• Grab

Oh no, the delivery is running late! Fortunately, this warehouse robot is designed to grab and transport objects, making it the perfect helper.

The robot uses two medium motors for movement and a third medium motor to operate its grabber. Located at the front of the robot, the grabber is made from two double angular liftarms, each connected to a gear. This mechanism allows the robot to open and close its pincer to securely pick up and move boxes around the warehouse.

Antares is the brightest star in the Scorpius constellation.

The robot's main purpose is to show two different grabbing mechanisms - one vertical and one horizontal. The vertical pincers use a medium motor and the horizontal pincers use a large motor. Additionally the robot has a sting mechanism which uses another large motor. For a head it uses an EV3 ultrasonic sensor. With the sensor, the robot can sense when the prey is close enough for a suprise attack.

Building instructions for the most simple grabber using just one Large EV3 LEGO motor. It has one static lever and one active lever.

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.

This is version 2 of the LEGO Mindstorms Grabber. It makes use of 4 gears to make both levers active.
