1 Provide a ldquostimulus-sensor-coordinator-effector-responserdquo framework using human eyes as the light sensor
Humans have two eyes that collect light that falls on objects in front of them and helps them ldquoseerdquo the objects
Stimulus-to-response framework sight of a scary object such as a wasp gt two eyes gt human brain gt signal to leg muscles gt run to safety
2 Provide the logic for a program for a LEGO robot that enables it to follow a flashlight
Use two light sensors attached to the front of the taskbot
Turn the taskbot towards the sensor (of the two) that reads the higher intensity of light
Follow the Light Pre-Quiz Answers
Your brain commands your hand to perform a task depending on what it has seen
4
Human-Robot Similarities
Similarly the NXT brick can command its motor to move the taskbot as we will now do in an activity
5
Objective ndash Your Engineering Challenge
Build a LEGO taskbot with a light sensor and program it to make the robot follow a flashlight as the light beam is moved around by a person
Follow the Torch Light Activity
6
What is the engineering design process
A series of steps used by engineering teams to guide them as they develop new solutions products or systems
Steps1 Define the problem
2 Identify criteria and constraints
3 Brainstorm possible solutions
4 Generate ideas

7 Build a prototype to test
8 Refine the design
Engineering Design Process
The process is cyclical mdash it is usually necessary to test and modify many times to improve your design and get it right
7
Letrsquos get started Divide the class into groups
of three students each
Distribute the LEGO taskbots and the parts necessary to attach the light sensors to them
Have each group attach a light sensor to its taskbot following the instructions in the LEGO base set
Follow the Torch Light Activity
Discuss as a group the logic of the program Write down your programming design Create test and debug your program

Letrsquos get started Divide the class into groups
of three students each
Distribute the LEGO taskbots and the parts necessary to attach the light sensors to them
Have each group attach a light sensor to its taskbot following the instructions in the LEGO base set
Follow the Torch Light Activity
Discuss as a group the logic of the program Write down your programming design Create test and debug your program

For the LEGO light sensor light gt NXT light sensor gt (transmission to coordinator) value sent to NXT brick via wire gt brick sends a signal to the NXT motors gt robot moves
2 Provide the logic for a program for a LEGO robot that enables it to follow a flashlight
Use two light sensors attached to the front of the taskbot
Turn the taskbot towards the sensor (of the two) that reads the higher intensity of light
