Join Olivia Chiu Stone for an in-depth discussion in this video Motors and sensors, part of Learning Lego Mindstorms.
- [Voiceover] The motors and sensors in the EV3 kit…help your robot interact with the world around it.…To help your robot move around,…the Mindstorm's EV3 kit…comes with two types of motors,…a large motor and a medium motor.…Both motors have a built in rotation sensor…that can tell me to the degree, its position…which helps with precise control.…The large motor is a stronger but slower motor…that can run at 160 to 170 RPM.…
This is designed to be used to drive a robot around.…The medium motor is a less powerful…but faster motor…that can run at 240 to 250 RPM.…It can respond more quickly than the large motor…and usually used to move a part of a robot…such as an arm.…Moving your robot around…without any sensor feedback…is like driving with your eyes closed.…My robot needs sensors to get feedback…about its environment…so it can move around more intelligently…and avoid running into things.…
The Mindstorm's EV3 kit…comes with three sensors…that provide different ways to get information…about my robot's surroundings.…The color sensor is used to detect colors…

Learn how to unpack the hardware, connect to the programming interface, run prebuilt programs, and control the motors and sensors. Chapter 6, "Adding Flow to a Program," covers advanced programming topics such as transferring data between blocks, using variables to store temporary data, programming conditional logic, and looping actions to run again and again. By the end of the course, you'll have the skills to bring your own robotic creations to life.
