In the EV3-G software, you could use negative numbers for power and rotations. In this episode, we would look at what is the meaning of this numbers and make a few notes of where the teacher must be more careful.

Once you start turning how to do you a whole 180 degrees turn. The robot almost does it, but not completely

We will share the idea behind that challenge and how to conduct the challenge in a classroom.

Let's make a competition - there is a pole that the robot must turn around and return home.

How to align the wheels and how much should you push for this solution?

There were a few problems with the 40 teeth gears that we were using. Let's list some of them

Build a similar mechanism to this one. Similar, but for your robot. This is the task for you. Try, give yourself half and hour or even an hour.

Time to lift the robot. The first approach is by using the 40 teeth gear wheels that come with the LEGO Mindstorms EV3 and NXT robotics sets. 

Remember the passive/active attachment separation that we are making at FLLCasts.com. This applies for all the attachments and in this Episode, we are looking at how to use a passive attachment.  

What is the end result? - have the attached on the mission model. What is the mechanism the would make the robot hang on the mission model.

Note for the teacher on how to organize the class to use different robot base constructions to accomplish the mission for lifting.

Build a robot base to use in the course. You can use the robot base provided by us or you can build one yourself. 

Don't limit yourself to the box and think of different ways to lift the robot. 

How to organize the different robots and group of students when working on lifting the robot.

Where should you lift the robot? Especially if you don`t have the mission model that we are using

How should an instructor use this course when working with students and a group of students in school

We've already build a number of resources for lifting at FLLCasts.com. But at the end of this course we would have a robot that lifts itself and hangs on the mission model.

The FIRST LEGO League competition is similar each year. With a little experience you could accomplish most of mission. The goal of this episode is to introduce you to the course, its purpose and approach.  

In this episode we combine in a single program the previous two programs for moving forward and backward. 

Now that we know how to make the robot move forward let's see we can make it move backward. 

In the RobotC software we could make the robot wait for a couple of seconds by using the wait function. This will give the motors a chance to work and this will actually move the robot. 

We are ready to build the first program for moving the robot forward and backward. We learn how to build simple programs for moving the program. But it is not that easy...downloading to the robot does not always result in the robot moving. 

The comunication between the motors and the controller should be configured in the RobotC software. Each motor could be connected on a different port and the goal of the video is to show you how.
