Tasks for STEM classroom and home exercise to get you used to using the LEGO Mindstorms Touch sensor. Solve them, build a program, record a video and upload your solutions below.
The way sensors and programs work in a robotics system is sometimes not-intuitive for a beginner, but nevertheless very logical. Building a program for a touch sensors for "Press->Go->Press->Stop" using the EV3-G software could be quite challenging at the beginning even for experienced teachers, students and robot builders.
We create a program for detecting when the Touch Sensor was Pressed/Released. Move until it is pressed, continue when it is released.
Complete introduction to the LEGO Mindstorms EV3 Touch sensors from the very first step. In this video tutorial we program the robot to stop on touch sensor pressed. Again, this is based on your feedback that much of our tutorials in previous years were a little more advanced and that we have never made a proper introduction. A few more videos on touch sensor will follow after this
Robot tasks to exercize how to position on the field using only motors. STEM classes could use it to demonstrate mechanical imperfections in constructions and how important using sensors in this LEGO Mindstorms Robotics sets is
The way you move the robot is always imprecise. Don't TRY to fight with this. Programming motors for competitions like the FIRST LEGO League (FLL) or World Robotics Olympiad (WRO) is not very different from programming the motors in the STEM classes. But there are a few things you should have in mind.
Experiment with moving the robot in different geometrical figures. The tasks could be used in STEM classes for introducing students to geometry and math.
Move the robot using the Move Steering block. We explore what the different values for Steering mean and how to use them. We also explore how the motor is configured to run for a number of rotations or seconds and what is the difference.
First time programming the motors of the robot using the EV3-G software installed on a computer. We would explore how to move forward/backward and turn with the robot.
The LEGO EV3 Mindstorms brick can be programmed from the brick itself. The motors can be moved forward/backward and even simple programs could be implemented without even touching the EV3-G software at the computer
Tasks for introduction on building robots.
Based on your feedback we've build a course for introducing new students to the LEGO Mindstorms EV3 programming and construction. It is designed for school groups, competition teams and students alone in home that can get our feedback on their progress
