The EV3 Ultrasonic sensor is used to measure distance. We can use the sensor to detect whether there is a wall or some other solid object ahead and how far it is. But to master it usage, first we should know how does it work
In part 1 of How to on Gears tutorial I introduced you to the basics of the gear systems. Now we are going to examinate gear systems with more than two gears and take a look at cascade gear systems.
This is a teacher's note about the math behind calculating gear ratios with for our lifting attachment. It math model we build in previous tutorials is not exactly correct and here is the explanation why.
We show the principle of solving the next FIRST LEGO League (FLL) Nature's Fury 2013 competition missions. Again, without any programs, but just the principles of using one attachment for most of the missions.
In Robopartans classes we needed a few parts the the robot could lift in a competition. These is a box that is suitable for this
We already know how to use the rotation sensor. Now it’s time to explore more of its functions.
Before we get started, we would need to connect the robot to the computer so we can test our programs.
We want to make sure you remember last time’s lesson before we move on.
