Lego Technics RC bottle grabber v2

This is an enhanced version of the previous one. Lever/gear mechanism is moved as close to the motor as possible. Thus transfering much less torque - works fine even on higher RPMs. But even remaining torque on backward direction was sufficient to move both tracks - an additional specific blocker on a right track gear had to be added. Now when motor is rotating backward, grabber turns left (because the right track is blocked). Jaws are using one motor to grab and then to lift - the functionality should be clear from jaws detail video near the end of clip.
