Building Instructions -

• LEGO MINDSTORMS EV3

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

This module is meant to be used in EV3 Kinesthetic and Memory Game and is attached to the base of the robot. This module uses the rotation sensor in the medium motor to detect how much the players had turned its wheel.

Winter might be far away or it might just be coming - depending of course on where you are in the world. But you can always spend a few hours having fun with a LEGO Mindstorms Snowmobile. A really challenging construction that requires good preparation, concentration and a lot of efforts to complete. Same is going to the mountain in the winter. But the reward at the end is worth it. 

Building instructions for a LEGO Mindstorms EV3 robot base. The attachment of the motors is quite interesting. We follow the angles of LEGO technic to attach them. This construction has some difficulties turning to the left and to the right. But if you have to take on an obstacle that high this is one of the options. 

You can use all kinds of wheels on this robot - EV3, NXT or others. It doesn't actually matter.

Building instructions for the Pinless Rubber Band Attachment:

Chronos means time in Greek.

What's the time? Time to build a cool robot! This robot is made to look like a clock. The two hands are each connected to a motor and are positioned between the two motors. This makes it simple to build, while also being effective in showing how a clock works.

An example program moving the seconds and minutes hands of the clock can be found here.

An example program designed to teach children to read the clock can be found here.

Not all LEGO Mindstorms EV3 Robot should be aligned horizontally or vertically. It is quite possible to have the brick and the motors attached in such a way that the robot is at a certain angle. 

This is a very useful small construction that could be used as a base and extended with hands and heads or other interesting ....robot body parts.

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.

Build from LEGO Mindstorms EV3 parts.

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

Building instructions for a LEGO Mindstorms EV3 Multi-axles mechanism

Building instruction for both EV3 and NXT. The whole catapult is build in exactly 78 steps.

One LEGO gear is powering two LEGO Gears and at the end, from one motor we rotate two axles in opposite directions. Follow the building instructions.

This LEGO Mindstorms Attachment has three gears, one frame and two axles. The goal of the attachment is to use the gears to change the direction in which the motion is transferred.  

Interesting and useful attachment for dropping a LEGO human at a specific location. It uses a lever and a gear wheel. When the lever is pressed the wheel rotates.

The attachment is constructed from LEGO Mindstorms EV3 sets.

In all building instructions for LEGO robots it is important to have the motors attached to the brick in more than one place. In the following construction, there is a beam connecting the two motors which has exactly this purpose. It makes the construction much more stable. Try removing this beam for example and see what will happen. Would the robot be able to move?

Many different types of wheels could be used. Both NXT and EV3 or from other LEGO technic series.

This LEGO attachment connects a LEGO Mindstorms EV3 Motor with a LEGO Technic Linear Actuator. The connection is through a couple of gears which makes the whole instructions quite interesting and useful as an example. 

The attachment was used during FIRST LEGO League 2014 Robotics competition.

This robot is made to serve the best tea in the whole continent! It is based on the Easy Bot from EV3. As its predecessor it is based on LEGO Mindstorms EV3. It uses two large motors to move around. The best part of the robot is the cup holder, that has a cool cup that shows the KISS principle.

This WRO robot is designed to collect a lot of ping pong balls in its container. It's built with LEGO Mindstorms EV3 45544 and 45560 sets. These are the LEGO Educational sets. The robot has two chains that collect the balls and push them into the container attachment. This is one of the larges robots we've uploaded at FLLCasts yet. You could learn a lot by following the building instructions and paying attention to the details of how this robot is built. All the alignment, all the connections. Really beautiful.
