Improved Grab & Lift EV3 Grabber by RobotECK
This "Improved" EV3 Grab & Lift Grabber by RobotECK ( https://www.youtube.com/watch?v=jlShBefAST4 ) refines the "Basic" one done a year before ( https://rebrickable.com/mocs/MOC-9360/DLuders/ev3-grab-and-lift-grabber-by-roboteck/#comments ). A slick EV3 Program for it is shown on https://www.youtube.com/watch?v=eCBkrc33HeE , but you can use a much simpler program.
