LEGO MINDSTORMS

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

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

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. 

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.

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.  

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

Calculate the number of rotations you have to do with the motor to rotate the final small 8 teeth driving gear wheel to 1.25 rotations?

What should you do as a teacher when the students are calculating the gear ratios and number of needed rotations?

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.
