• Distance Sensor and Large Motor

• Color Sensor and Large Motor

• Force Sensor and Medium Motor

• Distance Sensor and Force Sensor

A student connects a Medium Angular Motor to Port A and a Large Angular Motor to Port B on the SPIKE Prime Hub. How would the use of these two different motors affect the robot's movement, given that the medium motor produces less torque but higher speed compared to the large motor?

• Both motors would move the robot at the same speed and force

• The medium motor side would move faster but with less pushing force, while the large motor side would move slower but with more pushing force

• The large motor would make the robot move faster than the medium motor

• The medium motor would provide more torque than the large motor

When building a LEGO SPIKE Prime robot, a student uses the built-in gyro sensor inside the Hub. Which of the following tasks can the gyro sensor help the robot perform more accurately?

• Detecting the color of objects on the floor

• Measuring the distance to a wall

• Turning at a precise angle, such as exactly 90 degrees

• Measuring how hard an object is being pushed

A student is designing a robot that must pick up an object and place it in a specific location. The robot needs to know when it has successfully grabbed the object. Which sensor would be most appropriate to detect the moment the robot's gripper has made contact with the object, and why?

• Color Sensor, because it can detect the color of the object being grabbed

• Distance Sensor, because it can measure how close the gripper is to the object

• Force Sensor, because it can detect when physical contact or pressure is applied

• Gyro Sensor, because it can detect the change in angle when the gripper closes

A student is building a robot that must navigate a maze autonomously. The robot needs to detect walls, avoid obstacles, and follow a colored path on the floor. Using only the LEGO SPIKE Prime components, which combination of sensors would best allow the robot to complete all three tasks, and how would each sensor contribute?

• Two Distance Sensors for walls and obstacles, and one Color Sensor for the path — the distance sensors detect nearby walls and obstacles while the color sensor follows the colored path

• One Force Sensor for walls, one Gyro Sensor for obstacles, and one Color Sensor for the path — the force sensor detects wall collisions, the gyro tracks direction, and the color sensor follows the path

• One Color Sensor for all tasks — it can detect walls, obstacles, and the colored path at the same time

• One Distance Sensor for walls and one Force Sensor for the path — the distance sensor detects walls and the force sensor follows the colored path

A student's SPIKE Prime robot is programmed to move forward until the distance sensor reads less than 10 cm, then turn 90 degrees using the gyro sensor, and repeat. However, during testing, the robot consistently overshoots its 90-degree turns. Using your knowledge of SPIKE Prime components and programming logic, what is the most likely cause of this problem and what adjustment should the student make?

• The color sensor is interfering with the gyro sensor; the student should disconnect the color sensor

• The robot is moving too slowly; the student should increase the motor speed to fix the turning

• The gyro sensor may be accumulating drift error over multiple turns, or the motor speed during turning is too high causing the robot to overshoot; the student should reduce the turning speed or recalibrate the gyro sensor between turns

• The distance sensor is giving incorrect readings; the student should replace it with a force sensor
