LEGO MINDSTORMS

We calculate the number of rotatios when a gear system is involved. The driving wheel will have to do a number of rotations for the driven wheel to rotate to a desired number of degrees. In our specific case when the driven gear wheel is rotate to about 90 degrees the legs will lift the robot.

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. 

The mindstorm motors have an intersting "bug". This bug is that the motors turn absolute to the starting position of the motor.

This video tutorial shows how the LEGO Mindstorms EV3 Ninja Motorcycle robot works. It's a nice demonstration with the robot moving forward, backward, and slightly to the left and right. 

The goal of this lesson is for students to exercise with the ultrasonic sensor along with controlling the middle motor. It is important to not the many ways in which gear wheels are used in the robot. 

This video tutorial contains a detailed explanation on how we accomplish the FIRST LEGO League 2018-2019 Into Orbit mission called M09. STRENGTH EXERCISE. I could think for a couple of missions in previous years that require lifting a heavy object. Let's see how this mission could be accomplished.
