Overview of what is going to happen in module 3

Sometimes the answer that you get by calculating seems not to be right. Is it the calculation that is wrong. Probably it is not the calculation, but something is happening with the robot. 

Tasks for introduction on building robots.

This robot could quite possibly be build from a single EV3 core and EV3 resource sets. It uses fewer parts and only three motors. There are additional parts that could be skipped when building the robot and we have added these parts only as to make the construction more complete. 

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

In this Episode, we create the next attachment for the box robot two. It is again a pinless attachment, attached to the frame that transfers the motion to a vertical axle. 

In this video we look at the way this robot uses the LEGO Mindstorms EV3 motors. How are they attached and the what the rotation of the motor is transferred to the attachments.

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.

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

It this episode we would present you with our attachment for lifting the robot. 

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.

Connect the attachment to the box robot and find the correct number of rotations of the middle motor that would bring the robot up and forward and would attach it to the mission model.

How great is the great attachment for lifting that we built in this course? How many times can it lift the robot without making an error? How great are your attachments and how could you test them? - the answer is simple. Just try 10 times and they should work at least 9 of them as our attachment is.

Think of an attachment that leaves the Gecko on the mission model. Don't use the robot attachment that we already have. Just the box robot and the gecko. Nothing should support the Gecko when it is hanged on the mission model. 

Try to build the attachment following the instructions. Use it to actually solve a mission from any competition (like taking loops)
