Building Instructions

Classical third wheel for LEGO Mindstorms robots. This construction comes from the NXT world and the wheel is available in the NXT set. 

A very simple base of the robot that could be used for adding attachments.

The CubeHunter uses the ultrasonic sensor to detect a ball or cube. Next, the robot catches it and reads the colour of the object using the EV3 colour sensor. The building instructions are suitable for classes with students and if you are working alone at home.

It's the third version of the VEX IQ Easy Bot with rotated Robot Brain and castor wheel.

It's the second version of VEX IQ Easy Bot. It's simple as the first one, but the motors are rotated.

VEX IQ version of an Easy Bot. It's simple and appropriate for classes of students. 

Drawing on how to cut a pipe to be able to collect and store balls in this pipe. The sheet format is ISO A4 and the drawing size is real (100% scale)

Instructions for building a steering chassis from LEGO EV3 Mindstorms. It uses EV3 Large motor to power the rear wheels and EV3 Medium motor for the steering mechanism. Find building instructions for the remote control here.

Instructions for building remote control. It uses the rotation sensor to determine the steering and touch sensor for handling the movement. Find building instructions for a suitable chassis here. 

Together the controller and the car look like this:

This here is a base for a robot that has the brick Upside Down. Have you seen Stranger Things? We would admit that this robot does not look exactly like a 'Demogorgon', but this here is the challenge. Can you use this base and make the robot look like a Demogorgon. Add a picture to the comments section below the material.

Do you have other ideas for Demogorgon? Build them with LEGO and add a picture below this material or send it to [email protected]. We would feature it at FLLCasts.com.

Building instructions for a LEGO Mindstorms EV3 Robot that we call CastorBot, because it uses the castor ball. 

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

Building instructions for a VEX IQ attachment for throwing balls with rubber bands.

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

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.

Frame for adding attachments on the robot. When using a frame it is very easy to quickly add and remove pinless attachments from the robot. The whole frame could be removed.

The frame contains parts from LEGO Mindstorms EV3.

For the FIRST LEGO League 2016-2017 Animal Allies we prepared an attachment for lifting the robot. The idea of the attachment is to show how you could lift the whole robot with a system of gear wheels, levers, and scissors constructions.

Built mainly from LEGO Mindstorms EV3 parts but could probably be constructed from NXT sets.

Building instructions for a LEGO Mindstorms EV3 Robot that we call the Five Minute Bot because it could be built in Five Minutes.

Note: If the robot is making inconsistent turns due to the floor, modify the castor wheel so it is placed further back in the construction. Thus the center of mass falls more over the tires and the turns are more consistent.

Building instructions for Module 1 of the Modular EV3 LEGO Mindstorms vehicle - the Trunk.

The goal of this robot is to teach students how to build modular robots. This first part is just one of the modules.
