Building instructions for a LEGO Mindstorms EV3 Ambulance Robot Attachment for the FIRST LEGO League 2013 Nature's Fury robotics competition. The attachment grabs the ambulance car and slightly lifts it. The rubber bands help with triggering the attachment at the right time
These are building instructions for one of the greatest LEGO Mindstorms attachments that we've built. Super simple and easy to follow and at the end, you have an attachment with a rubber band that controls a lever and that could lift objects from the field. It could lift them up. Also because it is with a rubber band you don't need a motor and you could use the motor for other attachments.
