In this lesson, students will learn how to program his/her wheeled Lego EV3 Robot to perform a three point turn and use the Ultrasonic Sensor as a “parking sensor," so that his/her wheeled robot stops a given distance from an obstacle when it is reversing. Lesson 3 of 4.
This is lesson three of four lessons of the project Robot EV3: Build It!, Program It!, Sense It! Operate It!, in which students will design, build and create a program for a Lego EV3 robot that can sense its environment and act by making a sound when it is finished.
For this lesson students may use a robot design with a driving base OR students may use a previous robot (refer to previous lesson, "Robot EV3: Build It!").
In this lesson, students will learn how to program his/her wheeled robot to perform a three point turn and use the Ultrasonic Sensor as a “parking sensor," so that his/her wheeled robot stops a given distance from an obstacle when it is reversing.
Students may continue working from the Programming Palettes (refer to lesson 2 of 4, "Robot EV3: Program It!) at the bottom of their computer screen onto the Programming Canvas by selecting the plus (+) tab OR student may begin with a new Programming Palettes by left clicking on file, and selecting new program. Students will work in groups of 2 or 3 to break down the problem and build towards a solution to successfully complete their program.
As a Teacher, I highly suggest that you take pictures and or video clips of your students throughout all of the lessons. It can serve as an awesome demonstration/model for the final project to share with your students toward the end of lesson 4 (Robot EV3: Operate It!).
