Introduction

This lesson was designed to introduce the ultrasonic sensor and apply proportional control to assist a LEGO car in completing a task.  We will design a robot that can maintain a constant distance between it and the car in front of it using a proportional controller.  

Materials

LabVIEW for LEGO MINDSTORMS
LEGO MINDSTORMS NXT kit

Teaching Standards

In this lab students have the opportunity to understand the following:

1. How to create a system that controls movement to accomplish a goal
2. Ultrasonic Sensors
3. Filtering noise
4. Proportional Control
5. Computer programming
6. Electronics and motors
7. Dynamics
8. Team work and collaboration

We recommend linking your project's content to the nationally recognized Common Core Standards for literacy in science and math.

This lesson is part of the ROBOT CONTROL ACTIVITY SEQUENCE.  See recommended lessons below for the other activities in the sequence, or visit the Activity Sequences page on the Tufts CEEO project site.
