This robot extends the Tetrix Box Robot chassis for FTC competitions with an additional arm. The arm could be used for lifting and placing objects and could be quite useful.
There is a special rubber band at the end of the arm, because there are not enough parts in the Tetrix set and we had to use a rubber band. But the principle of the arm is interesting, useful and you should be familiar with it - the arm keeps the motors always in the right orientation.
