Summary

In this chapter, you built an R2-D2 robot using the application of gears as well as a simple machine pulley. You solved two tasks: one to rescue Padme and another to pick up the Jedi Master and go to the planet Dagobah. The purpose of this chapter was to strengthen your construction skills using the pieces given in your LEGO BOOST kit. By now, you should be able to build robots that have human-like movements, such as the neck movement of R2-D2. You should also be able to design robots that are like real-life/sci-fi character robots that you have seen either onscreen or in real life. In the next chapter, you will be building an automated entrance door with the help of a color sensor. The door construction will resemble the entrance that you see at malls/offices where the door will open only for specific people and not for others. It will be a fun task for you.
