• A modular robotic platform

• A manual vehicle

• A stationary machine

What can be added to the driving base to help it react to its environment?

• Wheels

• Lights

• Sensors

• Antennas

What are some functions of the sensors added to the driving base?

• Painting and drawing

• Detecting objects and avoiding collisions

• Playing music

• Sending emails

What does an ultrasonic sensor use to detect objects?

• Light waves

• Sound waves

• Radio waves

• Infrared waves

What happens to the sound waves sent by an ultrasonic sensor?

• They are absorbed by the object

• They pass through the object

• They bounce back to the sensor

• They change color

What do the reflected sound waves from an ultrasonic sensor measure?

• The color of the object

• The distance between the sensor and the object

• The speed of the object
