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
User this flywheels construction for experiments in physics. Start rotating the wheel and they would accumulate energy. You can try to calculate this energy and to measure how fast it would be consumed.
The construction is built with LEGO Mindstorms EV3
Building instructions for the One Attachment. Built from LEGO Mindstorms EV3 parts and with an Ultrasonic sensor we've used this attachment to accomplish most of the missions at FIRST LEGO League 2013.
SIngle robot attachment, many points.
If you take a look at the videos for this attachment you will see a nice idea on taking the track and the ambulance. These two vehicles from the FIRST LEGO League 2013 competition had to be collected and returned back to base.

Building instructions for the LEGO Mindstorms robot attachment used at the FIRST LEGO League Natures Fury Competition. This robot attachment takes two of the building and moves them without demolishing them. It is a good example of the use of gear wheels and worm gear. The gear wheels move levers in opposite directions.
Building instructions for the EasyBot LEGO Mindstorms robot using in many of our courses and tutorials. This EasyBot has two motors and two front wheels. The third wheel is...well, check it out, see how the third wheel is built.
Attachment part of a series of robot attachments for accomplishing the FIRST LEGO League 2013 competition. This specific construction lifts the two vehicles. It uses rubber bands for locking the levers. Take a look at the video tutorials for details explanation on how it works.

Kiril Mitov's most favourite attachment. To quote him "I had a really great fun building this attachment and recording the videos for it".
It's an attachment with a Rubber band and a Flywheel and a Gear Wheel and a Worm Gear. So much knowledge in just one small attachment. The goal of the attachment is to be able to have an active attachment without actually having a motor. So you can place that attachment and it will do the work for you instead of using a motor to power it.
Build with LEGO Mindstorms EV3 set.
