PPT-Basic Line Follower (NXT)

Beginner Programming Lesson LESSON OBJECTIVES Learn how humans and robots follow lines Learn how to get a robot to follow a line using the NXT Color Sensor Learn how to get a robot to follow a line using the NXT Light Sensor. The threshold in this case is 25cm We can create behaviors that tell the robot to go forward until Ultrasonic sensor detects something closer than 25cm The threshold is just used to determine at which point the robot should be peforming a different NXT-Step Programming Workshop.

Beginner Programming Lesson. LESSON OBJECTIVES. Learn how humans and robots follow lines. Learn how to get a robot to follow a line using Color Mode on the EV3 Color Sensor. Learn how to follow a line until a sensor is activated. Dr. Mohammad Kilani. Class 5. CAMS. Introduction to Cams. Cam-follower systems are frequently used in many kinds of machines. Common examples of cam follower systems are the automobile engine valves, which are opened by cams. . Oscillation is back and forth motion about a pivot point. It is measured in terms of both the angle of throw (amplitude) and the period of time for one complete cycle (periodic time) or the number of cycles in a given time (frequency).. What are Cams?. Cams are mechanical devices that convert . rotary oscillating. or . linear. motion into a . linear. or . reciprocating. motion to carry out useful work.. There are two links namely the . Engineering System : Mechanisms . Content. Cams. Eccentrics. Ratchets. Inclined plane. Crank/Slider. Screw. (Bearings). Specially shaped piece of metal or plastics. Edge/profile of the cam guides the motions of a follower. Line Followers: Basic to Proportional. ADVANCED EV3 PROGRAMMING LESSON. © 2015 EV3Lessons.com, Last edit 4/5/2015. 1. Lesson Objectives. Evaluate and compare different line followers. Learn to use the concept of “proportional” to create a proportional line follower. How do humans sense light? . Provide an example “stimulus-sensor-coordinator-effector-response” framework using the human light sensor.. Give some examples of light sensors in engineering systems.. Can you think of a method to have the robot follow the line using turns? Describe how it would work.. 2. Pre-Activity Quiz. How does a light sensor work? Does the light sensor detect white or black as a higher amount of light reflectivity? Absorbance?. Developed by Tony Ayad. Updated by LeRoy Nelson. California - Los Angeles Region FLL.
