This block works for EV3!
The EV3 robot has a cool arm, which can be used for flipping switches or for pushing or dragging objects.
The arm can be set to one of its two positions: Up or Down:
Note: When the arm is in its lowered position, is blocks the Ultrasonic sensor, meaning the robot will think there is an obstacle in front it, while it’s just its arm. If you plan on using the Ultrasonic, make sure to move the robot's arm to the 'up' position so that the sensor's beam is not blocked.
