Active attachment for changing gears direction - part 3: moving up&down

In this video lesson I am building a LEGO Mindstorms EV3 active attachment powered by a small gear wheel. The attachment could move up and down, it is very useful for collecting objects. It could easily be adapted and used on other robots.

We are making a parallel with Video Lesson 56 from the series and we are also showing ways to improve the stability of an axle which is most of the time neglected, but could lead to great problems.

EV3 basics course. Motors control and program from the brick (part3)

The LEGO EV3 Mindstorms brick can be programmed from the brick itself. The motors can be moved forward/backward and even simple programs could be implemented without even touching the EV3-G software at the computer

This is the third version of the LEGO Mindstorms Grabber. This time we use a LEGO EV3 Medium motor and worm gear to make the two levers move smoothly and symmetrically.
